Lift text
Remove hidden info
Black out names · numbers
Covered pages are turned into images, so their whole text layer is gone. Safest, but those pages can't be searched or copied and the file gets bigger.
PDF only — no HEIC photos or video. Text is lifted from the first 20 pages, black-out works up to 60 pages, and locked (encrypted) PDFs can't be opened. The blacked-out copy is a newly built PDF, so bookmarks, attachments, form fields and JavaScript are left out, and comments on covered pages too. Removing hidden info leaves the text and images on the pages alone.
The engines (pdf.js, pdf-lib and the reading engine) load from this site, and your file and results are not stored anywhere.
