Video editor
Drop a few clips, cut out the boring bits, fade between them, zoom in where it matters, save.
Runs in your browser. Nothing you paste or drop here is uploaded anywhere.
Select a clip, the diamond between two clips (transition) or a zoom to change it. Double-click the zoom track to add a zoom there.

Timing
Save as
Plays everywhere: phones, chats, other editors. With sound.
Smaller than MP4 at the same quality, with sound. Some older iPhones won’t play it.
No sound, loops forever, works anywhere an image does (chats, docs, READMEs). Files grow fast, so keep it short and narrow.
Keyboard (click the preview or timeline first): Space play/pause, ← → one frame (Shift one second), S cut, Z zoom, Delete remove, Ctrl/⌘ Z undo, Ctrl/⌘ + wheel over the timeline to zoom it.
No clips yet. Drop some above.
How to use it
- Drop one or more video files on the box, or click it to choose them. Each one lands on the timeline after the last.
- Move the playhead (click the ruler or press ← →) and press Cut or S to split a clip. Select the piece you don’t want and press Delete.
- Drag a clip’s edges to trim it, or drag the middle to move it before or after another clip.
- Click the diamond between two clips and pick Crossfade or Fade to black.
- Press Zoom or Z to add a zoom at the playhead, stretch it on the zoom track, then click the preview where it should zoom in.
- Press + beside the timeline to add a track above the main one, then drag a clip up onto it: it plays over the clips below, at the time you drop it. The eye next to a track hides it in the preview and the export.
- For slow motion or a speed-up, cut out the part, select it and pick a Speed: 0.25× to 4×. Sound keeps its pitch.
- Pick a format under Save as (MP4, WebM or GIF) and press Export. The editor plays the whole video once while it records, then saves the file.
What it does
Everything happens in this tab: the clips are read straight from your disk, drawn on a <canvas> and recorded with the browser’s own MediaRecorder. Nothing is uploaded, so it is fine for family videos and screen recordings of things you would rather keep to yourself.
Export runs in real time: a 3-minute edit takes about 3 minutes to save. Keep the tab in front while it records, because browsers slow down hidden tabs and the video would stutter.
You get MP4 (H.264) where the browser can record it, which is current Chrome, Edge and Safari, and WebM in Firefox. The frame matches your first clip, up to 1920 pixels on the long side, or you can force 16:9, 9:16 or 1:1. Clips with a different shape get black bars instead of being stretched.
A zoom scales the whole picture around the point you clicked, easing in at the start and out at the end, the way screen-recording tools zoom on a cursor. Transitions overlap the two clips by their length, so a crossfade makes the video a little shorter.
It is deliberately simple: one video track, the clips’ own sound, no titles or music track. For a quick “trim this, join that, zoom on the bug” it saves you installing anything.
Questions
Does this upload my video?
No. The files are opened from your disk as local URLs, edited and recorded inside the tab, and the result is saved straight to your downloads. You can go offline after the page loads.
Why does export take as long as the video?
The browser has no fast built-in “render this edit” function, so the editor plays the timeline and records the screen of the canvas as it goes, sound included. Faster-than-real-time export needs a full encoder library, which is a lot to download for a quick cut.
Which file formats can I open?
Whatever your browser can play: MP4 (H.264) and WebM everywhere, MOV from iPhones in Safari and Chrome, HEVC/H.265 only where the system has the codec. If a file won’t open here, it won’t play in a browser tab either.
Can I make a vertical video for Reels, Shorts or TikTok?
Yes. Set Frame to 9:16. Vertical phone clips fill it; horizontal ones get bars, and a zoom on the important part fixes that.
How do I turn a video into a GIF?
Drop the video, cut it down to the part you want, pick GIF under Save as, set the width and frames per second, and press Export. GIFs have no sound and get big fast: 5 seconds at 480 px and 12 frames/s is around 1 MB, more for noisy footage. Zooms, cuts and transitions end up in the GIF too.
Is the quality worse than the original?
A little, as with any re-encode. The recording is made at about 8 Mbit/s, which is fine for 1080p. The frame size never goes above 1920 pixels, so a 4K clip comes out as 1080p.
