FAQ
Questions, answered
How do I sign a PDF on my phone?
Open the PDF in the app, draw your signature with your finger, drag it into place and resize it, then save the signed copy and share it.
Can I add more than one signature?
Yes. You can add several signatures and place them on different pages of the same document.
Is the app free?
Every new account, including guest accounts, starts with welcome credits (50 at launch). Each tool use costs credits, usually 1. You can buy more credits inside the app in packs of 70, 150, 400 or 900.
Are my documents uploaded to a server?
No for the PDF tools: they run on your phone and your files stay on your device. The one exception is Doc to PDF (Word, Excel, PowerPoint, RTF, TXT), which uploads the file to our converter server over HTTPS. The upload and the result are deleted right after the conversion finishes.
Which phones does it work on?
InkSeal is a mobile app for iOS and Android.
Do I need to sign in?
No. You can use the app as a guest. Signing in with Google or Apple is needed to buy credits or use Doc to PDF, and any guest credits move into your account when you sign in.
Is a signature added with the app legally binding?
The app adds a drawn image of your signature to the PDF. Whether that is accepted depends on the document, the recipient and the laws where you are, so check with the requesting party if you are unsure. This is not legal advice.
