How to fill out a PDF on Android
Complete a PDF form from your phone by adding text, dates, and a signature, then choose the save option that works for you.
Fill a PDF without printing it
When a form arrives as a PDF, you do not need to move to a desktop or print the document just to enter a name, date, address, or short answer. PDF Fill & Sign brings the common form tools together in one Android workspace.
Before editing, keep an untouched copy of important paperwork. This makes it easy to start again if the document has strict formatting requirements.
How to fill out 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 before you begin.
-
Select the form tool
Open the form and signing tools, then select Add Text for names, addresses, dates, or other typed answers.
-
Add and position your text
Tap the place where the answer belongs, enter the text, and adjust its position so it stays inside the intended field or line.
-
Add dates, marks, or a signature
Use the appropriate tool when the form needs a date, tick, cross, or handwritten signature. Review the document's instructions before signing.
-
Review every page
Zoom in and confirm that each answer is readable, correctly placed, and not covering the original form text.
-
Save or share the completed PDF
Tap Save when the document is ready. The app will show the save options currently available to you. Choose one, create the finished copy, and share it with the recipient.
Tips for a clean, readable form
