Why PDFs are password-protected
Organizations add passwords to limit casual access to contracts, payslips, or medical PDFs. Apps can set an open password (required to view) or permissions that restrict printing and editing. Legitimate reasons to remove protection include: you set the password and want a plain copy for archival; your employer gave you a known password and you need a workflow without prompts; or you are consolidating files you already have rights to modify.
How this tool unlocks (no cracking)
pdf-lib tries to load each PDF without a password first. If the file is encrypted, you must supply
the correct password — the same field is used for every file in your batch that needs it. The tool copies all pages
into a new document and saves it without encryption, named yourfile-unlocked.pdf.
If you forgot the password entirely, this page cannot help — we do not provide cracking. Request an unprotected copy from the sender or recreate from source files (Word, InDesign, scans). For privacy context on browser PDF tools, see how to compress a PDF (local vs upload sites).
After unlocking: merge, split, or compress
Once open, you can merge PDFs, split pages, or compress — all with the same local-processing model on DoItSwift.
