Lightning Video Shrinker
Privacy-first video compression that runs entirely in your browser — nothing is ever uploaded anywhere.
Why It Exists
Most video compressors require you to upload your files to a server, sacrificing privacy and speed. This tool uses FFmpeg compiled to WebAssembly so everything happens locally on your device.
What to Use It For
Shrink videos to fit Discord's 10 MB limit, email attachments, Slack or Teams messages, social media uploads, or just to save storage space on your device.
Who Needs It
Anyone who records screen captures, phone videos, or gameplay clips and needs them smaller — without installing software or trusting a third-party server with their files.
