Description:
Drag the files you want to optimize to the files grid in FileOptimizer, right click with the mouse to open the contextual menu, and then click on Optimize. This will process all supported files added, and overwrite them with the optimized version.

Alternatively you can add the files and directories to process on the program’s command-line, or dragging them to the executable file. A context menu for Add files, also does it.

By default, FileOptimizer will remove additional metadata, and other unneeded information, but will keep original files in your recycle bin just in case you want to further modify the originals.

Frequently Asked Questions (FAQ)
Why are several downloads available?
Available downloads come separated in a binaries (executables) form, suitable for x86 and x64 architectures, and in a source code archive. Both are usually available in several package formats.

What is the sense of FileOptimizer, if standalone tools are already available?
Indeed you can manually execute the commandline tools that FileOptimizer uses as plugins, but this will be probably less comfortable. Specially if you consider you will need to execute one or another depending on the file format, and to chain some of them to obtain best results.

What is different in FileOptimizer compared to similar tools?
General idea on tools like PNGGauntlet, ImageOptim, RIOT, etc is essentially the same.
FileOptimizer is built-in with lots of plugins that allow it to handle a big variety of file formats. Optimized files are usually smaller than in competing products, or comparable at worst. It is easy to use, and at the same time easy to automate. Is a native Win32 application, being compact and fast, and works portable with no external dependencies nor access to the system registry. Finally it is free and open source.
At the moment, it is not much mature, lacks some features, and is not configurable at all.

Are optimized files identical to the original ones?
Optimized files, will look identical to the original ones, but internally they will be different in order to achieve the size reduction.
For images, bit depth reduction is used when possible. For instance an image encoded with 24 bit color depth could be resampled to 8 bit color depth if 256 colors of less are used. Quality should not be affected after the transformation.

Why are original file stamps not preserved after optimization?
FileOptimizer supports restoring original file attributes once it has been recompressed. This includes creation, and modification timestamps, but also read-only, system, archive and hidden attributes. To enable it, mark the checkbox “Keep file attributes” under “Options -> General”.

Have the optimized files same degree of compatibility as the original ones?
Generally yes, they have the same degree of compatibility. The exception is JPEG images, when you have enabled the User arithmetic encoding option. It generates smallest files with the same quality, but require recent software to render them.

Will optimized files load faster?
Definitively yes, optimized files are smaller, less information needs to be transferred from the internet, of from the local disk, and will load faster in a direct proportion with the size reduction.
Decompression speed of the optimized files is also proportional to the size reduction, because used compression algorithms are asymmetric (slow compression and fast decompression).

Does optimized files work on other platforms than Windows?
Yes, since they are the same format as the original ones, they will continue to work, no matter if they are rendered in a web browser, an Android or iOS application, or any other desktop program.

Why is the recompression process so slow?
The speed of the recompression depends on the particular format of the file.
Noticeably PNG processing is the slowest, because the brute-force recompression to squeeze them. As oposite, PDF and JPEG files should be encoded pretty fast.

Does it work on other platforms than Windows?
FileOptimizer is reported to work in some environments under UNIX based operating systems with Wine such a Linux and macOS.
For other platforms, you will need to install a virtual machine such as VirtualBox with Windows XP or later.

Why a particular format is not supported?
Even if I do my best to add new format support to FileOptimizer, I may have missed some.
If the format to add has available a Windows command-line tool to optimize it, it can be easily integrated on FileOptimizer, so please, let me know.

How can I disable a particular plugin?
You can use the INI setting DisablePluginMask= to allow excluding execution of certain plugins. For instance DisablePluginMask=leanify;advpng.exe will prevent executing any plugin containing in its name leanify or advpng.exe.
As you can see it is case insensitive, and allows more than one item to be specified by using semicolon (;) as separator.

Can I prevent certain file formats from being processed?
If they are supported by FileOptimizer, unless you could remove all the plugins used to treat this format, it will not be possible.
The workaround would be to not add those type of files.

I can appreciate some quality loss on PDF optimization. Why?
PDF are recompressed with no loss of quality, but images can be downsampled, and so on, allow certain lost of quality, specially at high zoom levels. You can control it under Options -> PDF -> Profile.

Why is Ghostcript always downsampling embedded images?
Ghostscript (more particularly the pdfwrite device) does NOT ‘optimise’ PDF files. Ghostscript interprets the input into a series of marking operations, which are then piped to a device. The pdfwrite device then produces a PDF file based on those marking operations. The output is unrelated to the input, except for the appearance. This is discussed in more detail in the Overview in VectorDevices.htm in the Ghostscript documentation. Because the input is fully interpreted JPEG images are decoded to a bitmap. If you then apply JPEG quantisation in the pdfwrite device the result will be a loss of quality (unsurprisingly, since JPEG Is a lossy compression scheme). At present, your only option is to not use JPEG to compress images in the pdfwrite output.

How is the command line syntax?
FileOptimizer command line arguments work like:
C:PROYECTOSFileOptimizerWin32ReleaseFileOptimizer64.exe "C:PROYECTOSFileOptimizer_Tests_ - copia"
Where:
- C:PROYECTOSFileOptimizerWin32ReleaseFileOptimizer64.exe: Is the full path where FileOptimizer executable is.
- "C:PROYECTOSFileOptimizer_Tests_ - copia": Is the full path of the folder to recursively process. Be aware enclosing it with double quotes as in the example, which is Windows mandatory if the folder contains spaces, or extended characters.
Alternatively you can specify only one single file instead of a folder:
C:PROYECTOSFileOptimizerWin32ReleaseFileOptimizer64.exe "C:PROYECTOSFileOptimizer_Tests_ - copiaav-214_.zip"
Where:
- C:PROYECTOSFileOptimizerWin32ReleaseFileOptimizer64.exe: Is the full path where FileOptimizer executable is.
- "C:PROYECTOSFileOptimizer_Tests_ - copiaav-214_.zip": Is the full path of the file to process.

Is there a way to silent install FileOptimizer?
You can specify the /S command-line swich to the installer, and it will install FO with no prompts:
FileOptimizerSetup.exe /S
Since it is implemented over NSIS, you can take a look at http://nsis.sourceforge.net/Docs/Chapter3.html#installerusageexamples for further reference.

Are there any other parameters available in the installer
Yes, you can use optionally:
- /AllUsers: Install for all users instead of current user.

How can I enable FileOptimizer log?
Simply check Optimize->Options->General->Log level, and set it higher to 0, depending on the information you want to log.

Where can I find FileOptimizer.ini or FileOptimizer.log
FileOptimizer.log and FileOptimizer.ini both sits were FileOptimizer executable is (FileOptimizer32.exe or FileOptimizer64.exe) when write permissions exist on that folder. If not, they will be stored under %USERPROFILE%, which usually resolves to something like “C:UsersJavier GutiérrezFileOptimizer.ini” or “C:UsersJavier GutiérrezFileOptimizer.ini”.
Remember you can use Windows search tool, to look for the file.

Why my HTML, CSS or JS files are not optimized being them supported?
As of version 6.50, optimization of CSS, HTML, Javascript and its derivatives is supported. They follow the same lossless concept as other formats, so once compressed they will render and look exactly the same as the original, but with a reduced file size.
Unfortunately those optimizations may cause your files to not be editable anymore by WYSIWYG tools such as Dreamweaver, and to avoid risks they are disabled by default.
To enable them, simply go to Options->CSS->Enable Tidy; Options->HTML->Enable Tidy and Options->JS->Enable JSMin.

How can I enable SVG optimizations?
SVG optimizations, are linked with HTML ones. You can enable them by checking “Options -> HTML -> Enable Tidy”. When enabled, results in smaller files, but can happen they are not editable anymore. Note that this applies to both SVG and HTML file types.

Are there any other files that are not editable after optimization?
Since focus of FileOptimizer is to be lossless in terms of appearance, other files could become not editable once optimized. For instance Photoshop’s PSD files, will have their text layers rasterized.

How can I enable lossy compression?
You can check “Options -> PNG -> Allow lossy optimizations” and ini settings JPEGAllowLossy=true, GIFAllowLossy=true.

How can I prevent users changing options?
FileOptimizer reads its options in the following order: HKEY_LOCAL_MACHINESoftwareFileOptimizer, HKEY_CURRENT_USERSoftwareFileOptimizer, command-line arguments, INI file. So if you set HKEY_LOCAL_MACHINESoftwareFileOptimizerDoNotUseRecycleBin to “true” it will take precedence in all cases.

Why FileOptimizer is not using all my CPU cores?
Making FileOptimizer a multithreaded application involves a major rewrite of it. Basically, GUI can only run in the main thread, which implies a big reengineering. Some progress has been done since 2 years ago, but it is getting more and more difficult as its codebase enlarges. Also having plugins such as ECT or mp3packer which are already multithreaded, makes less sense to continue the task.

How to translate FileOptimizer in your own language?
Since FileOptimizer 12, user inteface is multilanguage/multilocale capabled. You can translate it to your own language.

1) Execute FileOptimizer with the /SAVELANGUAGE command-line argument, like this: D:PROYECTOSFileOptimizerFileOptimizer64.exe /savelanguage

2) Browse all secondary windows (Options, About, Information, …) and keep using FO for some time.

3) If everything went OK because there was write permissions on FileOptimizer folder, when you close it a file called 1033.po will be available. This file will contain all english strings that have been presented.

4) Make a copy of 1033.po, and name it as the language (LANGID) or locale (LCID) you will be translating to. You can use reference table available here: https://msdn.microsoft.com/library/windows/desktop/dd318693(v=vs.14.0).aspx

For example, if you want to translate it to “Spanish Modern Sort (ES)” name it 3082.po (3082 is 0×0C0A in decimal). If you want to translate it to “Spanish Dominican Republic (DO)” name it 7178.po (7178 is 1C0A in decimal). In the case you want to translate to a language instead of a locale, for instance to “Spanish (es)” for all countries, you should name it 10.po (10 is 0A in decimal).

5) Translate the contents of the copied PO file. It is a text file where for each msgid containing the original english text, you have an empty msgstr with the translation. You can use any text editor like notepad, or dedicated PO utilities, even if they are cloud based (Online PO Editor).

6) When finished, put your new PO file together with FileOptimizer32.exe or FileOptimizer64.exe. If you current system locale is set to the primary language or locale you translated to, FileOptimizer will read it, and translate all the texts according to your translation. Double check nothing is broken, no texts are missing, and lengths is enought to fit on all items in screen.

7) You are now done. You can erase 1033.po. Please post your translation onto https://sourceforge.net/p/nikkhokkho/discussion/fileoptimizer/ if you will it to be officially included in FileOptimizer.

Why there is a donate button being the program free?
FileOptimizer is free either for personal and commercial usage. I have spent hundreds of hours in creating, developing, researching, supporting, testing and maintaining it, so if you consider a donation is worth my effort, it is highly appreciated, but not mandatory. Program will work as the full version without any limitations, no matter if you have donated or not.

How much should I donate?
There is no minimum nor maximum in the donations. Simply consider the benefit it is reporting to you, and how the compensation you will give to the future of FileOptimizer should be. Donations of even 1 euro, are welcome the same as 1000 euro.

What if I have problems donating?
Current donation platform is managed by Paypal.Me, which is fast and safe. Unfortunately it is not supported in all countries and currencies, so you can try the old Paypal platform here.

Can I donate more than once?
Sure, you can donate more than one time. Indeed, I am spending time on FileOptimizer more than once, so it is fair. You can choose to do it after a new version, after a major one, or as you can afford.

Where is latest source code?
Source code for releases is available in the Download section above.
Latest deveolpment code is available in the SVN repository.

Where can I send suggestions, comments and bug reports?
Better place for easily followup comments, suggestions and bug reports is on the Discussion page at Sourceforge.

How can I contribute the project?
If you want to contribute and actively participate in the evolution of FileOptimizer, your help is highly appreciated.
You can donate money, or send patches and improvements in the source code, or even send suggestions, or bug reports to plugin developers. Also communication in other websites such as software portals or Wikipedia is welcome.

How can I get FileOptimizer support?
I am receiving lots of support request. I will not guarantee support nor answers to users that are not engaged in the FileOptimizer community. Either by contributing in user to user support, expanding its popularity, donating via Paypal, or reporting issues to plugin developers.

Why is FileOptimizer showing me advertisements?
Some users are not able to donate and asked for other approaches to support FileOptimizer. This is the reason why it displays ads. Ads are placed to not be intrusive, and if desired can easily be disabled using Options -> Appearance -> Hide ads.

If you have donated, you can enter your email/name for the donation in Options -> Appearance -> Donator and all reminder will disappear.

What if I have a question, and do not want to contribute to the community?
Even if that is not fair, of course you can solve your questions. Try to ask to another user, look at the source code, and take a look to the FileOptimizer website and documentation.

Why is FileOptimizer available in warez portals?
Recently I have found some Torrent sites, as well as warez portals offering repackaged FileOptimizer distributions.
Be warned that those sites usually include malware in their packages, mostly adware to give them incomes with no effort nor credit to the original authors, so if you opt to get elsewhere, you are not only underestimating my work, but also putting your PC in risk.
Obviously, the author, me, has no relationship with those sites, and what is more important, I am not seeing any advantage on pirating a software which is already free.
Remember that FileOptimizer is free, and open source, being always available as direct download from its official page: https://nikkhokkho.sourceforge.io/static.php?page=FileOptimizer

Can you give more details on how FileOptimizer works?
As said before, FileOptimizer is only a frontend for external command-line applications, called plugins. Those plugins are the ones which does the hard part, and the ones deserving creting. This is why usually optimization bugs happen in plugins, instead of in FileOptimizer side.
If you need more details about the internals, please take a look at the links above with the official sites for them, where you could get lots of technical details.
