Online Video Trimmer - Cut Video Online Free in Your Browser
VidShift is a free video file trimmer that runs entirely in your web browser. Drop in a clip, drag the timeline handles to mark the section you want to keep, and export a trimmed file in seconds. There is nothing to install, nothing to upload, and no watermark on the output - just a faster, more private way to cut video online.
What Is Video Trimming?
Video trimming is the process of cutting unwanted sections from the start, end, or middle of a video file to produce a shorter clip. Unlike full video editing, trimming keeps the rest of the footage exactly as it was recorded - the audio stays in sync, the resolution and frame rate are unchanged, and no transcoding is required for a basic cut. It is the fastest way to shorten a recording, isolate a specific moment, or prepare a clip for sharing without overhauling the file. A good online video trimmer should let you set precise start and end points, preview the result before exporting, and finish in seconds rather than minutes.
Supported Video Formats
VidShift's video file trimmer accepts every major container in use today. Drop in any of the following and start cutting right away:
- MP4 - the most common format for phones, cameras, and online video. Works with H.264, H.265 (HEVC), and AV1 codecs.
- WebM - the open web standard used by YouTube and many browsers, with VP8 and VP9 video.
- MKV - the Matroska container often used for high-quality recordings, screen captures, and downloads.
- MOV - QuickTime files recorded by iPhones, Macs, and many professional cameras.
- M4V, MPEG-TS, OGV - additional containers commonly produced by editors, broadcast tools, and older devices.
Fast mode exports an MP4 and uses stream copy where the source codecs allow, so processing is near-instant on most clips. Compatible mode re-encodes the video and lets you choose MP4, WebM, or MKV - useful when you need a frame-accurate cut or guaranteed playback on a specific device.
How Browser-Based Trimming Keeps Your Files Private
Most online video cutter tools require you to upload your file to a remote server, where it is processed, queued, and stored - sometimes for hours, sometimes indefinitely. VidShift takes a different approach: every byte of your video stays on your device. The trimmer runs as WebAssembly code inside your browser tab, using your own CPU to read, cut, and write the file. There is no upload progress bar because there is no upload.
This matters when you are trimming sensitive footage - medical recordings, confidential meetings, family videos, security camera clips, or unreleased work. Your file never touches a server you do not control, so there is no risk of it being indexed, leaked, or retained by a third party. The tool also works offline after your first visit, so you can trim videos on a plane, on a slow connection, or anywhere a normal cloud service would fail.
