- Click "Add Annotation" to preview the placement, then add more annotations as needed.
- Click "Download Annotated PDF" to save the finished document.
Why use Formfy's PDF editor?
Unlike web-based tools that upload your documents to a server, Formfy's PDF editor runs entirely in your browser using the pdf-lib library. Your PDFs are processed locally and never transmitted over the internet — making it ideal for sensitive documents like contracts, medical records, or legal paperwork.
Text annotations are permanently embedded into the PDF output, so they appear correctly in every PDF viewer without requiring fonts or special software. Annotations are not sticky notes — they are real text written directly onto the page.
Frequently Asked Questions

What can I annotate on a PDF?
You can add text in any color, size, and position on any page. Choose the page, set X/Y position as percentages, and pick your font size.
Are my files uploaded to a server?
No. The PDF editor runs entirely in your browser using pdf-lib. Your files never leave your device.
