About ImgCompress
A free, browser-only image compressor built by People in the Lab.
Why we built this
We kept running into the same problem with other "free" image compressors: hard caps on how many files you could process, photos uploaded to someone else's server before you could even see the result, and so many ads around the drop zone that the tool itself was hard to find. ImgCompress exists because we wanted a compressor we'd actually want to use ourselves — no upload, no file-count limit, no sign-up wall.
How it works
ImgCompress runs entirely inside your web browser using the Canvas API and WebAssembly. When you drop in a JPG, PNG, WebP, or HEIC file, the decoding, resizing, quality adjustment, and format conversion all happen on your own device. Nothing is ever sent to a server — you can confirm this yourself by opening your browser's developer tools and watching the Network tab while you compress an image.
Who's behind it
ImgCompress is built and maintained by People in the Lab, a small software studio that builds and ships practical tools the way we'd want to use them. This site is one of our ongoing projects, actively maintained and improved based on real user feedback.
What we stand for
Free to use, no account required, no watermarks, and no limit on how many images you compress. The only way this site is funded is through the ads you see on the page — we don't sell data, because we never collect any image data to sell in the first place.
