Upscale Image — frequently asked questions

Is this AI upscaling?+

No. It's a high-quality bicubic resize with light sharpening — it enlarges cleanly but can't add detail that isn't there. True AI super-resolution needs a large model.

Best use?+

Making a small logo or graphic bigger, or bumping a photo up a size for print. A very low-res photo won't become sharp.

Do you upload my files to a server?+

No — every tool here processes your files entirely on your device, and nothing is uploaded to a server. The only exception is the AI tools, which send the extracted text (not the file) to Claude to do their work.

Is there a file size limit?+

There's no artificial limit we impose, but since processing happens in your browser, very large files (500+ MB or 1,000+ pages) are limited by your device's memory rather than by us.
