Drag a crop box over your video, pick an aspect ratio, and export — everything happens in your browser.

MP4, WebM, or MOV — up to 500MB
The Video Cropper lets you trim the visible frame of any video with a draggable crop box, so you can cut out unwanted edges, straighten a composition, or reshape a clip for Instagram, TikTok, or YouTube Shorts. Everything runs locally in your browser using ffmpeg.wasm, so your video is never uploaded to a server.
Is this video cropper really free?
Yes. The Video Cropper is completely free to use, with no limits on the number of videos you can crop.
Do I need to install any software?
No. Everything runs directly in your web browser using WebAssembly — no downloads or plugins required.
Is my video uploaded to a server?
No. Your video is processed entirely on your device. It is never uploaded, stored, or seen by anyone else.
Why must crop dimensions be even numbers?
Most video codecs, including H.264, store color information at half resolution (a scheme called 4:2:0 chroma subsampling), which only works cleanly when both the width and height are even numbers. An odd dimension can make the encoder fail outright, so the tool automatically rounds your crop size down to the nearest even number before exporting.
What video formats are supported?
You can upload MP4, WebM, or MOV files up to 500MB. The cropped result is always exported as an MP4.
Does cropping re-encode and lose quality?
Yes — cropping changes the pixel dimensions of the video, so the video track has to be re-encoded (the audio track is copied untouched). The tool uses a high-quality encoding setting, so any quality loss is minimal and usually not noticeable.
All processing happens locally in your browser. Your video is never uploaded to any server.
