How it works
Three steps, zero uploads.
Drop in any MP4, MOV, WebM or MKV — even a 1GB screen recording or phone video.
Scrub the preview and press "Use current frame", or type the exact seconds.
Fast copy finishes in seconds; Precise re-encodes just your clip on your own hardware.
Trim large videos online — free, without uploading
Most online trimmers make you upload the whole file first — which for a 1GB screen recording means a very long wait just to throw most of it away. This tool reads the file directly on your device and streams it piece by piece, so trimming a huge video takes seconds, not minutes. There's no 200MB cap, no queue and no server involved: cut a large MP4, MOV, WebM or MKV to exactly the section you need and download it immediately.
Precise cut or instant lossless copy — your choice
Precise mode re-encodes the selected clip so the cut lands exactly on the frame you chose — ideal for social clips where timing matters. Fast copy mode doesn't re-encode at all: it copies the original video data untouched, finishing almost instantly with zero quality loss; the cut simply snaps to the nearest keyframe (usually within a second or two). Both happen entirely in your browser.
Trim MP4 without re-encoding — a true lossless cut
Most trimmers re-encode everything, which takes time and quietly reduces quality. Fast copy mode here does a genuine lossless cut: the original video data is copied untouched into a new file, so a cut on even a huge MP4, MOV or MKV finishes in seconds with zero generation loss. The only trade-off is that the cut snaps to the nearest keyframe (usually within a second). When the exact frame matters — a reaction, a goal, a punchline — switch to Precise mode and only your selected clip is re-encoded, at high quality, on your own hardware.
Cut long screen recordings down to the part that matters
A 40-minute screen recording where the bug appears for 20 seconds, a two-hour lecture where you need one explanation, gameplay footage with a single highlight — these are exactly what an in-browser trimmer is for. Because nothing uploads, a 1GB+ recording opens instantly: scrub the preview, press "use current frame" at the start and end, and download just that section. If the clip still needs to fit a chat-app limit afterwards, send it straight through the video compressor — under 16MB for WhatsApp or 10MB for Discord in one more step.
Frequently asked questions
Can I trim a video without losing quality?
Yes — Fast copy mode copies the original video data without re-encoding, so quality is mathematically identical to the source. The cut just snaps to the nearest keyframe.
How do I cut a section out of a long screen recording?
Drop the recording in (any size — nothing uploads), scrub the preview to the start of the part you want, press "Use current frame", do the same for the end, and download. For a 1GB recording this takes seconds in Fast copy mode.
Is my video uploaded to a server?
No. Trimming happens entirely inside your browser on your device's own hardware. You can watch the network tab: after the page loads, nothing is sent anywhere.
Can I trim a 1GB video?
Yes. The file is streamed piece by piece, so 500MB–1GB+ works on a modern desktop. Very large files on older phones may run out of memory — a desktop is recommended for 1GB+.
What's the difference between Precise and Fast copy?
Precise re-encodes so the cut is frame-accurate. Fast copy keeps the original data untouched (instant, zero quality loss) but may snap the start of the clip to the nearest keyframe.
Does it add a watermark or need an account?
Never. No watermark, no signup, no quota, nothing paywalled.
Which browsers work?
Chrome, Edge and Opera (desktop + Android) and Firefox 130+ are fully supported. Recent Safari versions work as well; older Safari may not support audio and the tool will tell you.
