Privacy: Unlike PASSFILE's regular browser tools, AI Upscale sends your image to Cloudflare for processing. PASSFILE does not intentionally store uploads or outputs. Do not upload sensitive documents or photographs in this beta. Learn more.

Rate limits: 3 requests per 10 minutes and 10 per day per IP. A global monthly safety quota also applies. Upscaling generates plausible details; it does not recover guaranteed authentic information.
How it works
After a low-friction Turnstile check, your photo is processed server-side using Cloudflare Images and ESRGAN. Results are returned as a download; the original is not intentionally stored by PASSFILE.
Not for evidentiary use. AI may invent image details. Don't use AI upscale for identity verification, legal evidence, medical imagery, or documents where exact content matters.
