Annotate PDF
Mark up a PDF with highlights, freehand drawing, arrows, lines, rectangles, ellipses and check marks. Your marks are drawn into the pages, so they look the same in every PDF viewer and when printed. The PDF is not uploaded.
Your files stay on your device. They are processed in your browser and not uploaded.
How to use it
- Drop a PDF on the box above, or choose it from your device.
- Pick Highlight, Draw, Arrow or another tool and mark up the page.
- Save the annotated PDF and download it.
Questions and answers
Do highlights follow the lines of text?
Not yet. A highlight is a see-through coloured box that you drag over the area you want to mark.
Can other people edit my annotations?
Your marks become part of the page, so they show in every viewer and printer. They are not separate comments that other apps can edit or hide.
Is my PDF uploaded?
No. The PDF is opened, edited and saved by your browser on your device. It is not uploaded to our server.
Does the PDF keep its bookmarks and links?
Yes. Your changes are added to a copy of the original PDF, so its pages, bookmarks, links and other form fields stay as they were.
Does it work offline?
Yes, after you have used it once: your browser keeps a copy of the tool, so it also works without an internet connection. Your files are never part of that copy.
