About the Video Cropper

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.

Features:

  • Draggable crop box with 8 resize handles
  • Aspect ratio presets: Free, 1:1, 4:5, 16:9, 9:16
  • Exact pixel input for precise crops
  • Privacy-first

How to Crop a Video

  1. Upload a video by dragging it in or clicking to browse
  2. Choose an aspect ratio preset or drag the crop box freely
  3. Fine-tune the position and size with the pixel inputs if needed
  4. Click "Crop Video" and download the result

Frequently Asked Questions

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.
