How to crop a video
2
Set ratio and framing
Choose a preset. Drag the picture into position, then adjust the zoom slider from 1 to 3.
3
Watch the crop preview
The preview loops without sound. Check movement across the clip; it is not the encoded output.
4
Export and inspect the MP4
Keep the tab open while export runs and downloads the file. Open that MP4 to check framing and audio. Export again after adjustments.
Reframe one clip with a fixed crop
Four aspect ratios
Choose 16:9, 9:16, 1:1 or 4:3. There is no arbitrary ratio or pixel-dimension entry.
Keep the useful area
Move the picture inside the frame and use 1–3× zoom to exclude unwanted edges or empty space.
Local processing
The video stays on your device. The browser downloads the processor before export.
Free, with originals intact
No account or credits. The cropped download is separate from the source file.
MP4 download
Successful exports save as cropped-video.mp4. There is no output-format or resolution selector.
Review moving footage
One crop applies throughout the clip. Check that important action stays inside it before exporting.
Video inputs and output
Try compatible MP4, MOV or WebM. Both preview playback and export must support the source. File extensions alone do not guarantee success.

Example: a square product demonstration
Choose 1:1 for a product on a wide tabletop. Position the product centrally and use only enough zoom to remove empty edges. Watch the presenter’s hands: if they leave the square, reduce zoom or use a wider ratio. Check the downloaded MP4 before sharing.
For duration changes, use Trim Video. To keep the whole frame, use Social Media Resizer. For selected-person tracking, see Auto Reframe. Browse all free tools.
Video cropping questions
Is the video cropper free?
Yes. No account, credits or added DojoClip watermark.
Is my video sent to a server?
No. The media is processed locally. Internet is needed to load the processor; keep the downloaded result before leaving.
Can I draw a freeform crop or enter exact coordinates?
No. Use the four ratios with drag and zoom. There are no freeform handles or coordinate fields. Export aligns the crop to even pixels, so edges may shift slightly.
Does zooming preserve all the original detail?
Zoom selects a smaller area; it does not recover detail or upscale the crop to a chosen resolution. Export re-encodes the video, so quality and size can change. Lossless output is not guaranteed.
Why might a file fail to crop?
The browser preview or processor may not support its codecs. There is no fixed input size or duration cap, but large files can exceed available memory. Try a smaller compatible MP4 if needed.
Why is the preview silent?
Preview audio is muted for framing. Export attempts to copy the source audio without re-encoding; incompatible audio can prevent MP4 export. Listen to the download. No mute or audio-replacement control is provided here.
Will the crop follow a moving person?
No. The rectangle stays fixed for the whole clip. There is no tracking, animated crop, blur mask or background removal.
Does cropping remove seconds from the video?
No. It removes picture edges, not a time range. The whole clip is processed; shortening and keeping the full picture in a new layout are separate tasks.
