For YouTubers framing footage for standard widescreen uploads or vertical Shorts.
YouTube spans two shapes: standard uploads are widescreen 16:9, while Shorts are vertical 9:16. Getting the framing right means your video fills the player instead of showing bars. This tool reframes your footage to the ratio you need in your browser, with a zoom control to keep the important action in frame when converting between shapes. It runs locally, so your video isn't uploaded, and the export has no watermark and needs no account — so your content looks clean and native. Use it to standardize a clip for a regular upload or carve a vertical Short out of landscape footage. Drop in the video, choose your ratio, frame it, and download. It's the free, private way to prep video for YouTube without a desktop editor or a watermarking service, and it works on whatever device you recorded on.
