Short answer: open the file in PDF Reader Lite, review the page and signature area, add your signature, confirm it is readable, then share the signed PDF. PDF Reader Lite is free forever.
Before you sign
Signing a PDF is usually a final step. Before adding a signature, check the basics so you do not send the wrong version.
- Confirm the file name and document type.
- Check the page number and signature area.
- Review names, dates, totals, and required fields.
- Make sure the document is the final version.
Steps to sign a PDF on Android
- Open the document. Start from recent files, favorites, or your Android file picker.
- Review the page. Use zoom and page controls to inspect the signature section.
- Add your signature. Use the signature or pen workflow and keep the mark inside the intended area.
- Check readability. The signature should be clear at normal zoom and should not cover required text.
- Share the signed PDF. Use Android sharing when the document is ready.
Common signing mistakes
| Mistake | Why it matters | Better approach |
|---|---|---|
| Signing before reading | You may miss changes, blanks, or wrong dates. | Scan the full page and key fields first. |
| Signature too large | It can cover important text. | Keep it inside the signature field. |
| Wrong file version | The recipient may reject the document. | Check file name and modified date before sending. |
| No final review | Small placement errors are easy to miss. | Zoom out and inspect the signed page. |
Important: Some legal, government, or business workflows may require a specific electronic signature system. PDF Reader Lite helps with everyday PDF review and signing workflows, but you should follow the rules required by the document recipient.
