Questions & answers
How long does upscaling take?
Usually 10–60 seconds depending on the image size and your device. Large photos are reduced first so the AI can finish.
Is the AI model downloaded every time?
No. The small model is part of this site and the AI engine is cached by your browser after the first use.
Is AI Image Upscaler free?
Yes. Every tool on this site is free to use, with no signup, no watermark and no daily limit.
Are my files uploaded to a server?
No. Your files are processed inside your own browser on your device. They are never uploaded, so nobody else can see them.
Is there a file size limit?
There is no fixed limit. Because processing happens on your device, very large files depend on your phone or computer memory. Most files up to a few hundred MB work fine.
Does it work on mobile?
Yes. It works in Chrome, Safari, Edge and Firefox on Android, iPhone, Windows and Mac.
