About File Compressor
File Compressor is a free set of tools for making JPG, PNG and WebP images smaller. It is built around three rules: every tool listed actually works, results show measured sizes rather than estimates, and files are deleted automatically.
It is run by LoverPDF, who also runs our sister site Video Compressor for videos. PDF compression is on LoverPDF. Both sites use the same server in Europe and the same privacy rules.
How it works
Images are processed with libvips (via sharp) and an optimized JPEG encoder. Each file runs in an isolated worker with time limits, and every output is checked before it's offered for download. Read more in How compression works.
