PDF editing lets you add visual marks, drawings, text, highlights, and redactions directly to your PDF pages.
This browser tool includes Draw, Text, Highlight, and Redact modes so you can mark up documents, call out important sections, and obscure sensitive areas before export.
Editing a PDF online is useful when you need to review a document quickly, add notes, mark issues, or hide sensitive content before sharing it.
It also avoids the need to install extra software when you only need a fast browser-based markup workflow.
Use Draw for freehand markup, Text for short comments, Highlight for emphasis, and Redact for obscuring sensitive areas before export.
The page editor lets you move through the PDF pages, adjust brush color and width, and keep your changes local in the browser.
Select a PDF file from your computer. All pages are rendered for editing.
Use Draw, Text, Highlight, or Redact depending on the markups you need.
Draw directly on the page preview and navigate between pages as needed.
Download a new PDF with your edits applied to the edited pages.
A project manager reviews a PDF design proof, highlights key sections, draws arrows to problem areas, adds brief text notes, and redacts a private client detail before sending the marked-up PDF to the team.
Can I edit existing PDF text?
This tool is designed for annotations, highlights, drawings, redactions, and text overlays. Editing existing embedded PDF text may not be supported for all documents.
Are redactions permanent?
Redacted areas become part of the exported page image and are visually obscured in the downloaded PDF.
How many pages can I annotate?
Most PDFs can be previewed and annotated directly in the browser. Very large documents may take longer to load depending on your device.
Is my PDF uploaded?
No. Loading, previewing, editing, and exporting happen locally in your browser.
Can I add text notes?
Yes. Select Text mode, click a page, and enter the text to place at that position.
Will the PDF remain a PDF?
Yes. The download is a standard PDF file with edited pages included.
Can I use this to redact sensitive information?
Yes. Redact mode visually obscures selected areas in the exported PDF. Always verify the exported file before sharing sensitive information.
