About filecompressor.app

Free, private, browser-based file compression tools.

filecompressor.app is a free online file compression suite launched in 2026. We help everyone — students, creators, office workers, and developers — shrink files without uploading them to a server. Every compressor runs entirely in your browser using WebAssembly and Web Workers, so your files never leave your device. That means stronger privacy than upload-based tools, no sign-up, no watermarks, and no file size limits. We support images (JPG, PNG, WebP, AVIF, HEIC, GIF, SVG), documents (PDF, DOCX, PPTX, XLSX, EPUB), video and audio (MP4, MOV, MP3), and archives (ZIP, RAR), plus target-size compression, batch processing, and a developer API.

Our Mission

Our mission is to make file compression free, private, and effortless for everyone. We believe your files should never have to leave your device just to be made smaller, so we build every tool to run locally in your browser — no uploads, no tracking, no paywalls. We commit to keeping filecompressor.app free forever and to expanding our toolset as new formats and use cases emerge.

filecompressor.app was launched in 2026. All file processing happens on-device via WebAssembly and Web Workers — no files are uploaded to any server. Last updated: 2026-07-27.
