Frequently asked questions
What do the tools cost?
Nothing. You need no account and no sign-up.
Are my files or entries uploaded?
For almost all tools, no: they run in your browser, nothing is sent to us or stored. Two exceptions need our server: the virus scan sends the file to the ClamAV scanner, the link check sends the link for a name lookup and the domain age. Even there neither the file nor the link is stored – each page says exactly what happens.
Do the tools work on a phone?
Yes, in any current browser. With very large images or files an older phone can get slow, because the work happens on the device itself.
Why does SafeDoc offer this?
Because we offer cloud storage, and these tasks come up all the time when working with files. If the tools help you, feel free to take a look at SafeDoc too – but you do not have to.
