RedPanda Compress

RedPanda Compress is a free online video compressor built on ffmpeg.wasm and WebAssembly multi-threading. All compression happens locally in the browser, so videos are never uploaded to a server - which makes it fast, private and safe. Users pick a target file size and the tool compresses MP4, MOV or WebM files up to 2GB while preserving the best possible visual quality. It works on macOS, Windows, iPhone and Android, supports more than 20 interface languages, and requires no registration.

There are no watermarks and no usage limits. The site also offers free in-browser PDF compression and HEIC to JPG conversion. Typical use cases include shrinking videos for email attachments, Discord, WhatsApp, course uploads and web publishing.
