Frequently Asked Questions about Annotate PDF
- What types of annotations can I add?
- The tool provides four main annotation types: highlights (color overlays on text areas), freehand pen drawings (free-form lines and sketches), text boxes (typed comments placed anywhere on the page), and shapes (rectangles, lines, and arrows). You can combine all four types within the same document and apply them across multiple pages.
- Are annotations permanent after I export the PDF?
- Yes. When you download the annotated PDF, all markup is flattened into the page content. The annotations become a permanent part of the document and cannot be removed or toggled off by the recipient. This ensures your highlights and comments are visible to anyone who opens the file in any PDF viewer. If you want to preserve an unannotated version, keep a copy of the original PDF before annotating.
- Can multiple people annotate the same PDF simultaneously?
- No. The 1984PDF annotation tool is designed for single-user workflows. You open a PDF, add your annotations, and export the result. It doesn't support real-time collaborative annotation or shared document sessions. For collaborative review, you would each annotate separately and then merge the feedback manually.
- Will the annotations show in all PDF viewers?
- Yes. Because annotations are permanently embedded (flattened) into the page content on export, they will appear correctly in any PDF viewer, Adobe Acrobat, browser-based viewers, mobile PDF apps, and print, without requiring any special plugin or annotation-aware reader. The markup is rendered as part of the page itself.
- Can I use the annotation tool on my phone or tablet?
- Yes. The tool runs in any modern mobile browser without an app download. Touch input works for freehand drawing and selecting annotation tools. The experience is most comfortable on a tablet with a stylus for detailed markup, but smartphones work for highlighting and text box annotations as well.
- Is the PDF annotation tool free?
- Yes, completely free. You can annotate and export as many PDFs as you need without any subscription, account requirement, or per-file charge. The downloaded PDF will not contain any watermarks, only your original content and the annotations you added.
- What happens to my PDF during the annotation session?
- Your PDF is rendered in the browser client-side during the annotation session, meaning page content is processed locally on your device. When you export, the file is handled to embed the annotations. 1984PDF does not store your document or retain copies of your annotated output after you download it.
