How to sign a PDF on Android
Open your document, add a handwritten signature in the right place, then review, save, or share the signed PDF from your phone.
Sign a PDF without printing it
When a form or agreement arrives as a PDF, you can complete the signing step from your Android phone instead of printing, signing, and scanning it back. First check the document instructions and make sure you are signing the correct version.
If the document requires other details such as a name or date, add those before placing the signature.
How to sign your PDF
Open the PDF
Open PDF Fill & Sign and choose the document from your phone, recent files, or a supported share action. Check that every page is visible.
Complete any required details

Create or choose your signature
Open the signature tool and create a handwritten signature, or choose one you have already created in the app.
Place and adjust the signature
Move the signature to the line or box requested by the document. Adjust its size so it is legible and does not cover important text.
