The Best App for Signing Documents

Our ‘PDF Document Signer’ is the perfect solution for quickly and effortlessly adding signatures to your files.

Your Privacy Comes First

Signatures are created directly on your device, and your documents never leave your phone. We don’t use cloud storage or external servers, so you can sign even without an internet connection.

Sign in Seconds

No registration, no subscriptions, no payments required—just sign and go.

Simple and Intuitive

Easily add your electronic signature to PDF files, text documents, and images without hassle.

Realistic Signature Appearance

We’ve designed the app to make your signature look as natural as possible—just like signing with a pen, not a basic digital scribble.

No Unnecessary Permissions

Open PDFs from your Android file manager without granting full access to your data. You can also import files from Google Drive, Dropbox, and other platforms.

Sign and Share

Once signed, save the document to your phone or instantly share it via WhatsApp, email, Facebook, and more.

Supports Password-Protected PDFs

You can even sign encrypted documents. Simply enter the password, the app will decrypt the file for signing, and then re-encrypt it to keep it secure.

Customize Your Signature

Choose your preferred ink color to make your signature look just the way you want. Options include classic blue, black, red, green, and more.

More Than Just Signing

Beyond signing, the app also works as a PDF reader and editor, making document management easier than ever.
