5 toolsOpen Compressor is a free online file compression platform that prioritizes your privacy. Most compression tasks are processed directly in your browser — your files never leave your device. For larger or more complex files, our secure servers handle the processing with automatic deletion after completion.
Our client-side compression uses modern browser APIs (Compression Streams, WebAssembly) for near-native speed. Server-side processing leverages industry-standard tools like FFmpeg, ImageMagick, and Ghostscript for maximum compatibility.
From images (JPEG, PNG, WebP, SVG, GIF) to videos (MP4, AVI, MOV, MKV), audio (MP3, WAV, FLAC, AAC), PDF documents, and archives (ZIP, RAR, TAR, 7Z) — Open Compressor handles them all.
