Frequently asked questions
Is the file uploaded to a server?
Yes, the file is uploaded temporarily to run this specific operation, then deleted automatically per our retention policy.
Does this affect file quality?
The tool aims for the best quality possible within the setting you choose.
Can enhancement add anything that isn't in the document?
No. Processing is pure signal processing with no generative AI: every output pixel derives from the surrounding input pixels; no letters, stamps or signatures are invented.
