PNG to PDF

PNG is the format of choice for graphics, diagrams, screenshots, and images with transparency. The PNG to PDF converter embeds your PNG files into a PDF document at full quality, making them easy to share, print, or archive in a universally readable format.

Transparency handling is a key distinction between PNG to PDF and JPG to PDF. When a PNG has transparent areas (saved with an alpha channel), those areas are composited over a white background in the PDF — which ensures the document prints correctly and displays consistently in all PDF readers. The PNG image data itself is embedded losslessly, so every pixel is preserved exactly as in the source file.

When to choose PNG to PDF over JPG to PDF:

• Converting UI screenshots or wireframes that contain crisp text and sharp edges
• Embedding logos or graphics that originally used a transparent background
• Compiling technical diagrams, flowcharts, or architectural drawings
• Submitting design mockups for review in PDF format

You can combine multiple PNG files into a single PDF — a useful shortcut when you have a multi-page diagram saved as separate PNG exports. Files are placed in the order they are selected, so pick your images in the desired page sequence before clicking convert.

The resulting PDF can be further processed: use Compress PDF if the file size is larger than needed for emailing, or Merge PDF to combine it with an existing document.

Privacy: All uploaded files are processed over HTTPS and automatically deleted from our servers within one hour. No account is required and the conversion is completely free.
