Frequently Asked Questions

How does the image upscaler work?

Our upscaler uses advanced bicubic interpolation with progressive passes and unsharp masking, all processed in your browser using the Canvas API. No data is sent to any server.

What image formats are supported?

JPG, PNG, and WebP images are supported. The output is always a high-quality PNG file.

Is there a file size limit?

There is no hard limit, but very large images (over 4000px) may be slow on mobile devices. We recommend using 2× for large images.

Is my image data safe?

Yes! Everything is processed 100% in your browser. Your image never leaves your device — no uploads, no storage, no tracking.
