How it works
Pages are compared by appearance using a perceptual fingerprint, so a page scanned twice is recognised even when the two scans are not byte-identical. This compares how pages look, not what they mean: two blank pages will always match, and two pages of the same form with different entries may match closely.

Questions
- Why do blank pages show as duplicates?
- They look identical, because they are. Run blank detection first if that is noise to you.
- Does it delete anything?
- No. It reports matches with a similarity score so you can decide.
- What similarity should I use?
- 98% catches genuine repeats. Lower it to find pages that are merely similar.
