Frequently Asked Questions

Can I edit existing text in a PDF?

Yes. Click a line of the document's own text and type. The editor rewrites it inside the file and keeps the original font, size and colour, all in your browser. Two limits worth knowing: it works line by line rather than reflowing paragraphs, and if the document's font lacks a character you type, that line is set in a substitute of the same width and the editor tells you. You can still add new text, highlights, drawings and shapes on top as well.

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.

Does whiteout permanently remove the text underneath?

It depends on the text. When a whole run of text sits inside the box, the editor deletes it from the file, so the words are gone and not just hidden. When the text carries on past the edge of the box it is covered instead, because removing it would delete words you never selected: the original then stays in the file and can be found with copy and paste or a text extraction tool, and the editor tells you so when you save. For a guarantee, use Redact PDF, which turns the affected area into an image.

💡

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