Pick the format you received, or drop any file and let it work out the rest. A free account gets the preview and signer details; the full document is paid.
Create a free account with Google or your email, then choose the file on your phone or computer. It is read in your browser and is not uploaded.
The document, the files in the package, or a clear message if it is only a signature or is encrypted.
With your free account, preview the document and see who signed it. Downloading the extracted document or a PDF copy and printing are paid; keep the original file as the record.
Find the extension of the file you received. Each page explains the format and has the same field to open it.
.p7m.xml.p7m.pdf.p7mSuits you if: you got a PEC email, a supplier invoice or an official document as a .p7m file.
Reads the document inside, including a .pdf.p7m or .xml.p7m, and lists the signers.
.p7sSuits you if: you got a small signature file next to a document, or a smime.p7s file with an email.
Explains why there is no document in it, and checks a document you add against the signature.
.tsd.m7mSuits you if: you have a file wrapped in a timestamp (.tsd), or a mail message in .m7m.
Pulls out the file inside and shows the timestamp.
.zfoSuits you if: you downloaded a message from a Czech data box (datová schránka).
Lists the message documents, shows sender and date, and gives a ZIP of the files.
.es3.et3Suits you if: you got a Hungarian e-Szignó dossier as .es3 or .et3 from an official or business partner.
Opens the enclosed documents one by one and flags encrypted ones.
.xades.sigSuits you if: you got a signed XML file, as .xades or .sig, from a portal or partner.
Extracts the document from the XML and shows who signed.
.xsig.csigSuits you if: you got a .xsig or .csig attachment from an administration or portal.
Extracts the readable document and shows the signer.
.asice.bdoc.sceSuits you if: you have an .asice, .bdoc or .sce container that will not open on your device.
Unpacks the files in the container and shows the signatures.
.adocSuits you if: you received an .adoc package. This is a signed record, not an AsciiDoc text file.
Reads the main document and the attachments inside.
The file is read by your browser. No server receives its content; your account holds your email address, never your files.
Why: Signed files often carry contracts, invoices and official mail. They should stay on your device.
A signer panel lists the name, the issuer, the signing time, any timestamp and when the certificate runs out.
Why: It is the first question after you receive a signed file. The panel shows signature data, not a legal check.
Download the PDF or other file from the container, a PDF copy when it holds text, XML or an image, or print the PDF.
Why: Most people cannot open .p7m and similar files without special software.
A FatturaPA file is shown as a readable invoice with parties, lines, totals and payment details, plus a PDF copy.
Why: An invoice is sent as XML, which is hard to read. The XML stays the legal invoice.
A package such as .zfo, .es3, .asice or .adoc is listed file by file, with a ZIP download for all of them.
Why: One container often holds the main document and its attachments.
For a signature-only file such as .p7s, add the original and SignedDocs says whether it matches.
Why: A signature file on its own shows no document, which confuses people.
Encrypted files, unsupported formats and damaged files each get a plain message and a next step.
Why: An encrypted file needs the recipient's key. It is better to be told than to wonder.
SignedDocs exists because signed files are hard to open. Governments, tax offices and businesses send documents inside signature containers. Each country and each system has its own format. Every one needs different software, and people are left with a file they cannot read.
This site puts them in one place. Each format has its own guide for people who search for that exact file type. The viewer behind it is the same everywhere. Nothing is uploaded, no file is saved on a server, and the file stays on your device.
We keep a count of file types that people open, with the page, language and country, but never the file name or content. That tells us which formats to add next. The privacy page lists exactly what is recorded.
A tool that runs in your browser and opens signed or sealed files, such as .p7m, .p7s, .tsd, .zfo, .es3, .xades, .xsig, .asice and .adoc. It extracts the document inside and shows the signature data. A free account gets a preview and the signer details; the full document is paid.
Pick the format you received from the cards above. If you are unsure, use the viewer: drop the file and SignedDocs identifies it from its contents.
Yes. The file is read in your browser and is not uploaded. Your free account stores your email address, not your files. Keep the original file: it is the signed record.
No. SignedDocs shows the signature data it finds. For a legal check, use the official validator for your country, linked from the result panel. SignedDocs is not affiliated with any government body.
