SignedDocs: find your format and open your signed documents

A free browser tool. Pick the format you received, or drop any file and let it work out the rest.

How it works

  1. Drop the file

    Choose it on your phone or computer. It is read in your browser and is not uploaded.

  2. See what is inside

    The document, the files in the package, or a clear message if it is only a signature or is encrypted.

  3. Save what you need

    Download the extracted document or a PDF copy, print it, and keep the original file as the record.

Where did your file come from?

Which page is for you?

Match the file you received, or where it came from. Each page explains the format and has the same field to open it.

Italy, Germany

.p7m

.p7m.xml.p7m.pdf.p7m

Suits 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.

Germany, Ukraine, Italy, Poland

.p7s

.p7s

Suits 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.

Italy

.tsd

.tsd.m7m

Suits 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.

Czechia

.zfo

.zfo

Suits 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.

Hungary

.es3

.es3.et3

Suits 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.

Poland

.xades

.xades.sig

Suits 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.

Spain

.xsig

.xsig.csig

Suits you if: you got a .xsig or .csig attachment from an administration or portal.

Extracts the readable document and shows the signer.

Ukraine, Slovakia, Estonia

.asice

.asice.bdoc.sce

Suits 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.

Lithuania

.adoc

.adoc

Suits 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.

What SignedDocs does and why

Opens the file without an upload

The file is read by your browser. No server receives its content, and there is no account to create.

Why: Signed files often carry contracts, invoices and official mail. They should stay on your device.

Shows who signed it

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.

Gets the document out

Download the PDF or other file from the container, download the original, or print the PDF.

Why: Most people cannot open .p7m and similar files without special software.

Reads e-invoices as invoices

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.

Unpacks containers with many files

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.

Matches a signature to its document

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.

Tells you when it cannot open a file

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.

About SignedDocs

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, nothing 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.

What is SignedDocs?

A free 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.

Which page should I pick?

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.

Is it safe?

Yes. The file is read in your browser and is not uploaded. There is no account. Keep the original file: it is the signed record.

Is it a legal validator?

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.
