Need to open a .p7s file? Convert it to PDF in seconds, directly in your browser. No software installation required — works on any device.
A .p7s file is a digitally signed document using the PKCS#7 standard, which is the official digital signature format used by the Brazilian government (ICP-Brasil infrastructure).
In practice, a .p7s file is a "digital envelope" that wraps a PDF document with a cryptographic signature — guaranteeing that the document is authentic and has not been tampered with. To access the content, you need a tool that can "unwrap" the envelope and extract the original PDF.
P7S files are very common in Brazilian government systems, including NFe (electronic invoices), SEI platform, gov.br portal, Federal Revenue documents, and digitally signed contracts.
Think of it as a sealed certified envelope from the government. You need the right tool to open it and read the document inside.
The easiest way to convert a P7S file to PDF is using ExtratorP7S — a Brazilian online service specialized in ICP-Brasil documents:
Open in any browser on your phone or computer. No installation needed.
Drag and drop the file or click to select. Multiple files accepted at once.
Your PDF will be ready in seconds. Automatic download, no complications.
ExtratorP7S processes files directly in your browser. Your documents are never uploaded to external servers.
Windows, macOS, and mobile devices do not have native support for the PKCS#7 format. When you try to open a .p7s file, the system displays "Cannot open this file" because it doesn't know which program should handle it.
Many people try renaming the file from .p7s to .pdf, but this doesn't work — the internal format is still P7S and the file won't open correctly or may appear corrupted.
Changing the extension from .p7s to .pdf manually will not work and may damage the original file. Use a proper converter instead.
