Trim video · frame-accurate · zero watermark

Trim Video Online Two markers. One trim.

Most "trim video online" tools want you to upload your file to their server, watch a render queue, then download a watermarked output. Morph runs FFmpeg.wasm in your browser tab — stream-copy the trimmed segment when possible (no re-encode, no quality loss), or re-encode when needed. Frame-accurate I/O markers on a scrubbing timeline, MP4/MOV/WebM/MKV in and out, no upload, no watermark. Free for everything that runs on your device; AI is paid in credits.

TRIM

Frame-accurate I/O markers — set start, set end, ship.

Scrub the timeline, drop in/out markers (I and O keys), preview the trimmed segment, export. The whole interaction takes ten seconds for a clean cut.

What it actually does

02
LOSSLESS

Stream-copy when possible

If the trim doesn't require re-encoding, Morph stream-copies the original codec data — instant export, zero quality loss.

03
FORMATS

MP4, MOV, WebM, MKV, AVI

Same format in, same format out. Or transcode if you want.

04
CLEAN

Zero watermark

Nothing branded onto your export.

How it works

  1. Open morph.cool/video-editor. Drop an MP4, MOV, WebM, MKV, or AVI.
  2. Scrub to the start. Press I to set the in-point. Scrub to the end. Press O for out.
  3. Preview the trim. Adjust frame-by-frame with arrow keys if needed.
  4. Export. Stream-copy is the default (instant); switch to re-encode for cross-format trim.
  5. The trimmed file lands in your downloads. No upload happened.

Frequently asked

Will my video be uploaded?

No. FFmpeg.wasm runs in your browser tab.

Will it have a watermark?

No.

What's the file size limit?

A few hundred megabytes comfortably. The browser is the bottleneck, not Morph.

Frame-accurate?

Yes. Stream-copy aligns to keyframes; full re-encode is frame-perfect to a single frame.
