Explanation

Dexify signs PDFs entirely in your browser. Upload a PDF, draw/type/upload a signature, place it on the preview, and stamp it across selected pages. Because everything runs locally with PDF-Lib, documents and signatures never leave your device.

Use typed signatures with color and size controls, or upload a transparent PNG/JPG for brand marks. Adjust X/Y offsets and scale, and preview placement before exporting a clean, watermark-free signed PDF.

The controls match other Dexify tools—chips, upload area, and consistent buttons—so moving between sign, protect, or compress feels seamless.
