Video Trimmer — Cut Video Online, Free & No Watermark
Trim and cut any video right in your browser. Set the start and end on a visual timeline and download the clip — no upload, no queue, no watermark and no sign-up. Your file never leaves your device.
Why use this online video trimmer
Nothing is uploaded
Your video is trimmed on your own device using WebAssembly. Files never travel to a server — nothing to store, scan or leak, ideal for private recordings.
No watermark, ever
The clip you download is your footage minus the parts you cut — no logo, overlay or watermark added. No premium tier to unlock a clean export.
Lossless & instant
Fast mode copies the stream without re-encoding, so the cut is quick and keeps the exact original quality. Need a frame-perfect cut? Switch to Precise mode.
How to trim a video online
- Drop your video into the box above or tap to browse. MP4, MOV, WebM, MKV, AVI and most other formats are accepted — no upload required.
- Pick start and end. Drag the two handles on the timeline, type exact times, or play the video and tap “Set start” / “Set end” at the playhead.
- Choose a mode. Keep Fast for an instant lossless cut, or pick Precise for a frame-accurate cut that re-encodes the selection.
- Press “Trim Video” and watch the progress bar. The first run downloads the engine once (~10 MB), then it is cached.
- Preview and download. Play the trimmed clip in the page, then save it — no watermark, no sign-up, ever.
Cut and trim video without uploading a thing
Video Trimmer is a free online tool that cuts and trims video right in your browser — no upload, no watermark, no sign-up, and your file never leaves your device. Drag two handles on the timeline to keep just the part you want, then download the clip in seconds. It is perfect for shortening a screen recording, clipping a highlight, removing dead air at the start or end, or cutting a long video down to the section you need.
Most online trimmers work the other way around: you upload your video to their server, wait in a queue, and then discover the free export carries a watermark or is capped at a few clips a day. Tools like Kapwing and VEED require an account and stamp a logo on free exports. This trimmer takes a different approach — it runs FFmpeg, the industry-standard media engine, compiled to WebAssembly directly inside your browser tab.
That design has three big benefits. First, privacy: your video is processed on your own machine and never travels to a server, so there is nothing for anyone to store or leak — ideal for confidential footage. Second, no limits and no watermark: because you use your own hardware, there are no upload caps, daily quotas, premium tiers or logos on the result. Third, speed and quality: the default fast mode copies the video and audio streams without re-encoding, so the cut is near-instant and the clip keeps the exact original quality.
Fast mode cuts at the nearest keyframe before your start point, which is how every lossless trimmer works, so the beginning can land a fraction of a second early. When you need a frame-accurate cut — for example to start exactly on a spoken word — switch to Precise mode, which re-encodes the selected range with H.264/AAC into a universally playable MP4. The first trim downloads the engine (~10 MB) once; after that it is cached and the tool works instantly, even offline. Everything is free, with no account, no watermark and no tracking of your files.
Frequently asked questions
How do I trim a video online for free?
Drop your video into the box above (or tap to browse), drag the start and end handles on the timeline to select the part you want to keep, then press “Trim Video”. The clip is cut in your browser and a download button appears in seconds. It is completely free with no watermark and no sign-up.
Is this video trimmer really without a watermark?
Yes. The trimmed video is identical to your source apart from the part you cut out — no watermark, no logo and no overlay is ever added. Unlike Kapwing or VEED, there is no paid tier required to remove a watermark, because none is added in the first place.
Is it safe to trim video online?
Yes. This trimmer runs FFmpeg compiled to WebAssembly inside your browser, so your video is never uploaded to any server. The file stays on your own device — you can even load the page, disconnect from the internet, and trimming still works.
Does trimming reduce the video quality?
In the default fast mode the video is copied without re-encoding, so the trimmed clip keeps the exact original quality with no loss. Fast mode cuts at the nearest keyframe, so the start can be off by a fraction of a second; if you need a frame-accurate cut, switch to Precise mode, which re-encodes the selected range.
What is the maximum video size I can trim?
There is no artificial limit. Because trimming happens on your device, the only ceiling is your browser's available memory — comfortably several gigabytes on a desktop. Fast lossless trimming is quick even for long, large videos because nothing is re-encoded.
What video formats can I trim?
You can trim MP4, MOV, WebM, MKV, AVI, M4V, 3GP, WMV, FLV, TS and most other common video formats. Fast mode keeps the original container; Precise mode outputs an MP4 (H.264/AAC) that plays everywhere.
