P7M
02 / Best for
- Read a signed contract or deed sent as document.pdf.p7m without installing a signature client.
- Recover the original PDF from files signed by a notary, a public administration or a certified provider.
- Open a signed attachment on a machine where no signature software can be installed.
03 / Why here
- The signed document is read out of the envelope byte for byte, so the extracted PDF is the exact file that was signed.
- Signed documents are often confidential: this runs entirely in your browser, so the file never reaches a server.
- Handles countersigned files that wrap one envelope inside another, and envelopes stored in base64.
04 / Keep in mind
- This extracts the document, it does not verify the signature: use a certified validation service if you need legal proof that the signature is valid and the certificate was not revoked.
- Detached signatures store the document separately from the .p7m, so there is nothing inside to extract.
- A P7M can wrap any file type, not only PDF. Signed e-invoices contain XML, and those are extracted as XML.

Questions, answered.
01What is a P7M file?
A .p7m file is a document wrapped in a PKCS#7 / CAdES cryptographic envelope, the standard format for digital signatures in Italy and the EU. The envelope holds three things: the original document, one or more signatures, and the signing certificates. That is why the name usually looks like contract.pdf.p7m, where the .pdf is the real document and the .p7m is the signature wrapper around it.
02Does a P7M file have a password?
No. A P7M is not password protected and there is no password to remove. It is a signature envelope, so the document inside can always be read by anyone who receives the file. The signature proves who signed it and that nothing changed afterwards, but it does not encrypt or lock the content.
03Does this tool check whether the signature is valid?
No, and that distinction matters. This tool unwraps the envelope and gives you the document. It does not verify the certificate chain, the revocation status or the timestamp. If you need to prove the signature is legally valid, use an accredited validation service.
04Are my signed documents uploaded anywhere?
No. The envelope is parsed by JavaScript running in your browser tab, and the extracted file is written straight to your disk. Signed documents are usually contracts and legal records, so this tool was built with no upload step at all.
05Is P7M to PDF free to use?
Yes, completely free, with no sign-up and no file-size limits. It runs entirely in your browser, so your documents never leave your device.
