How this service works
Documents: DOCX template fill, Office to PDF, any file to Markdown, PDF to Word, OCR, PDF pipeline.
Output
Returns a JSON object containing the unlocked PDF either as inline base64 or a 24-hour download URL (with expiry, byte size, content type, and SHA256 hash). Also includes metadata such as operation type ('unlock'), input/output byte counts, page count, which password type was used to open the file, and flags like untrusted_content and active_content_removed.
Example use cases
Unlock contractor-sent protected invoice
“I received this PDF invoice but it's locked with the password 'Invoice2024'. Here it is as base64 — can you unlock it and give me back an accessible version?”
Strip owner restrictions from internal report
“This internal report PDF has an owner password that's preventing me from copying text or printing. The password is blank — can you remove those restrictions and give me a download link to the unlocked version?”
Open password-protected legal document from URL
“Can you unlock this PDF at https://files.lawfirm.com/contract_protected.pdf? The user password is 'Contract#99'. Give me back the file as base64 so I can process it further.”
Technical details
Endpoint
POSThttps://docs.tanod.dev/v1/pdf/unlock?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to programmatically remove password protection or owner restrictions from a PDF, especially in an automated pipeline where you have the password at hand. It supports both URL-based and base64 inline input, making it flexible for agent workflows. Prefer it over general PDF tools when you specifically need decryption/unlocking as a discrete step, and the output format flexibility (base64 vs download URL) lets you keep large files out of context windows.
Side effects
- Wrong or missing password returns an authentication error
- PDF URL exceeds 20 MB or base64 payload exceeds 10 MB decoded triggers a size rejection
- Private, internal, or IP-literal host URLs are refused
- Malformed base64 input causes a decoding error
- File is not a valid PDF returns a format error
- Neither url nor pdf_base64 provided results in a validation error
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| url | — | Public http(s) URL of the PDF (at most 20 MB; private, internal and IP-literal hosts are refused); or use pdf_base64. |
| output | string | base64 (default): the file comes back inline as base64. url: the file is stored for 24 hours and the reply carries a download link (url, expires_at, bytes, content_type, sha256) instead of the base64, which keeps the file out of your context window. |
| password | string | User or owner password; "" opens owner-password-only PDFs; never logged. |
| pdf_base64 | — | The PDF as base64 (at most 10 MB decoded per request); or use url. |
