Sign PDF: Free, Quickly and Easily.
This app allows you to securely sign documents from any location using just your Android device.
It's user-friendly and offers unlimited free signing, making it the ideal choice for e-signatures on the go.

How to sign a PDF:
You can digitally sign a document in two simple steps, select your doc, add your signature, and send or share, that’s all, and yes, its free.


Our 'Sign PDF Documents' application offers an unbeatable solution for adding signatures to your PDFs, providing an optimal, free tool for quick and easy.

Prioritizing Privacy:
Signatures are generated directly on your device. Documents remain entirely within your phone, supporting offline functionality. We prioritize your privacy above all, steering clear of cloud storage or server use.

Rapid Signature Process:
Enjoy the simplicity of using our app with no need for registration, subscriptions, or payments.

User-Friendly and Swift:
Effortlessly insert electronic signatures into PDFs, Docs, and Images.

Sophisticated Signature Pad:
Our signature pad authentically replicates a pen signature, ensuring your digital e-signature doesn't appear as if it were created in a basic drawing program.

Selective Importing:
Import documents via Android's native picker without unnecessary access to all your files. Confidentiality is our cornerstone. You can even import files from Google Drive, Dropbox, and other sources.

e-Sign and Share:
With your edited file, opt to save the document as you wish or swiftly forward it through platforms like WhatsApp, Facebook, Email, etc.

New Feature - Password-Protected PDFs:
Now supports signing password-encrypted documents. The app will prompt for the password, decrypt the document for signing, and re-encrypt it post-signing, maintaining the document's original permissions.

Customizable Experience:
Choose your preferred ink color to match your favorite pen, offering options like classic blue, green, red, black, and more.

Beyond signing, this app doubles as a capable PDF Viewer & Editor.

Ratings and reviews

I think it is pretty standard you would almost certainly need to date your document, perhaps print your name and check boxes - the fact that this app doesn't do those things or even allow you to sign in landscape mode(would be so much easier!) makes it pretty much useless.. ended up having to get another app to do the job. I would give 0 stars because of how annoying the many pop up ads were.

Always has ads. Always takes long to load. Always have sign and export the document 5 times before it even works. It's annoying. The only thing I like about this app the fact that I can sign using my finger on my phone. One suggestion. Allow for a signature to be used more than once on a document that has more than one place for signing. Another suggestion. Fix the bugs.

After trying many top-rated apps after having lost my free to use Adobe sign app, I finally found an app that does not ask permission to ALL your files and/ or hundreds of euros per year subscription traps. It did what it needed to do, so I bought it at its fair price.
