Frequently asked questions
What resolutions can I choose?
1080p (Full HD), 720p (HD) or 480p (SD). The tool scales your video down to the chosen height while keeping the original aspect ratio — nothing gets stretched or cropped.
Does my video leave my device?
Never. The resize (a WebAssembly build of FFmpeg, loaded unmodified from a CDN) runs entirely on your device. Your file is processed locally and is never uploaded to any server.
Is resizing video really free? Any watermark?
Yes — 100% free with no signup and no watermark, and there are no limits on how many videos you resize (files up to 500 MB are supported). Your video downloads straight to your device, ready to post.
How much smaller does the file get?
Roughly proportional to the pixels: 4K → 1080p usually cuts 60–75% of the file size, and 1080p → 720p roughly halves it. Audio is copied untouched, so the sound stays identical.
My video is already 720p — what happens?
The tool detects that and tells you no resize is needed, so you don’t waste time re-encoding a video that’s already the right size.
Which video formats can I upload?
MP4, WebM, MOV, MKV and most common video formats work. Files up to 500 MB are supported.
