Frequently Asked Questions

Can I edit existing text in a PDF?
Yes. Choose Edit text, click a paragraph of the document's own text twice, and type. The editor rewrites it inside the file and keeps the original font, size and colour, all in your browser. Two things worth knowing: a paragraph of several lines reflows at word boundaries and keeps its alignment, and if the document's font lacks a character you type, that word is set in a substitute font; if no available font can draw it, the editor tells you and does not save. 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 and WebAssembly. This makes HonestPDF the most private PDF editor available.
Can I add images to my PDF?
Yes. Use the image tool to pick an image and place it anywhere on any page. You can resize and reposition it after placing it. Supported formats are PNG, JPEG and WebP.
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, text highlighting, shapes (rectangle, ellipse, arrow, line), a text tool, images and whiteout (a rectangle with a white fill and no outline). Shapes and the pen have adjustable color and thickness; text has color, font and size.
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 drag-and-drop annotations.
Does whiteout permanently remove the text underneath?
No. Whiteout is a white box drawn over the page: the text underneath is covered, not removed, so it stays in the file and can be found with copy and paste or a text extraction tool. To take words out of the file itself, delete them with the Edit text tool. For a guarantee, use Redact PDF, which turns the affected area into an image.
