Resize video dimensions
Click or drop a video file here
Video Resizer redraws your video at a new width and height on a canvas and records the result, entirely in your browser. The original audio is preserved by routing it through the Web Audio API alongside the resized video track, so the output isn't silent. Note: the output is always WebM, and dimensions aren't aspect-ratio-locked — entering a width/height that doesn't match your source video's proportions will stretch the result.
Does it preserve aspect ratio automatically?
No — enter a width and height that match your source video's proportions yourself, or the result will be stretched.
Does the resized video have audio?
Yes — the source video's original audio is captured alongside the resized picture and included in the output unchanged.
What output format do I get?
Always WebM.
Is my file uploaded anywhere?
No, resizing happens entirely in your browser.
