Questions and answers
Is my video uploaded?
No. Compression runs in your browser with your device’s own video encoder (WebCodecs). The file never leaves your phone or computer.
How small can a video get?
It depends on the length. A 1-minute 1080p video fits in about 10 MB with good quality. For long videos, very small sizes look blurry; lowering the resolution to 720p or 480p helps.
Which browsers work?
Recent Chrome, Edge and Safari (on iPhone and Mac) and Firefox on computers. Long 4K videos need a lot of memory; if it fails, choose a lower resolution.
Is there a watermark?
No. You get a normal MP4 (H.264 video, AAC sound) that plays on any phone, computer and app.
