Free YouTube Video Editor

Edit YouTube videos in a free, no-watermark browser editor — the canvas opens landscape 16:9, the exact shape YouTube 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

Open the editor from this page and the canvas is already set to landscape 16:9 — 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 interface. Export an MP4 with no watermark.

Everything you need, free

• Trim & arrange clips on a simple timeline.
• AI voiceover — type a script and pick a natural voice.
• Auto-captions with word-exact timing (Hormozi, Karaoke and more styles).
• Royalty-free music from the built-in library.
• Add text & overlays, then export — no watermark, no sign-up.
