Trim without uploads
Trim Video Without Uploading
Quick trims should be quick. Cut a 30-second clip from a 5-minute screen recording, trim the silent bit off the start of a tutorial, remove a stumble in the middle of a take. The trim itself is the work; everything else (upload, account creation, watermark removal) is friction that defeats the purpose.

The trim tool runs the same browser-local engine described on this page.
Why this matters
This page removes the friction by doing the trim locally. Drop, mark, cut, download. The whole workflow runs in your browser tab and a typical short trim takes under thirty seconds end to end.
For longer videos the time is dominated by re-encoding around the cut points, which is CPU-bound. There is still no upload step; just a wait while the encoder catches up.
What you actually get
Drop to download in under a minute
For short clips the entire workflow finishes before a cloud trimmer's upload progress bar would have moved meaningfully.
Multiple cuts in one pass
Jump cuts (remove segments) and inverse trims (keep only specified segments) both run in a single encoding pass.
No login or session state
Trim, download, close. The tool does not know who you are and does not need to.
Works on screen recordings, phone clips, drone footage
Any common video container that FFmpeg supports works as input. Output is standardised to MP4 with H.264.
How to trim a video without uploading
01 Open the Trim tool
Load the page below. WebAssembly caches in your browser.
02 Drop the file
Drag the video onto the upload area. The browser reads it locally.
03 Set cut points
Scrub the timeline and mark the sections to keep or remove.
04 Download the result
Run the trim. The new MP4 is saved to your downloads folder.
Frequently asked questions
How fast is a short trim?
For a 30 second clip out of a 5 minute source, expect under 15 seconds total from drop to download on a recent laptop. Most of that is the trim animation finishing; the encoding itself is a fraction of a second.
Why does my long trim take so long?
For longer videos, the encoder re-encodes the entire output to make the cuts frame-accurate. Re-encoding is CPU-bound and scales with output length. A 30 minute output takes a few minutes on a recent laptop.
Can I avoid re-encoding for speed?
There is a "stream copy" mode that cuts at keyframe boundaries without re-encoding. It is much faster but cut points snap to the nearest keyframe (usually every 1-2 seconds). For most trim workflows, frame accuracy is worth the encoding time.
Will the trim work on a MOV from my phone?
Yes. iPhone MOVs use H.264 or HEVC; both work as input. Output is always MP4 with H.264 for compatibility.
Is there any watermark on the trimmed output?
No. The trimmed MP4 contains only your video content. The free tier is the only tier; no paid version is gating watermark removal.
