Want to draw and write on PDF files?

This app will help you do just that! You can use your finger to write and draw different shapes, lines, and other graphic elements directly on PDF files, as well as use the eraser tool to erase anything you don’t like.

With the Draw on PDF – PDF Handwrite app, you can draw and write on PDFs directly through your device’s touchscreen, without the need for any additional hardware. You can also use the pen tool to create a new shape or draw a line, and use the eraser tool to erase any part of the drawing you don’t like.

This app also allows you to change the color and opacity of your pen and eraser tool, as well as the size of the eraser.
