Frequently asked questions

How do I edit a PDF for free online?
Upload your PDF — the editor opens in your browser. Add text boxes, highlight content, draw shapes, add signatures, and annotate. Download the edited PDF when done.
Can I change the text in an existing PDF?
Yes — you can add text boxes on top of existing content. Directly editing embedded text requires the original source file or the PDF to Word converter.
Can I highlight text in a PDF for free?
Yes. Use the highlight tool to select and colour text. Highlight colour and opacity are adjustable.
Does the free PDF editor add a watermark?
No. pdftoolz does not add watermarks to edited PDFs. Your output contains only your original content and any edits you made.
Can I add a text box to a PDF?
Yes. Select the Text tool, click anywhere on the page, and type. Resize, reposition, and style the text box as needed.
How do I add a signature to a PDF?
Use the Sign PDF tool for a dedicated signature experience — draw, type, or upload your signature and place it precisely on the document.
