Crop a video
Crop a video with a drag-and-drop box and presets for 1:1, 9:16, 16:9 and 4:5.

Cropping cuts away the parts of the frame you do not want: black bars baked into a screen recording, a messy edge, a person who walked into shot, or everything outside the vertical strip you need for Reels, TikTok and Shorts. Unlike resizing, cropping keeps the remaining pixels at full sharpness and changes what is in the picture rather than how big it is.
Drag the box over the video to position it, drag its handles to resize it, or type exact left, top, width and height values in the video's own pixels. Aspect presets lock the box to 1:1, 9:16, 16:9 or 4:5 while you move it; Free allows any shape. Scrub through the clip with the slider to check the subject stays inside the box for the whole video. With a preset you can also scale the crop to a standard size such as 1080 × 1920, which is what most platforms recommend. The keyboard works too: focus the box or a handle and use the arrow keys (Shift for bigger steps).
The crop is applied by FFmpeg in your browser and saved as an H.264 MP4 with AAC audio, or with no sound if you tick the option. Offsets and sizes are rounded to even numbers because the H.264 format requires it, so the box may shift by a pixel. The video engine (about 32 MB) downloads on first use; nothing is uploaded.
How to use it
- Drop a video and wait for the first frame to appear.
- Pick an aspect ratio (9:16 for vertical, 1:1 for square) or Free.
- Drag the box over the part to keep, resize it with the handles, and scrub through the video to check the framing.
- Choose the output size and quality, click Crop video, then download the MP4.
Frequently asked questions
Can I crop a video to 9:16 for TikTok or Reels?
Yes. Choose 9:16, move the box over the subject, and set the output to 1080 × 1920 to match what the apps recommend.
Is cropping the same as resizing?
No. Cropping removes part of the picture; resizing scales the whole picture. To change the resolution without cutting anything, use Resize video.
Does cropping reduce quality?
The kept area is not scaled unless you choose an output size, but the video is re-encoded to H.264, which is lossy. High quality keeps it visually identical at a larger file size.
The crop box does not appear. Why?
The browser has to be able to play the file to show it. Some codecs (for example HEVC on older Windows PCs or certain AVI files) cannot be previewed. Convert the video to MP4 with the video converter first, then crop.
Can I keep the original format?
The output is always MP4, the most compatible format. Use the video converter afterwards if you need MOV, WebM or another container.
