Google Chrome Labs has just revealed Squoosh, an in-browser image compression tool that can use non-browser image codecs to compress images without much loss in quality. The app can also be run offline after it is loaded in a browser at least once. Squoosh is aimed at web designers that hope to reduce web page load times by using compressed images.

For webmasters and web developers, managing the file size of content on a web page has been a constant challenge. As images get more detailed, file sizes increase and web pages can take longer to load. Google Chrome Labs may have a tool to alleviate some of that pressure: Squoosh.

Squoosh is an in-browser image compression application designed to “make images smaller using best-in-class codecs,” according to the app’s GitHub page. Squoosh is fully open-source, meaning the code is widely available to the public. Squoosh is able to use codecs not typically available to web browsers to compress images into a more manageable file size, and it does all this within almost any major web browser of your choice.

After loading Squoosh, the app will cache itself into your web browser. In other words, after you’ve loaded Squoosh the first time, it can work completely offline.

So what does Squoosh do? Its primary purpose is compressing images without a noticeable loss in quality. It achieves this goal remarkably well; using the sample “large” image provided on the Squoosh website, the app is able to compress a 2.79 MB image down to just 861 KB without a noticeable shift in quality. The app includes a comparison slider so you can see what your image will look like after its compressed. In our testing (Large photo, default settings), we noticed a slight loss in color detail with a somewhat duller overall image. These changes are only noticeable under close scrutiny; at a passing glance, the images are identical, despite the compressed file being 69% smaller (2.79 MB vs 861 kB).

Squoosh is free to use at squoosh.app. The code is freely available at Google Chrome Labs’ GitHub page.

I've been a "tech-head" my entire life. After graduating college with a degree in Mathematics, I worked in finance and banking a few years before taking a job as a Systems Analyst for my local school district. I started working with Notebookcheck in October of 2016 and have enjoyed writing news articles and notebook reviews. My areas of interest include the business side of technology, retro gaming, Linux, and innovative gadgets. When I'm not hunched over an electronic device or writing code for a new database, I'm either outside with my family, playing a decade-old video game, or sitting behind a drum set.
