Upscale your video to 1080p or 4K

Drop a clip to check its resolution and get the right upscale settings. Then upscale it with an AI video model, free and without signing up.

How it works, honestly: this page reads your video's details in your browser and tells you what scale factor you need. The actual AI upscaling runs on Upsampler's free video upscaler, where you upload the clip. We don't fake a preview or pretend to process anything here.

Three steps

  1. Check the source. Real resolution and bitrate matter more than the file name. A "1080p" download is often an upscaled 720p.
  2. Pick the target. 1080p for web and social; 4K for TVs, 4K timelines and YouTube's higher bitrate tier.
  3. Upscale with AI, then compress sensibly. Export at a bitrate that matches the new resolution (see the calculator).

FAQ

Is the video upscaling done on vidupscaler.com?

No. vidupscaler.com checks your video in your browser and recommends settings. The AI upscaling itself runs on Upsampler, where you upload the file.

Can AI really add detail to a low-resolution video?

AI video super-resolution models reconstruct edges and textures learned from training data. They do much better than simple resizing, but they cannot recover information that was never recorded, such as a licence plate that is only a few pixels wide.

What is the best resolution to upscale to?

Upscale to the resolution of the screen or timeline you deliver to. 1080p for most web and social use, 4K for 4K timelines, TVs and YouTube 4K.
