About the Video Clipper
Drop in a video, drag the two handles on the thumbnail strip to mark your start and end points, and preview the selection right in the player before exporting. FFmpeg handles the actual cut inside your browser using WebAssembly, re-encoding the selected range and giving you a new file in MP4, WebM, or MOV. Your video never leaves your device — there's no upload step, no processing queue on someone else's server, and no size limit beyond what your own computer can handle.
How the trim works
The thumbnail strip is generated by sampling frames evenly across the full length of your video, giving you a visual map of the timeline instead of a blank bar. Dragging either handle updates the selected range live, and the time fields next to the timeline accept typed values in hours:minutes:seconds if you need frame-level precision that a mouse drag can't reliably hit. Pressing Preview plays back only the selected range so you can confirm the cut before committing to the export, which runs through a full re-encode rather than a fast stream copy — slower, but it guarantees the clip starts and ends exactly where you set the handles instead of snapping to the nearest keyframe.
Common uses
People reach for a clipper like this to pull a highlight out of a longer recording, trim the dead air off the front and back of a screen capture, cut a specific moment out of a downloaded video for sharing, or shorten a clip down to fit a platform's length limit before uploading. Because export includes a format choice, you can also use it as a lightweight way to hand off a MOV file as MP4, or the reverse, while trimming at the same time.
Choosing an output format
MP4 with H.264 video and AAC audio is the safest default — it plays on essentially every device and platform without conversion. WebM is a good pick if the clip is headed somewhere that favors open formats, like certain web embeds, and tends to produce smaller files at comparable quality. MOV suits workflows built around Apple's ecosystem or editing software that expects QuickTime containers as input.
Tips for a clean export
Zoom in on the timeline mentally by using the typed time fields for the final adjustment once you've got the handles roughly in place with the mouse — it's faster than nudging pixel by pixel on a short clip. If the export looks like it's stalled at 0%, give it a moment: encoding doesn't report progress until FFmpeg starts writing output frames, which can take a few seconds on longer files. Keep the browser tab open and in the foreground while exporting, since some browsers throttle background tabs in ways that slow down or pause WebAssembly workloads.
Processing happens on your device
The first time you export, your browser downloads a roughly 32 MB FFmpeg engine, cached afterward so later clips start faster. Everything past that download runs on your own CPU, which means export speed depends entirely on your hardware rather than a shared server's load. It also means the tool works offline once that engine is cached, and there's nothing stored about your video anywhere except in your browser's temporary memory for the duration of the job.
Working with longer source files
The thumbnail strip loads faster on shorter clips since it only has to sample and decode a fixed number of frames regardless of length, but on a long recording, generating those thumbnails can take a moment while the video's frames are decoded in the background. The timeline still works fine before thumbnails finish loading, so there's no need to wait for the strip to fill in before dragging the handles into rough position. Once you've narrowed the selection down with the mouse, switch to the typed time fields for exact placement.
Re-encoding versus a stream copy
Some video editors offer a faster "stream copy" trim that cuts without re-encoding, but it can only cut at existing keyframes, which means your start point often lands a second or two off from where you actually wanted it. This tool always re-encodes the selected range, trading some export time for a cut that lands exactly on the frame you chose. For short clips this difference in speed is barely noticeable; for longer selections, expect the export to take roughly as long as the source footage itself plays, depending on your device.

Frequently Asked Questions
Is the Video Clipper free?
Yes — completely free. No account, no subscription, and no file size limit.
Are my video files uploaded to a server?
No. FFmpeg runs locally in your browser via WebAssembly. Your video never leaves your device.
Do I need an account?
No account, no login, and no signup required.
How precise is the cut?
The clip is re-encoded with FFmpeg for frame-accurate cuts — you can set start and end points to within a fraction of a second. This takes longer than a stream copy but guarantees exact frame boundaries.
Why does export take a while?
Video re-encoding is CPU-intensive. WebAssembly runs single-threaded in most browsers, so speed depends on your processor. Short clips from a modern device typically finish in under a minute.
What output formats are available?
MP4, WebM, and MOV. MP4 is the most compatible choice for sharing and uploading to social platforms.
