It also includes the ability to simply compress PNG and WebP files using either lossy or lossless methods. A powerful feature in IrfanView is the batch editor that can edit multiple files with tons of different settings.

IrfanView is one of the most popular and best image viewers for Windows and has been for many years. The highest level of compression is the “very Slow” 07 although the default is 02. In addition to directly compressing a PNG, it can also convert BMP, GIF, PNM, and TIFF to compressed PNG. OptiPNG is another open source command line PNG compressor that supports Windows and Linux. This is a potential saver of time and downloading multiple images just to see what setting works best.

It is useful that Squoosh shows what the changes to the compression settings do to the size of the image file before you download it. For WebP, check the Lossless box, slide Effort to 9, and Slight loss to 0 (it appears to perform some light lossy compression). For OxiPNG, just slide the Effort slider to 3 to hopefully get a few more KB savings over the default of 2. Besides JPEG and AVIF, Squoosh also supports compressing PNG and WebP using both lossy and lossless methods.Īfter dropping an image onto the browser window or loading it manually, select OxiPNG or WebP from either the left or the right dropdown menu. Essentially, GoogleChromeLabs is a bunch of side projects created by the Google Chrome developers. It might come as a surprise to some, but Squoosh is actually an online file compressor and basic image editor from GoogleChromeLabs.

Versions are open source and available for Windows, DOS, Mac OS, and Linux. The maximum “Insane” compression mode can be a bit slower on older machines but modern computers won’t see a compression time of more than a few seconds for a moderate size image. After a gap of four years, AdvanceCOMP had a new release in 2022 although it was only compatibility fixes.

If you just supply a folder to the command, it will process and compress all files in that folder.ĭownload ECT (Efficient Compression Tool)Īdvpng is part of AdvanceCOMP that contains multiple free utilities to recompress Zip archives, PNG, MNG, and GZ files.

ECT is open source and cross platform with a Mac OS version available.
Also, it’s the most up to date tool here with the latest release only a couple of days old. Firstly, it can compress JPEG, Zip, and GZip files in addition to PNG. There are a couple of things that make ECT a potentially useful tool. It’s also considered experimental so could be a bit buggy.Ģ. All you have to do is enable Extreme compression from the dropdown and uncheck Lossy Compression in the Settings to get the same output as Pingo. Pinga is a GUI interface for Pingo but is limited to just PNG and JPG compression. In addition to those two formats, Pingo is also able to compress JPG and APNG files along with a simple ability to resize images, convert to greyscale, enhance details, and remove transparency. Pingo is interesting because it’s one of the few command line tools that can compress both PNG and WebP images using lossless (and lossy) compression. The maximum available compression setting is listed and used for each program or service. Popular converters like the online TinyPNG will therefore be missing.
Note that we are not including options that don’t allow lossless compression on both PNG and WebP. It’s up to you to decide which format best suits your needs. This is not a PNG vs WebP article as it’s about which PNG tools compress a PNG better and which WebP tools compress WebP better. In this article, we look at 17 free PNG and WebP lossless compressor tools (online, command line, desktop GUI) and also find which ones produce the smallest file sizes while preserving image quality. Reducing the image file size as much as possible helps to save bandwidth cost, reduce time to download, and even achieve a higher Google PageSpeed score because “optimize images” is one of the priorities. You can easily find many tools on the Internet to compress image files but most, if not all of them produce different file sizes. The newer WebP is dual role because you can compress images with either lossless or lossy compression but it’s a bit less compatible than JPEG and PNG. PNG is good on smaller and transparent pictures because it’s lossless and you don’t lose quality. The GIF image format is commonly used for short animated images while JPEG is for higher quality photos using lossy compression to reduce file sizes.
