How to sign a PDF on Android
Unlike iPhones, Android does not include a built-in PDF signing tool, so most people reach for an app from the Play Store. You do not need one. You can sign any PDF directly in Chrome on your Android phone, with your file staying on the device.

Step by step
- 01
Open the signer in Chrome
On your Android phone, open Chrome (or any browser) and go to the DocSignHub signer. There is no app to install from the Play Store and no account to create.
- 02
Upload the PDF
Tap the upload area and choose the PDF from Files by Google, Drive, Downloads, or an email attachment. It loads directly in the browser on your phone.
- 03
Draw your signature with your finger
Pick the draw option and sign with your fingertip or a stylus. You can also type your name in a handwriting font or upload a photo of your signature.
- 04
Place it and save
Drag the signature onto the line, pinch to resize, then download. Save the signed PDF to Files or share it straight from the Android share sheet.
Why skip a Play Store app?
Most free PDF signing apps on Android are ad-supported, request broad permissions, or upload your document to their servers to process it. For a one-minute task, that is a lot of trade-offs.
Signing in the browser avoids all of them: nothing is installed, no permissions are requested beyond picking a file, and the document is processed locally on your phone instead of being uploaded.
Signing a PDF from Gmail or Drive
If the PDF is a Gmail attachment, save it to Files or Drive first, or pick it directly in the upload dialog. From Google Drive, download it to the device and upload it in the signer.
After signing, use the Android share sheet to send the finished file back as a reply or upload it wherever it is requested — the whole round trip stays on your phone.
Works on any Android phone or tablet
Because it runs in the browser, the same signing flow works on any Android device — Samsung, Pixel, OnePlus, and the rest — and on Android tablets, where a stylus makes drawing a signature even cleaner. There is nothing device-specific to set up.
