Do you need an app to sign a PDF on Android?
No. Chrome on Android (and Samsung Internet) is powerful enough to run Signvert entirely in the browser tab. There is no app to install, no account to create, and no file is ever uploaded to a server.
Step-by-step: sign a PDF on Android
- Open Chrome on your Android phone or tablet and go to signvert.com.
- Tap "Choose file" and select your PDF from Downloads, Google Drive, or your file manager.
- Draw your signature with your finger on the signature pad. Tap "Clear" to redo it if needed.
- Tap "Add to document", then drag the signature to the correct position on the page. Pinch to resize.
- Tap "Download signed PDF". The file saves to your Downloads folder.
Tips for signing on a small Android screen
- Rotate to landscape before drawing your signature — you get more horizontal space and a more natural result.
- Use a stylus if your phone supports one (e.g. Samsung S Pen) for a cleaner, more pen-like signature.
- Zoom in on the document before placing the signature so you can position it precisely.
- Save your signature after the first use — Signvert stores it locally so you can reuse it without redrawing.
What if my PDF is too large to open?
If the PDF is over 50 MB, compress it first using our File Resize & Compress tool, then open the compressed version for signing.
What if I need to sign a Word document?
Signvert also supports .docx files. Upload your Word document directly — it will be converted to a viewable format in the browser so you can place your signature, then download the signed PDF.
Is an electronic signature made on Android legally valid?
For most everyday documents — employment contracts, tenancy agreements, consent forms, HR paperwork — a drawn electronic signature is legally accepted in the UK, EU, US, and most other jurisdictions. For formal legal instruments (wills, property deeds), check with the receiving party about their specific requirements.
