Frequently asked questions
How much smaller will my video get?
Phone videos in 1080p or 4K saved at 720p · Medium usually end up around 10–30% of the original size. Type a target size in MB if you need an exact limit.
How do I get under an email attachment limit?
Type 24 in Target size for a typical 25 MB limit. Short videos can stay at 720p; for longer ones choose 480p or trim the part you need.
Will the quality drop a lot?
720p · Medium looks sharp on phone screens. Choose 1080p · High for big screens. Quality never gets better than the original.
Do iPhone MOV videos work?
Yes. iPhone MOV (HEVC) files can be added and are saved as MP4 that plays anywhere. If your browser can't read HEVC the preview may not show — use the latest Chrome, Edge or Safari.
Is my video uploaded?
No. The video is read and saved again entirely inside this browser on your device. It is never sent anywhere.
