Frequently Asked Questions

Everything you need to know before you get started.

What markup tools are available?

Tool list

DraftPDF includes: highlight, underline, strikethrough, freehand pen, shapes (rectangle, ellipse, polygon, line, arrow), sticky notes, callouts, and stamps.

Can I change the colour of markups?

Colour customisation

Yes. Every annotation type has a colour picker. You can set custom colours for fills, strokes, and text, and the editor remembers your last-used colours.

Can multiple reviewers mark up the same PDF?

Collaboration

Each reviewer can open the PDF in their own DraftPDF session and add their markups, then save. The resulting PDFs can be compared or the annotation layers can be merged into a single document.

Will markups appear when I print?

Print & export

Yes. When you save and download the marked-up PDF, all annotations are embedded in the file and will print or display in any standard PDF viewer.
