What is WebSR?

Can I use it offline?
Yes, once the app is loaded, you can process images even without internet, depending on browser cache.
Why did my browser crash or show a "Size Exceeded" error?
Upscaling large images or long videos is memory-intensive. If your device or browser runs out of memory, processing may stop. Try using a smaller file, shorter video, or the Small network.
Why is the processing slow?
Everything happens locally on your device GPU. For the best speed, ensure "Hardware Acceleration" is enabled in your browser settings and use the smaller network when needed.
