Drop a video and scale it down to a smaller standard resolution like 1080p, 720p, or 480p. The aspect ratio is kept and the format stays the same. It all happens in your browser, so nothing is uploaded and there is no watermark.

Open the tool, drop in your video, then pick a smaller standard size like 1080p, 720p, or 480p, or set an exact width. The tool scales the video down to that size, keeps the aspect ratio, and re-encodes it. It all happens in your browser, so there is no upload step and no account to create.
Yes. The resizer is free to use, with no sign-up, no trial, and no watermark on the result.
No. The resize runs on your device with WebCodecs, so the video never leaves your browser and nothing is stored on a server. It works offline once the page has loaded.
Resize changes the resolution while keeping the same shape, so a 1080p clip becomes 720p at the same aspect ratio. Crop changes the shape by cutting away the edges, like turning a landscape clip vertical. Compress shrinks the file size at the same resolution. Use resize when you want a smaller resolution without changing the shape.
No. The resized video is saved in the same format you put in, so an MP4 stays an MP4. The video is re-encoded at the new size, so a single still paused and zoomed in can look a touch softer, but in motion it looks the same.
No. The presets scale the video down by the shorter side, so the aspect ratio stays the same and a 16:9 clip stays 16:9. If you want a different shape, such as square or vertical, use the Crop tool instead. Resize is for changing the resolution, not the shape.
No. This tool scales a video down to a smaller standard size; it does not enlarge a clip or add detail. The presets only list sizes below your source, and making a small video larger would just stretch the existing pixels and look soft. There is no AI here that invents detail, so for the sharpest result, start from the highest-resolution file you have.
Yes. The tool runs in your phone browser, so it works on iPhone and Android with no app to install. Pick your video, choose a size, and the result saves to your downloads or files.
There is no server limit, because nothing is uploaded. Very large videos are bounded only by your device memory, but the clips people usually resize are no trouble.
