Frequently Asked Questions
Everything you need to know before you get started.
What can I edit in a PDF?
Supported edits
DraftPDF supports adding and editing annotations: free text, shapes, stamps, highlights, underlines, and strikethroughs. It focuses on annotation-layer editing rather than modifying original body text. Measurement tools and callouts are coming soon.
Does it work on all browsers?
Browser compatibility
DraftPDF works on any modern browser that supports WebAssembly — Chrome, Edge, Firefox, and Safari are all supported. No browser extensions are required.
Does it work offline?
Offline support
Yes. Once the editor has loaded, it works entirely offline. Your documents are never transmitted anywhere, making it safe to use on confidential files.
How do I save my edits?
Saving & exporting
Click the save/download button in the top menu. DraftPDF flattens your annotations into the PDF and downloads the result to your device. Edits remain on the annotation layer so you can continue editing later.
