Frequently asked questions
Is the AI image upscaler free?
Yes — it is completely free and runs in your browser, with no watermark.
How much can I enlarge an image?
You can upscale 2× or 4×. Very large images take longer and use more memory.
Does upscaling reduce quality?
No. Unlike simply resizing, the AI reconstructs detail and sharpens edges, so the result looks clearer rather than blurry.
What file types are supported?
JPG, PNG and WebP. You get a high-quality PNG back.
Are my images uploaded anywhere?
No. Everything is processed on your device — your images never leave your browser.
