Batch Image Optimizer

Welcome to the Free Image Optimizer! Using this free online service, you can resize, compress and optimize your image files. Using the service is as easy as clicking of button! Optimized images are better! They are more suitable for web pages, email attachments, or even storage on your disk. Give it a try now! Lossy Compression. Lossy is the best option for most users. The images processed with Lossy algorithms are the smallest optimized images you can get. So, if the speed of your site is paramount and you want the best balance between optimization and picture quality, we recommend you to continue to use Lossy optimization. The ability to batch resize multiple images in Windows seems like it should be something the operating system itself, or its built-in tools, could offer in a user-friendly way. Until that happens, Image Resizer for Windows is an excellent option that cleanly integrates into the File Explorer interface and offers users powerful resizing. Image optimization plays an important role in SEO. There are many compress image Mac solutions that know how to work with bitmap graphics. It is a widespread belief, that in order to prepare graphics for the web, you should use only editors focused on this because only then you can get the most optimized images that will not create an excessive.

There are many types of different image formats and some of those most commonly found on the Internet are JPEG, GIF, BMP, TIFF and PNG. Each image format has its own purpose such as GIF is used for animated images, JPEG for high quality photos which automatically gets degraded after each save or even a resize, while our favorite PNG is best used on small and transparent pictures. Another huge advantage in PNG files is they're lossless meaning you can compress PNG's without losing quality.

Automate your batch image processing without programing a simple line of code. Automatically optimize your images for web with no technical headaches or specific codecs knowledge. Convert and compress images for web. Select the image format to perfectly optimie your images and photos for web.

You can easily find many tools on the Internet to compress PNG files but most, if not all of them produce different file sizes due to the algorithm unless they are using the same library/technology. Reducing the image file size to the maximum helps to save bandwidth cost, time to download and even achieving a higher Google PageSpeed score because 'optimize images' is one of the priorities. In this article we've put 13 free PNG compressor tools (online, command line, desktop) to the test to find the one that produces the smallest file size.

To view the compression test results and summary, they can be found on page 2.

Command Line Tools

1. advpng

advpng is part of AdvanceCOMP that contains multiple free utilities to recompress PNG, ZIP, MNG and GZ files. advpng hasn't been updated since 2005 but the compression speed and results will surprise you. Older machines with slower hardware specifications takes slightly longer to process while the newer multi-core CPU takes only a second to produce amazing results.

advpng maximum compression command:

advpng.exe -z4 file.png

Download AdvanceCOMP

2. OptiPNG

OptiPNG is another open source command line PNG compressor that supports Windows and Linux operating system. Both stable and development versions are available to download. Do take note that the maximum command line compression for the stable and development versions are slightly different. The highest level of compression for the OptiPNG stable is -o7 while the development is only -o6. If you try to force -o7 on the development build, you will still get the same file size as -o6.

OptiPNG stable maximum compression command:

optipng.exe -o7 file.png

OptiPNG development maximum compression command:

optipng-hg-latest-win32 -o6 file.png

Download OptiPNG

3. Pngcrush

Pngcrush is also a commandline application that attempts to optimize PNG images by trying out different compression levels and PNG filter methods. If you use the -brute switch, Pngcrush will test the image with 148 methods to find the one that gives the best compression.

Pngcrush maximum compression command:

Pngcrush.exe -brute file.png output.png

Download Pngcrush

4. PngOptimizerCL

PngOptimizer comes with a simple graphical user interface program and all you need to do is drag the images that you want to compress to the program's window, and also a command line application that runs in command prompt. Other than cleaning up wrong/useless information on PNG to reduce the file size, it can also support animated PNG format (apng) which is still uncommon today. You can either specify the exact file name to optimize or can even use the asterisk character as a wildcard.

PngOptimizerCL maximum compression command:

PngOptimizerCL.exe -file:'file.png'

Unlike most of the command line PNG optimizers, PNGOUT is not open source because the compression algorithm is incorporated into their commercial GUI version called PNGOUTWin that has batch processing and multi-core CPU support. Although it is not open source, you can find pre-compiled binaries for Windows, Linux, BSD and Mac OS X. PNGOUT is one of the easiest to use because by default it uses the highest Xtreme compression algorithm for optimization without specifying an additional command line switch.

PNGOUT maximum compression command:

pngout.exe file.png

Download PNGOUT

6. ScriptPNG

Batch Image Optimizer Windows 10

ScriptPNG is actually a batch file that is capable of running up to 10 PNG compressors to optimize an image file. Selecting the ultra brute option number 9 will use the maximum compression options to produce the smallest file size but taking more time to complete the optimization process. All you need to do is drag and drop your PNG files to the program from Explorer and followed by selecting one of the 9 available options.

7. TruePNG

TruePNG only supports PNG files unlike some of the PNG compressors above that can attempt to convert other image formats such as JPEG and GIF into PNG if it is able to achieve a smaller file size.

TruePNG maximum compression command:

TruePNG.exe input.png /o max

8. PNGGauntlet

PNGGauntlet is actually a front-end tool that uses 3 different PNG optimizers (PNGOUT, OptiPNG, and DeflOpt) to further compress PNG files instead of normally using just 1. The usage of 3 compressors does increase the time taken to compress the PNG files but definitely yields a smaller file size. A nice feature found in PNGGauntlet is the ability to automatically queue multiple files for batch processing. The default options from the Tools menu are already best (maximum) settings unless you want to preserve the PNG metadata, use grayscale color type and etc. Microsoft .NET Framework 4 is required to run.
