Frequently Asked Questions

Will cropping reduce video quality?
Selecting "Original (No Re-encode)" uses stream copy, meaning the video and audio are extracted without re-encoding — zero quality loss. Other quality options re-encode the video for compatibility with certain aspect ratios.
Is my video uploaded to a server?
No. All cropping happens entirely in your browser using FFmpeg WebAssembly. Your file never leaves your device.
Can I crop to a specific aspect ratio?
Yes. Use the aspect ratio preset buttons — 16:9, 9:16, 1:1, 4:3, 4:5, 21:9 — to snap the crop region to a fixed ratio. You can also drag the handles freely for a custom ratio.
Can I enter exact pixel values for the crop?
Yes. The X, Y, Width and Height input fields accept exact pixel values. Changes are reflected on the canvas preview in real time.
Does it work on mobile?
Yes. The tool is fully responsive and touch-friendly. You can drag on mobile to set the crop region and use the number inputs for precise adjustments.

Free Online Video Cropper — Crop Any Video in Your Browser

Our online video cropper lets you remove unwanted edges, reframe the subject, or change the aspect ratio of any video file — all processed locally in your browser with FFmpeg WebAssembly. No uploads, no server, complete privacy.

Interactive Crop with Visual Preview

Rather than guessing pixel values, our tool shows a live preview of your video where you can drag directly on the frame to draw the crop area. Drag any of the four handles to adjust each edge independently, or lock to a preset aspect ratio.

Cropping Without Quality Loss

Selecting "Original (No Re-encode)" instructs FFmpeg to use stream copy mode, extracting the cropped region without transcoding the video data. The result is a cropped file with identical quality to the source within the selected area.
