Crop the video formats you already use
Crop videos from phones, cameras, screen recorders, and editing apps. The tool accepts common containers and exports MP4, WebM, MOV, or MKV when you need a new format.
mp4
Best for compatibility
A practical default for sharing, uploading, and playback across phones, browsers, and social platforms.
mov
Apple and editing workflows
Useful when the cropped clip will return to QuickTime, Final Cut, or another Apple-focused workflow.
webm
Web and browser delivery
A modern browser-friendly choice, especially for web pages and smaller online video assets.
mkv
Flexible local archive
A flexible container for local storage when compatibility with a specific player is not the priority.
avi
Legacy camera and desktop files
Older AVI files may decode differently depending on the browser and the codecs inside the file.
m4v
MPEG-4 video from Apple devices
Common for videos exported by Apple apps and older mobile or media libraries.

Common video cropping scenarios
A tighter frame can make a video easier to watch, share, and reuse on different platforms.
Prepare social media clips
Crop landscape footage to square or vertical framing for feeds, stories, reels, and short-form video.
Focus a tutorial or recording
Remove empty borders and keep the screen, slide, or product area that matters to the viewer.
Clean up webcam recordings
Crop out unused desktop space or center the speaker before sharing a meeting or presentation recording.
Create product previews
Keep a consistent frame around a product demo, listing video, or customer testimonial.
Your videos stay on your device
The browser reads your file and passes it to a local Web Worker powered by MediaBunny. The source and cropped video are not uploaded to MediaKit servers. Remove the file or close the tab when you are done to release local memory.
FAQ
Frequently asked questions
Is my video uploaded?
No. Cropping runs in your browser with MediaBunny and Web Workers. The selected file is not sent to a MediaKit server.
Which video formats can I crop?
The input accepts common formats such as MP4, M4V, MOV, WebM, MKV, AVI, WMV, FLV, 3GP, MTS, TS, OGV, DIVX, and XVID. Actual playback depends on the codecs supported by your browser.
Can I crop to a specific aspect ratio?
Yes. Use a preset such as 1:1, 4:3, 16:9, 9:16, 3:2, or 21:9, or keep Free mode and set the crop area manually.
Does cropping reduce video quality?
Cropping requires a new video stream, so the result is re-encoded. Choose High or Very high quality when retaining detail matters, and preview the result before downloading.
How large can my video be?
Each input can be up to 2 GB. Large videos need enough available memory and may take longer on phones or older computers.
Can I crop a video on my phone?
Yes, use a current mobile browser and keep the page open while processing. Shorter clips use less memory and usually finish faster.
