Cleanor Labs
These sections explain the job in plain language and set expectations for what the tool should do well.
To resize a video, load one file, enter the target width and height, and choose how the frame should fit the new canvas. Contain mode scales the whole frame to fit inside the size you set (which can add padding), while cover mode fills the canvas completely by cropping the edges as needed. Then export to download a resized MP4.
Resizing changes the pixel dimensions of the video, which is what most upload limits, embed slots, and social formats actually care about. Because the resize and export run locally in your browser, the source file is never sent to a server, and the exported MP4 keeps its audio track.
Choose contain when you must keep every part of the frame visible, such as screen recordings or slides where cropping would hide content. Choose cover when filling the canvas matters more than showing the full frame, such as fitting a wide clip into a square or vertical social slot.
Most resize jobs are format chores for one specific channel or upload limit, so a direct resizer keeps the task simple instead of burying it inside a full editor. Common uses include shrinking a clip under a platform's size cap, matching a required resolution for a form or embed, and reframing a video for vertical, square, or widescreen layouts.
Short answers for the questions people usually have before trying a utility like this.

No. The resize and MP4 export run locally in your browser, so your video is never uploaded to a server.
Yes. The exported MP4 preserves the original audio track along with the resized video.
Yes. Use cover mode to fill the new canvas by cropping the edges; use contain mode to keep the full frame inside the canvas.
