PDF Highlighter by PDF Highlighter

Open local PDF files and direct PDF links in the PDF Highlighter web app.

PDF Highlighter helps you:
- Highlight text and add comments
- Draw, add text, shapes, signatures, and images
- Search documents and navigate highlights
- Translate selected text and use optional AI tools
- Open PDF links from the context menu or automatically

Local PDFs up to 100 MB are transferred directly from the extension to the PDF Highlighter tab. The extension does not upload document contents to its own server. Automatic PDF opening is optional and can be disabled at any time.
