PNG to PDF

What does the PNG to PDF tool do?

The FreePDF PNG to PDF tool converts one or more PNG images into a single PDF document. Each image becomes a page sized to the image's natural dimensions, and you can reorder pages before converting.

Conversion is performed in your browser with pdf-lib — your images are never uploaded to any server.

What FreePDF PNG to PDF can do

• Convert PNG images to PDF at original resolution
• Combine multiple images into one multi-page PDF
• Reorder images before converting
• Works entirely in your browser — no file uploads

Privacy — your files stay on your device

PNG to PDF runs entirely inside your browser using pdf-lib and PDF.js (Mozilla) — open-source, audited libraries with millions of users. Your files are loaded into browser memory, processed on your CPU, and written back out as a direct download. Nothing is sent to any server — you can verify this in your browser devtools → Network tab. Close the tab and everything is cleared from memory.

Supported devices and browsers

Known limitations

FreePDF is honest about what it can and cannot do:

• Very large images (50MB+) may be slow on mobile devices
• Animated formats are converted as a static frame
• Output is uncompressed — use Compress PDF for smaller files
