How to Unlock Multiple PDFs at Once

5 min read · September 2026

If you've ever received a batch of password-protected PDFs — salary slips, bank statements, ITR acknowledgements — you know how painful it is to open each one individually. Bulk Unlock solves this in one step.

When to use Bulk Unlock

Bulk Unlock is designed for when you have multiple PDFs that all share the same password. Common examples:

  • Monthly salary slips from payroll software (same password format every month)
  • Bank statements from the same bank account
  • Form 26AS or AIS downloads from the income tax portal
  • Tenancy or legal documents from the same firm

Step-by-step: Bulk unlock PDFs in your browser

1
Go to Bulk UnlockVisit pdfunlock.tech and click Bulk Unlock in the top navigation. No sign-up required.
2
Upload your PDF filesDrag and drop up to 50 PDF files at once, or click to browse. All files are processed locally in your browser — they never leave your device.
3
Enter the shared passwordType the password once. In Bulk Mode, the same password is tried on every file.
4
Click Unlock AllPDFUnlock processes all files simultaneously. You'll see a status for each file — unlocked, failed, or skipped.
5
Download your ZIPA ZIP file downloads automatically with all successfully unlocked PDFs inside, named exactly as the originals.

What if your PDFs have different passwords?

Bulk Mode requires a single shared password. If your PDFs have different passwords — like salary slips where each employee's PDF is locked with their date of birth — use Bucket Mode instead.

Bucket Mode tries a list of passwords against every file and automatically groups PDFs by which password opened them. The result is a ZIP with one folder per password — perfect for HR teams handling bulk payslip distribution.

Tip: Bulk vs BucketSame password for all → Bulk Unlock. Different passwords per file → Bucket Mode.

Is it safe to bulk unlock PDFs online?

With PDFUnlock, yes. The tool runs entirely in your browser using JavaScript — no file ever touches a server. Your PDFs are processed in memory and discarded the moment you close the tab. There's no account, no storage, and no log.

This matters especially for HR teams, chartered accountants, and legal professionals handling confidential client documents.
