Add lined, dotted, or graph-paper backgrounds to a PDF
Choose a background that supports the page rather than distracting from it. You can use different styles for different pages and keep the original PDF as a separate copy.
How it works
Open an existing PDF or start with blank pages.
Choose a background and apply it to the pages you need.
Preview the result, then export the finished copy.
Questions people ask
Will a theme cover my existing writing?
Themes are intended as backgrounds. Preview the page before export, especially when the original already has pale text or fine diagrams.
Can I use more than one theme in the same PDF?
Yes. For example, add graph pages for calculations and lined pages for written summaries.
Will it look sharp when printed?
The backgrounds are drawn as PDF shapes rather than one large background image, so lines and dots remain clean at normal print sizes.
Does my PDF get uploaded?
No. The tool reads and edits the file in your browser. Exported files are downloaded directly to your device.
Should I keep the original file?
Yes. Exported files are new copies, but keeping the original lets you revisit a different edit or recover from a mistake.
