About this tool
No accounts, no uploads, no watermarks — just the operation you came for. Check whether a PDF is encrypted or password-protected, and see its page count and version. No password needed. Processing runs locally in your browser's memory — the document is never transmitted, and closing the tab clears it completely. The workflow is deliberately short: load the file, choose the options on the page, run the operation, and save the result. Every choice is applied before the file is written, so re-running with different settings takes seconds. Practical limits apply (see the on-page limits), and it pairs well with the related tools linked beside this page when one step is not the whole job. Key facts — Processing: runs entirely in your browser, client-side; Access: free with no account required; File limits: see the on-page limits; Privacy: the file never leaves the device.

FAQ
Will my file be uploaded?
No. Everything runs locally in your browser — your file is never uploaded and is cleared upon closing the page.
Are there any limits?
Only checks encryption status and basic metadata without attempting password decryption.
Is the security strong enough?
Inspection is performed entirely locally in your browser; it only detects whether the file is encrypted, does not attempt cracking, and never reads or asks for passwords.
Can I process multiple files in bulk?
A single tool page handles one task at a time; for bulk work use the Batch Processing workflow and add this tool as a step to run a whole set at once.
Is the processed file still editable?
This tool only displays the inspection status on the page without generating an output file; your original document remains unchanged.
