What you can do with Sign PDF
Signing adds your actual signature to a PDF — drawn, typed, or uploaded as an image — and places it exactly where the document needs to be signed, so you can return it without printing.
Sign a contract fast
Add your signature to an agreement and send it back the same day, with no scanner or printer needed.
Handle forms remotely
Sign school, medical, or HR forms from home and email the signed copy straight back.
Initial every page
Place your initials on each page of a multi-page contract where that is required.
Reuse a saved signature
Sign recurring paperwork with a consistent, professional-looking signature every time.
Sign PDF on Android without the Play Store
Play Store PDF apps tend to be ad-heavy, ask for broad storage permissions, and lock the actual sign feature behind a subscription. That is a lot to accept just to process one file, and it means giving an app ongoing access to your documents.
ContinuePDF runs in Chrome instead. There is no app to install and no special permission to grant — you simply pick your PDF from Downloads, Files by Google, or Google Drive, sign it, and the signed PDF saves back to Downloads where the Android share sheet can send it anywhere. Because the work is done on your device, your files are never uploaded.
Why choose ContinuePDF
No Play Store
Runs in Chrome — no app, no ads-heavy download, no broad permissions.
Drive & Files
Pull files from Downloads, Files by Google, or Google Drive.
Share sheet ready
Send signed PDF to any app via the Android share sheet.
Works on slow data
Processing is local, so it holds up on a weak connection.
Pro tip
Draw your signature slowly on a trackpad or touchscreen for a cleaner line, or upload a photo of your ink signature on white paper for the most authentic look. Size it to match the signature line rather than dropping it in oversized.
Frequently asked questions
Is a signature added this way legally valid?
In many places an electronic signature is acceptable for everyday agreements, but requirements vary by country and document type. For high-stakes legal documents, check what your jurisdiction or the other party requires.
Can I place the signature exactly where I want it?
Yes. You position and resize the signature freely, so you can drop it precisely on the signature line and add a date next to it if needed.
Is there a Sign PDF app for Android?
You don't need one. Sign PDF runs in Chrome on Android. Add your PDF from Downloads, Files by Google, or Google Drive, and signed PDF saves to your Downloads folder — no Play Store app required.
Where does the file go after processing on Android?
Signed PDF is saved to your device's Downloads folder. From there you can open it in any app or send it with the Android share sheet.
Is ContinuePDF free to use?
Yes. ContinuePDF and all of its tools, including Sign PDF, are free with no signup required. Because documents are processed in your browser rather than on our servers, we can offer the full feature set at no cost.
