Are my videos uploaded to a server?
No. Everything runs inside your browser — reading, trimming, merging and exporting. Your files are never sent to us and never stored.
How many videos can I merge?
There is no fixed limit. Add as many as you like on the same timeline; they are merged in the order you choose and you can drag them to reorder.
Can I place images between clips?
Yes. Images sit on the same video track with a default duration of 5 seconds, and you can drag their edge to make them longer or shorter.
Can I add more than one audio file?
Yes. Press + next to the audio track to add several files that play one after another. You can trim them, reorder them, and set the video and music levels separately.
What does “Freeze frame” do?
It captures the frame under the playhead, splits the clip there, and inserts that frame as a still image between the two halves — handy for holding a moment inside the video.
An iPhone video will not open in the tool — why, and how do I fix it?
iPhones record in HEVC (H.265) inside a MOV file by default, and Chrome, Edge and Firefox cannot decode that codec for licensing reasons — the tool reads video inside your browser, so it cannot open what the browser refuses. Two fixes: (1) On the iPhone go to Settings → Camera → Formats and pick “Most Compatible”; it will then record H.264, which every browser supports. (2) For an existing video, send it to yourself on WhatsApp or Telegram and use the received copy — those apps convert it to H.264 automatically. It also helps to turn off “HDR Video” under Settings → Camera → Record Video.
Which browsers are supported?
The tool works best on Chrome and Edge, on desktop and Android. Some iPhone codecs (HEVC and ProRes) may not be readable by the browser.
Does exporting take long?
Exporting runs in real time: a one-minute video takes about a minute. Keep the tab open and visible until it finishes.
