Lightweight ESRGAN rebuilds detail frame by frame on your GPU, with an automatic compatibility fallback. No account, credits, or surprise paywall at download.
Free export · No watermark · Audio preserved
The File API reads your video; decoding, AI inference, and encoding all happen on this device. The network is used only to download code and the model.
Export the finished MP4 without an account, credits, subscription, or download watermark.
Desktop accepts up to 720p with true 2× output: about 3s at 720p, 8s at 480p, or 15s at 360p. Mobile keeps a safer 360p resolution cap.
The browser checks duration, dimensions, and device support without uploading the file.
ESRGAN Slim uses WebGL to enlarge each frame 2×, with an automatic WASM fallback.
Frames are encoded and released every 0.5–2 seconds before the browser joins the MP4 segments and restores the source audio.
Yes. It primarily runs an ESRGAN Slim super-resolution model rather than stretching frames with CSS or bilinear interpolation.
Segmented processing lowers peak memory, but AI still computes every frame. The cap controls wait time, mobile heat, and background-tab suspension risk.
It is an experimental-release tradeoff for device coverage. It suits generated clips, memes, and slow footage better than fast-motion video.
No. Only the model and WebAssembly program are downloaded. The source, frames, and output remain on your device.
Yes, with a 10-second duration cap and a lower pixel budget. A current desktop Chrome or Edge browser is still more reliable.
