How to edit a PDF (add text, highlights and shapes) on Windows
You don't need special software to edit a PDF (add text, highlights and shapes) on Windows. FernPDF runs entirely in Edge or Chrome on Windows: open the tool, drop your file, download the result. The whole editor runs in your browser: rendering, editing and saving all happen on your device.
No desktop installer, no admin rights, no paid software. It works on locked-down work laptops because it's just a web page. Windows 10 and 11 are both fine.

2Drop the PDF you want to change.
3Add text boxes, highlights, shapes, images or whiteout, or switch to Edit text mode to rewrite existing lines.
