Frequently Asked Questions

Can I edit existing text in a PDF?

HonestPDF lets you add new text, highlights, drawings, and shapes on top of any PDF. Editing the original embedded text is not supported in browser-based tools. For that, first use HonestPDF's PDF to Word converter.

Will my edits show up in Adobe Acrobat and other readers?

Yes. All annotations are rendered into the final PDF as standard page content, so they appear in Adobe Acrobat, macOS Preview, Chrome PDF viewer, and every other PDF reader.

Is there a watermark on the output PDF?

No. HonestPDF never adds watermarks to your edited PDFs. It is completely free without any hidden catches or stamps.

Is my PDF uploaded to a server?

No. Your PDF never leaves your device. All editing and rendering happen entirely in your browser using JavaScript. This makes HonestPDF the most private PDF editor available.

Can I add images to my PDF?

Yes. Use the image tool to upload and place images anywhere on any page. You can resize and position them after placing them. Supported formats include PNG, JPEG, and SVG.

How do I undo a mistake?

Press Ctrl+Z (or Cmd+Z on Mac) to undo, and Ctrl+Shift+Z to redo. You can also use the undo/redo buttons in the toolbar. The full history is maintained until you download.

What drawing tools are available?

The editor includes a freehand pen, highlighter, shapes (rectangle, circle, arrow, line), text tool, sticky notes, and whiteout. Each tool has adjustable color and thickness.

Can I edit a password-protected PDF?

You need to remove the password protection first. Use HonestPDF's Unlock PDF tool to remove the password, then open the unlocked file in the editor.

Can I edit multiple pages?

Yes. Navigate between pages using the thumbnails. Each page has its own annotation layer, and all changes across all pages are included in the final download.

Does it work on my phone?

Yes. The editor is mobile-friendly and supports touch gestures on iOS Safari and Android Chrome, including pinch-to-zoom and drag-and-drop annotations.

Once you have edited your PDF, you might want to sign it or compress the final file before sharing.
