Trim MP4 videos online, free
Every recording has dead air at the edges — the finger over the lens, the "is it recording?" preamble, the ten seconds of floor at the end. Trimming them off is the highest-value edit in existence, and it takes seconds: drop the MP4 below and drag the blue handles across the filmstrip to mark exactly what stays. The cut is frame-exact, the quality setting is yours (keep it original or squeeze it smaller), and nothing ever uploads — your footage never leaves the room it's in.
How to trim an MP4
- 1Drop your MP4 on the trimmer above. A filmstrip timeline appears with the full video pre-selected.
- 2Drag the blue handles to set start and end — drag the middle to slide the whole range, or click the strip to seek the preview.
- 3Hit Trim video and download. Pick Original quality to keep every pixel, or Balanced/Compact to shrink it on the way out.
Clean cuts, first try
Cut on motion, not mid-word
Ending a clip half a syllable in feels broken even when the picture is fine. Nudge the end handle to a breath or a beat.
Keep 0.5s of handle room
Tight trims feel abrupt in players with slow fade-ins. The tool enforces a half-second minimum selection for exactly this reason.
Trim before you compress
Cutting a 3-minute recording to its 20 best seconds shrinks the file far more than any quality slider — do the trim first, compress second.
Frequently asked questions
How do I trim an MP4 online free?
Drop it above, drag the handles to your start and end, hit Trim video. The clip renders locally and downloads as MP4 or WebM.
Will trimming lower my video quality?
Not if you pick Original quality — and even the Balanced preset is visually near-identical for most footage while cutting size.
Is there a file size limit?
Uploads over 1GB show a heads-up but still work; very long 4K files simply take longer to re-encode on slower machines.
Are my videos uploaded anywhere?
No. Cutting runs 100% in your browser via hardware acceleration — private footage stays private.
Can I trim WebM or MOV too?
Yes — WebM, MOV, MKV and more all load. Pick MP4 or WebM for the output.
