MP4 editor · browser-native NLE · zero upload

MP4 Editor Online The timeline. In your tab.

Most MP4 editors send your file to a server, render in their cloud, then watermark the output unless you upgrade. Morph runs FFmpeg.wasm directly in your browser tab — the same engine that powers the desktop render pipelines, just running locally. Trim, cut, color grade, speed ramp, LUT, GIF export, scopes, command palette — a real NLE, in a tab. Free for everything that runs on your device; AI is paid in credits.

01
EDIT

Trim, cut, reorder, speed ramp — multi-clip timeline with magnetic snapping.

Drop your MP4. Cut at the playhead with Cmd+K. Drag to reorder. Speed ramp with keyframes. Multi-track media library, properties panel, transport controls. The whole NLE feel, in a tab.

Will the export have a watermark?

No. Morph never adds watermarks.

What's the file size limit?

A few hundred megabytes comfortably on desktop; mobile varies by device memory.

Yes. Video tracks for video/image/text, audio tracks for audio. Cross-track drag enforces compatibility.
