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.
