Using a dedicated PDF editor app: Many PDF editor apps available on the Google Play Store offer digital signature functionality. These apps often allow you to create a signature using your finger or a stylus, save it, and then apply it to your PDFs. Popular options include Adobe Acrobat Reader, Foxit PDF Reader, and WPS Office. These typically allow you to add visual signatures and may incorporate more advanced features like timestamping or signing using certificates for stronger digital authentication. Each app has a slightly different workflow for signature creation and application.
Utilizing built-in Android features (limited): Some Android devices may offer basic PDF annotation tools. While not all devices support digital signatures directly, some provide the ability to add handwritten signatures using a stylus or finger. These are usually only visual signatures, lacking the security of cryptographic signatures.
Employing cloud-based services: Services like DocuSign or Adobe Sign offer digital signature capabilities that are accessible through their Android apps. These are particularly useful for documents that require legally binding signatures from multiple parties. However, this typically requires an account and subscription.
To use any of these methods, typically you will open your PDF in the chosen app, locate a "Signature" or "Sign" tool, create your signature (either by writing it, importing an image, or selecting a preset), then place the signature on the designated area of your document. Finally, save the signed PDF.
Simple Answer:
Many Android apps let you digitally sign PDFs. Popular options include Adobe Acrobat Reader and Foxit PDF Reader. Usually, these apps have a "Sign" button where you can create and add a signature to your PDF.
