Free YouTube Shorts Video Editor

Edit YouTube Shorts in a free, no-watermark browser editor — the canvas opens vertical 9:16, the exact shape YouTube Shorts uses, so you're ready to go. Trim clips, add an AI voiceover, auto-captions and royalty-free music, then export a clean MP4. No account, and your video never leaves your device.

Made for YouTube Shorts

Open the editor from this page and the canvas is already set to vertical 9:16 — no settings to fiddle with. Drop in any footage and resize it to fit or fill (drag, pinch and zoom on the canvas), and use the safe-zone overlay to keep captions and text clear of the YouTube Shorts interface. Export an MP4 with no watermark.

Everything you need, free
