How to sign a document on an Android phone
The usual Android route to signing something is a Play Store search, three apps that all want an account, and a watermark on the file at the end. None of that is necessary. Chrome on Android can open the document, take the signature and hand back a finished file, and because nothing is installed, nothing gets storage access, contacts access or a notification habit.
Drop your document here and sign it now. PDF, Word and Excel all work: a .docx or .xlsx is laid out in your browser exactly as it was written, so there is nothing to convert first. Add a signature, a date, a company stamp or a watermark, then download it sealed. Free to start, no account, and the file is never uploaded to open it.
How to sign a document on an Android phone, step by step
- Open the file in Chrome, From Gmail, Drive, Downloads or a link. PDF, Word and Excel all open, and a .docx keeps its layout.
- Zoom in, then sign, Pinch until the signature line fills the screen. This is the whole difference between a signature and a scribble on a phone.
- Add the date and a stamp if needed, The date fills itself in, and a company stamp can go on beside the signature in the same pass.
- Save it back to the phone or to Drive, Downloads, Drive, or straight into the reply you are sending. On a managed device where local downloads are blocked, Drive is the way out.

Frequently asked questions
How do I sign a document on my Android phone for free?
Open it in Chrome, sign it, and save it back. Designing and signing is free, and you pay $1.50 only when you download a finished document, or nothing at all on a paid plan.
Can I sign documents on mobile without an app?
Yes, and it is worth avoiding one. Signing is something most people do a few times a month, which does not justify an app with storage permissions and an account attached to it.
Will the signed file have a watermark on it?
No. Free Android signing apps commonly stamp their own name across the page, which is exactly the thing you cannot send to a client. Nothing is added here beyond what you place.
Can I sign a Word document on Android?
Yes. Drop the .docx in and it is laid out as written, then sign it and download either a PDF or the Word file back.
What if my phone will not let me download the signed file?
Managed devices often block writes to local storage. Save to Google Drive instead, which is allowed on most such setups.
What PDF Verified is, and what it is not
PDF Verified is a tool for preparing, signing, stamping and checking documents. It is not a law firm, a compliance service or a forensic examiner, and nothing here is legal, financial or compliance advice. Requirements differ by country, by document type and by the party asking, so check what applies to your document before you rely on it, and take advice where the document matters. You are responsible for the documents you create, sign and send, and for having the authority to do so: signing or stamping in somebody else name, or as an organisation you do not represent, is forgery whatever tool is used. To the extent the law allows, we accept no liability for how a document made with this tool is used or relied on. The full position is in our terms of service.
