AI Video Upscaler
Double the resolution of short clips with a real AI model running in your browser — waifu2x upscales each frame locally. No upload, no server.

MP4, WebM, MOV, MKV — anything your browser can decode.
PRIVATE BY DESIGN — PRIVATE BY DESIGN — decoding, processing and encoding all run in your browser's engine. No server sees your file.
How to Upscale a Video with AI
Drop a short clip (up to 6 seconds, up to 480×270), press Upscale 2x, and wait — each frame is enlarged by the AI model running in your browser. Processing is slow by design: it's real AI, not a fast blur.
Tip: best results come from clean, low-res sources — old 480p footage and screen recordings shine. Heavily compressed clips stay soft; AI can't restore what compression already destroyed.
FAQ
Frequently asked questions
Is AI Video Upscaler really free?
Yes — completely free, with no hidden fees, no premium tier and no signup required. The tool runs entirely in your browser.
Do I need to install anything to use AI Video Upscaler?
No. AI Video Upscaler works directly in your browser. There is no software to install, no app to download and no plugin required.
Is my video uploaded to a server when I use AI Video Upscaler?
Never. All processing happens locally on your device. Your file never leaves your computer, which is why there is no upload wait and no privacy risk.
Which video formats does AI Video Upscaler support?
It outputs H.264 MP4 at exactly 2x the input resolution, keeping the original audio. The AI model runs frame by frame in your browser.
What happens to my file after processing?
Nothing is stored anywhere. Once you close the tab, everything is gone. We have no server, no storage and no access to your files.
Will my video have a watermark?
No — every download is 100% watermark-free. EditVideo never adds logos, branding or watermarks to your files.
Why is AI upscaling slow?
Every frame goes through a neural network running on your device — that's real computation, not a stretch filter. A 6-second clip takes minutes. That's the honest price of doing AI locally with zero upload.
Why are clips limited to 6 seconds?
Frame-by-frame AI runs in your browser's memory — longer clips would exhaust it and fail at the last second. Split long videos with our video splitter and upscale the pieces.
Is this better than just resizing the video?
Yes — plain resizing stretches pixels into blur; the AI model redraws edges, textures and fine detail based on what it learned. On clean low-res footage the difference is clearly visible.
Does my video get uploaded anywhere?
No — never. Frames are extracted, upscaled by the AI model and re-encoded entirely on your device. The only download is the small AI model itself, cached by your browser.
