Android phones have no built-in PDF signing tool. iPhones have iOS Markup. Android does not have an equivalent. The fastest free solution is to open PDFWix in Chrome — draw your signature with your finger or type it, place it on the page, and download the signed PDF. No app to install from Google Play, no account, no DocuSign or Adobe Sign subscription. Works on any Android phone — Samsung, Pixel, OnePlus, Xiaomi.
Sign a PDF on Android free in Chrome — draw, type or upload your signature and place it anywhere. No app install, no Adobe, no account. Works on any phone.
Most modern Android phones and tablets (Samsung Galaxy Tab, Pixel Tablet) work with capacitive styluses for signature drawing. Samsung's S Pen produces especially clean signatures because it samples pressure and tilt. If you don't have a stylus, switch the signature mode from Draw to Type and pick a handwriting-style font — the result is consistent across signings and looks professional on the resulting PDF. Either way, PDFWix flattens the signature into the page on download so the recipient sees it identically in any PDF viewer, including Adobe Acrobat, Microsoft Edge, Apple Preview and Google Drive.
No. Unlike iPhones which have iOS Markup built in, Android has no native PDF signing tool. The closest built-in option is Google Drive, but its full eSignature feature requires a Google Workspace paid account. For free signing without any account, use PDFWix in Chrome.
Yes. Open pdfwix.com/sign-pdf in Chrome on your Android phone. Upload your PDF, draw or type your signature, place it on the page, and download. No app to install from Google Play, no account required.
Open the PDF in Google Drive, tap the three-dot menu, select Open with Google Docs, tap Insert → Signature, draw with your finger, then export as PDF. Note: the full Google Drive eSignature feature requires a Google Workspace (paid) account. Personal Gmail accounts have limited access.
