Worked example
Three phone clips from a trip (20, 35 and 15 seconds) are placed in order, trimmed, joined with 0.6-second crossfades and exported as one MP4 of about 68 seconds, ready to share.

Frequently asked questions
Can I merge videos of different sizes?
Yes. Clips are fitted to one output frame size, with blurred or solid bars when their shapes differ, so the result plays smoothly.
Does merging reduce quality?
The merged video is re-encoded to one consistent format, which is lossy but visually close at the default settings.
Is there a size limit?
Each clip is limited to 250 MB because the browser holds it in memory. The first export downloads about 32 MB of processing code.
Can I add music or text?
Yes. The same editor can add a music track, a text banner and subtitles.
Is my video uploaded?
No. Everything is processed in your browser.
