  2. Select a page from the thumbnail gallery on the left to open it in the interactive editing canvas.
  3. Use the toolbar to choose your editing tool: Text (add typed content), Pen (freehand drawing), Highlight, Sticky Note, Whiteout, or Shapes.

Is the PDF editor free on PDFA2Z?
Yes, completely free. No signup, no watermarks, unlimited use.
Does the PDF editor work on mobile?
Yes. The editor is touch-optimized and works on iPhone, iPad, and Android devices. Freehand drawing is especially natural with a touchscreen.
Can I delete or replace existing text in a PDF?
Directly editing existing PDF text is complex in a browser-based tool. However, you can use the Whiteout tool to cover existing text and then add new text on top of it.
Can I add images to a PDF?
Yes. Use the Image Insert tool to upload and place images anywhere on any PDF page. Resize and reposition by dragging.
Can I highlight text in a PDF?
Yes. The Highlight tool lets you drag-select areas to apply yellow, green, or pink highlight overlays over any part of the document.
Can I add sticky notes or comments?
Yes. Sticky notes can be placed on any page to add reviewer comments that appear as pop-up annotations in standard PDF readers.
Can I whiteout (cover) existing text?
Yes. The Whiteout tool draws a white rectangle over any area, effectively hiding the content underneath. Use our Redact PDF tool for permanent data removal from the PDF stream.
What drawing tools are available?
Freehand pen, straight line, rectangle, circle, and arrow tools are all available in the toolbar.
Are my edits saved permanently in the downloaded PDF?
Yes. When you download the edited PDF, all annotations, text, drawings, and signatures are permanently embedded. Recipients do not need special software to see the edits.
Can I undo edits I don\
Yes. Use Ctrl+Z (or Cmd+Z on Mac) to undo your last action. You can undo multiple steps.
Can I edit password-protected PDFs?
Only if you know the password. Unlock the PDF first using our free Unlock PDF tool, then edit it in the editor.
Is there a page limit for the PDF I can edit?
No hard limit, though very large PDFs (100+ pages, 50MB+) may load slower. For best performance, use our Split PDF tool to work on sections of very large documents.
