We test compression tools on a fixed set of sample files (images, PDFs, video) with documented settings.
Results are reproducible — the sample set and scripts are public on GitHub.
Private. Files are processed in your browser. Nothing is uploaded.
Free, unlimited. No account, no watermark, no daily caps.
