FAQ
Does this apply any effect or filter?
No. It just makes the image bigger — the same way Photoshop's Image Size dialog does. No AI, no filter, no "enhancement". The original look is preserved.
Will my image leave my device?
No. Everything runs in your browser. Open DevTools → Network while you upscale and you will see zero outbound file uploads.
Why is the output capped at 6000×6000?
Browser canvases use about 4 bytes per pixel of RAM. Above 6000×6000, mobile browsers (especially iOS Safari) crash the tab. The cap is a safety limit.
Can it add detail that wasn't in the source?
No. AI upscalers can invent detail; this tool only enlarges what is already there. So a small image stays a small image — just with more pixels.
