Loseless PNG, JPEG and GIF optimization / compression tool for Windows.

[just a worm]

Could you please give some information about the png-optimization tools? In the directory there are the files with their names but I have no idea what the tools do.

For example I am looking for a tool that recursivly goes through a directory and decreases the size of all png files and doesn't touch any other/non-png file. I think I have already seen it here on encode.su but I don't know it's name anymore.

After reading readme.md (section Tools used) use Google to search about those tools.

Please compile the program for windows

Good day! Prompt, please, the program for optimizing JPEG lossy?
I found:
https://github.com/danielgtaylor/jpeg-archive
https://github.com/rflynn/imgmin
https://github.com/tjko/jpegoptim

Prompt, a metric for comparing two images. Watched MSU Quality Measurement Tool, but can't understand which metrics best suited for visual change in image quality?

I might be misunderstanding this, but can't you do this with any command line .png optimizer like .e.g PNGout?

for /r %r in (*.png) do pngout.exe "%r"

Thats how i do it, except i call my batch file that runes multiple optimizations on a .png file. sometime my pc wwill chunk for week on an entire tree structure with .png files all over the place

Tell me, please, how to compile under windows the following projects
https://github.com/rflynn/imgmin

[Skymmer]

Well, you can try to use makefile files from every project.
At first you need to get some GCC distro. For example MinGW-w64. In case you're confused which version to use - grab the x86-posix-dwarf from here.
Now create batch file like this:

rem set path to bin folder of mingw
set path=d:\MingW\Mingw64\32-win32-dw\bin
mingw32-make.exe -f makefile
pause
exit

Place this batch to the root of the desired source and run it.
Probably you'll get nothing just out-of-the-box. The reason is that there are some dependencies which you need to get and probably makefiles are not error-free so you need to edit them, like for example changing @SET_MAKE@ to SET_MAKE = @SET_MAKE@ for JpegOptim. And even if you made everything correctly there can be other unpredictable errors.

Another method is to use MSYS2 which has some native Linux tools ported to Win so it can do configure\make sequence.
And another method is to use cross-compiler directly from Linux but I have no experience here so I can't say for sure.
Anyway, good luck in your efforts.

[lorents17]

If you don't mind, please make a compilation of the project
https://github.com/rflynn/imgmin
I would be very grateful

Back when I first saw imgmin, I gave up trying it because there was no obvious way to compile it on Windows.

Yesterday I took another look, and got it to at least compile with mingw-w64. The attached archive contains some patches and build instructions, along with a static Win64 compile of imgmin 1.1.

Please note this is more or less just a proof of concept that it is possible to compile it, and it may not work like it is supposed to. Also, I had to remove the PNG handling, so it only works on JPEG files.

[GOZARCK]

Thanks jibz for compile.
this is my bat file. Compress each jpg file and then create new file processed "namefile_proc.jpg" and delete the original.

@echo off
title Imgmin
::
for /r . %%T IN (*.jpg) do (

@imgmin "%%T" "%%~pT%%~nT_proc.jpg"

del "%%T"
)
pause

[lorents17]

jibz Thank you very much!

If the value zs=3 (zlib), it is better to use --zopfli-iter=25, for best compression. Who knows why this is happening?

[lorents17]

And further

This image pngout shakes much better zopfli. How can I fix it?

good evening!
Tell me, has anyone seen advancecomp with an updated version of 7-zip deflate? Or another program with functions advdef?

ibdeflate has good extent of compression and high speed of work. There was an idea to create the application on compression of PNG on the basis of libdeflate (on similarity of advdef).
I will be grateful if somebody writes such application on the basis of libdeflate.dll.

for %%i in (PNG\*) do (
    krzydefc --gzipname "%%i"
    7za x "%%i.gz"
    gzip -12 "%%~dpni"
    krzydefc --png"%%~i" "%%~dpni.gz"
    del "%%i.gz"
    del "%%~dpni.gz"
    move /y "%%~dpni.gz.png" "%%i"
)

And

Please, help to compile optipng with support of masmx86.
