Frequently Asked Questions
Common questions about our PDF editor
Is this PDF editor free?
Yes, our Edit PDF tool is completely free. You can add text, images, signatures, highlights, drawings and watermarks to your PDF files without any cost or subscription.
Are my files secure?
Absolutely. All editing happens entirely in your browser using client-side technology. Your files are never uploaded to any server.
Can I add a signature to my PDF?
Yes. Use the Signature tool to draw your signature with a mouse or finger, or type your name in a handwriting-style font, then place it anywhere on the document.
Can I highlight text or draw on my PDF?
Yes. The highlighter works like a digital marker pen, and the draw tool lets you sketch freehand in any color and stroke width.
Can I edit the text or move images that are already in my PDF?
Yes. Switch to the Select tool and drag any line of the original text or any image to move it. Click a text line to select it, then click it again (or press the Edit button) to change its content — the replacement keeps the original font style and is applied when you download the file. Original images can also be clicked, dragged, resized or deleted. This works for digitally created PDFs; scanned documents (photos of pages) contain no text layer to select.
Can I manage pages — rotate, delete, duplicate or reorder them?
Yes. Rotate pages 90 degrees at a time, duplicate or delete pages, add blank pages, and reorder pages by dragging thumbnails in the page panel.
Can I undo or redo my changes?
Yes. Use the Undo and Redo buttons in the toolbar or the keyboard shortcuts Ctrl+Z and Ctrl+Y. Your session is also auto-saved in your browser in case you reload by accident.
Does it work on mobile?
Yes. The editor is fully mobile responsive with a bottom toolbar you can swipe between (Edit, Annotate, Shapes, Pages, More), pinch-to-zoom, and touch-optimized drag, resize and drawing.
Can I open password-protected PDFs?
You can open password-protected PDFs by entering the password when prompted. Note: saving an encrypted PDF with edits requires the export feature to support re-encryption, which is not available yet.
