About cropping video

Cropping changes the framing of a video — it throws away the edges of the picture and keeps the part you want. That is different from resizing, which keeps the whole frame and changes its dimensions. Cropping is what you want when a clip was shot wide but needs to be square for a feed, when the subject sits off to one side, or when the source has black bars baked into it.

How to crop a video

Cropping for social platforms

Black bars are part of the picture, not metadata. If a clip was letterboxed before you got it, every platform treats those bars as content — they eat into your frame and your file size. Cropping them out is the only way to get them back.

Frequently Asked Questions

How do I crop a video online?▼
Drop your video onto the page, drag the corners of the crop box to frame what you want, then click Crop & Export. The cropped video downloads to your device. Everything runs in your browser — nothing is uploaded.
Is my video uploaded to a server?▼
No. The crop is done on your own device with FFmpeg compiled to WebAssembly. Your video never leaves your computer.
How do I remove black bars from a video?▼
Click Remove black bars. The tool samples a frame, detects the letterbox or pillarbox edges and snaps the crop box to the real picture. You can still nudge it by hand afterwards.
Can I crop a video to 9:16 for TikTok or Reels?▼
Yes — pick the 9:16 preset and the crop box locks to that shape, so you can slide it over the part of the frame you want to keep. There are presets for 1:1, 4:5, 9:16 and 16:9.
Does cropping reduce the video quality?▼
Cropping requires re-encoding, so there is a small generational loss, the same as any editor. The output is H.264 MP4, which plays everywhere. Audio is copied across unchanged.
Is there a file size limit?▼
No fixed cap. Because the work happens on your device, the practical limit is your available memory rather than an upload quota.
