About the free video trimmer
Trimming is the most common video edit in existence, and it should not require installing an editor or uploading gigabytes to someone else's server. This tool cuts your video directly on your device. In fast mode it does not even decode the footage: the compressed video stream is copied into a new file between your chosen points, which is why a multi-gigabyte recording trims in seconds, loses zero quality, and drains no battery. Because no server touches your file, there are no queues, no daily limits, and nothing for anyone to store.
The trade-off in fast mode is precision. Video streams can only be joined at keyframes, which typically occur every few seconds, so the cut snaps to the nearest keyframe before your chosen start and your clip may begin slightly early. For most jobs, trimming dead air off a recording or isolating a highlight, that is completely fine. When it is not, flip on the frame-exact switch: the tool re-encodes the video so the cut lands on your exact timestamps. Re-encoding takes longer and re-compresses the footage once, at high quality, but the cut is precise to the frame.
What people use it for
The classics: cutting the fumbling seconds off the start and end of a screen recording, pulling a highlight out of a long gameplay session, isolating one answer from an hour-long meeting recording, and shortening phone videos before sharing them. Creators slice long-form recordings into clips for Shorts and Reels, and AI video makers trim generated clips from tools like Sora, Veo, and Kling down to the seconds that actually worked. Since the fast mode is lossless, you can also use it to archive just the part of a recording worth keeping without degrading it.
Trim first, then compress or upscale
Trimming pairs naturally with the other video utilities. If your goal is a small file for chat or email, cut the video down here first and then run it through the free video compressor: every second you remove is bitrate the compressor can spend on the seconds you keep, so the same target size looks visibly better. Going the other way, if the clip you extracted is soft or low-resolution, the free AI video upscaler sharpens short clips, and Upsampler's premium Video Upscaler handles full-length videos at up to 4K output.
Formats, browsers, and limits
The trimmer accepts MP4, MOV, WebM, and MKV. MP4 and MOV come back as MP4, WebM and MKV come back as WebM, so compatibility never gets worse. Fast mode works in every modern browser because it never decodes the video. Frame-exact mode re-encodes, which requires WebCodecs, available in current versions of Chrome, Edge, Safari, and Firefox; the tool checks and tells you before starting rather than failing midway. File length is limited only by your device's memory, and files up to around 2 GB work reliably on typical hardware. No watermarks, ever.
