SquishyFile

SquishyFile is a free online video compression tool that runs entirely in your browser, allowing you to compress videos without uploading them. It supports a wide range of formats including MP4, MOV, MKV, AVI, and WebM. The compression happens locally on your device, preserving privacy and eliminating upload queues. SquishyFile lets you pick predefined compression levels or specify an exact target file size to fit various platform limits like email or social media.

The tool uses your browser's built-in WebCodecs encoder for modern formats and falls back to a WebAssembly version of FFmpeg for older or less common formats. This dual-engine approach ensures fast and efficient compression on most devices. SquishyFile also offers batch compression with no file size caps or watermarks, making it ideal for various use cases from sharing on WhatsApp to preparing videos for Discord or LinkedIn.
