Frequently Asked Questions
Can I draw my signature directly on the phone screen instead of taking a picture?
Yes. Most modern PDF reader apps, including WPS Office and Adobe Acrobat Reader, allow you to use your finger or a stylus to draw your signature directly on the touchscreen under the 'Create Signature' menu.
Why isn't my mobile signature syncing to my desktop application?
Syncing issues usually happen if you are logged into different accounts on your devices, or if one device lacks internet access. Verify that both your mobile phone and desktop are connected to the internet and logged into the same cloud account.
How do I remove or change a saved electronic signature on my mobile app?
To delete a saved signature, open the 'Fill & Sign' or 'Signature' tool in your PDF app, tap the signature icon, and then tap the minus (-) icon or swipe left on the existing signature to remove it. You can then select 'Create Signature' to add a new one.
Are electronic signatures added via mobile apps legally binding?
In many jurisdictions, standard electronic signatures are legally binding for most everyday personal and business documents. However, highly sensitive or regulated legal documents may require a cryptographically verified digital signature.
