Five questions to ask
- Where is the file processed? On your device or on a server? A trustworthy tool states it on the page.
- Does it ask for an account? Reading a file you already have should not require your e-mail address.
- What does the privacy page say? Look for cookies, analytics and retention periods. Vague text is an answer too.
- Who runs it? A named operator and a contact address should be easy to find.
- Does it claim too much? A browser tool that promises "legally valid verification" in one click is overstating what it does.
How ASiCE Viewer answers them
| Question | Answer |
|---|---|
| Where is the file processed? | In your browser. Nothing is uploaded |
| Account needed? | No |
| Cookies or analytics? | None |
| Who runs it? | Digixy, contact address on the About page |
| What does it claim? | Shows signer data and checks integrity; no legal verdict |
You do not have to take this on trust. The browser's network panel shows that the file is not sent anywhere, as described in open ASiC-E files online.
Warning signs
- The site shows a progress bar labelled "uploading".
- The result is a download link that expires, which means your file is on their server.
- You must disable an ad blocker or install a browser extension.
- The converted document has a watermark that disappears "in the premium plan".
Why a free viewer can exist
A local viewer is cheap to run: the visitor's own device does the work and the site only serves static files. ASiCE Viewer is run alongside an Android app. The app is free and financed by ads; the website has none.
Free and official
The most thoroughly checked free tool is the official DigiDoc4 client. It needs installation, and in return it validates signatures against trust lists. A light web viewer and the official client together cover nearly every need, and neither costs anything. The comparison is in free ASiC-E viewer.
Frequently asked questions
Can a free viewer steal my document?
A tool that uploads files could keep them. A tool that processes locally never receives them. Check which kind you are using.
Does ASiCE Viewer show ads?
The website shows no ads. The Android app does.
