An old contract from 2018 was encrypted with a password you never wrote down. The vendor has since gone out of business. You own the document and need to update one field. The file opens fine when you enter the password, but you can't remove restrictions or edit it without re-supplying credentials. PDFKits Unlock PDF removes password protection and edit restrictions from any PDF you have legal access to, free, in your browser.
The tool handles two scenarios: PDFs with permission restrictions only (you can open them but not edit/print/copy) and PDFs with both user password (opens) and owner password (restrictions). For permission-only restrictions, no password is needed — pdf-lib can write a new copy without the restriction flags. For full password protection, you need to enter the user password. PDFKits does not bypass legitimate encryption.
Drop the PDF into the tool. PDFKits inspects the encryption header and tells you what type of protection is in place — permission-only, user-password, or full encryption.
For permission-restricted PDFs, no password is needed. For password-protected PDFs, enter the user password you have legitimate access to. PDFKits validates it locally — if it's wrong, you'll see "incorrect password" with no info sent anywhere.
Click Unlock. PDFKits decrypts the file in your browser and writes a clean copy without restrictions. The unlocked PDF downloads directly. You can now edit, print, copy, and reuse it freely.
A small business owner encrypted invoices years ago with consistent passwords. Now they need to extract data for accounting software but can't copy text. Unlock to legitimate ownership restores full access.
You created a quote template five years ago, password-protected it before sending to clients, but lost the editable source. Unlock it to restore editing capability.
Archives often need PDFs in unrestricted form for long-term preservation. Removing access restrictions before storing in PDF/A archives ensures future readers can render the content.
Many "secured" PDFs disable accessibility extraction, blocking screen readers. Unlocking enables text-to-speech for visually impaired users on documents they legitimately own.
Online unlock services either upload your file (privacy risk) or charge per-document. PDFKits is fully browser-based and free. The tool only removes restrictions on PDFs where you provide the owner password or where the file uses permission-only restriction (no encryption). It does not bypass real encryption — that would be illegal in most jurisdictions and technically infeasible against AES-256.
No. PDFKits requires the legitimate user password for password-protected PDFs. For permission-only restrictions (no open password), no password is needed.
Yes, if you own the document or have explicit permission. Removing protection from copyrighted material you don't own is generally illegal under DMCA (US) and equivalent laws elsewhere.
No. The visible content is identical — only the encryption layer is removed.
Slightly smaller, since encryption headers and metadata are removed.
Yes — use our Protect PDF tool to apply new AES-256 encryption.
AES-256, AES-128, and legacy RC4 (40-bit and 128-bit). With the correct password, all are supported.
