ALTools
Crop Video
Drag handles to crop your video frame, just like cropping a photo. Private in-browser processing.
How to use this tool — step-by-step guideHow Video Cropping Works
Upload a video and drag the crop handles to frame the area you want—just like cropping a photo. ALTools crops on your device; nothing is uploaded and no account is needed.
Adjust the crop box with draggable corners, preview the result in real time, and export. Video is re-framed to the new dimensions while the original audio track is preserved unchanged.
Remove letterboxing, focus on a speaker, fit vertical social formats, or cut out distractions at the edges of screen recordings.
Cropping locally means previews update instantly and your source file never travels to a server. Undo and refine the frame until the composition looks right.
Save an MP4 at the cropped resolution—smaller file size when you cut away unused areas, with audio intact for sharing or further editing.

Trim Video removes time ranges. Crop Video removes pixels from the frame edges — like cropping a photo.
What happens to resolution and audio?
The export matches your crop box size. Audio is unchanged; only the picture is cropped.
Is my video uploaded?
No. Cropping runs entirely in your browser.
