Is my video uploaded to a server?

No — compression runs in your browser with FFmpeg WebAssembly. Your video never leaves your device, no matter how personal it is.

How much smaller will my video get?

Typically 50–90% smaller depending on the level. Phone recordings compress dramatically because they use inefficient high bitrates.

Is there a watermark or length limit?

No watermark, files up to 500MB. Longer videos simply take longer since your own device does the work.

What formats can I compress?

MP4, MOV, WebM, AVI, MKV — output is a universally compatible MP4 (H.264).

Shrink videos 50–90% for WhatsApp, email and the web — processed entirely in your browser. Your videos never leave your device.

Why your videos are so large

Phones record at very high bitrates for editing headroom — a 1-minute iPhone clip can be 150MB. Re-encoding with modern settings keeps the video looking nearly identical at a fraction of the size. This tool does it with FFmpeg running in your browser: no upload queue, no watermark, no server ever seeing your video.

WhatsApp: 64MB status limit — Balanced + 720p handles most clips
Email: 25MB attachment limits — Strong + 480p for longer videos
Websites: smaller videos = faster pages and better SEO
Storage: archive old recordings at 1/5 the space
