Frequently asked questions
Does changing DPI change quality?
No. In Only change DPI mode the pixels stay the same. Only the DPI value stored in the file changes, which is what portals check.
Is DocsGinie free?
Yes. Every tool is free. Tasks up to 25 pages need no account; for bigger tasks just sign in with Google, still free.
Is it safe for Aadhaar, PAN or bank documents?
Your files are processed only inside your browser and are never uploaded to our servers. Still, only share such documents with organisations that genuinely need them.
