Updated 8 November 2026

## Steps

1. Open [the OkoSign checker](https://app.okosign.com/check). You need no account.
2. Choose your file. The checker reads .pdf, .asice and .edoc files.
3. Read the answer: who signed, when, and whether each signature is qualified.

## What the answers mean

The answer tells you three things. Whether each signature is qualified: made with a qualified certificate, with the same legal effect as a handwritten one. Whether the file was changed after signing, in which case it is not the one that was signed. And whether a signature was found at all: a file with none the checker can read says so.

## Nothing is kept

The file is checked and forgotten. The checker keeps no copy and needs no account.
