WrenPDF

PNG to PDF

Convert PNG screenshots and graphics to PDF at lossless quality. Files never leave your browser.

What it does

Screenshots, diagrams and logos are sharp-edged PNGs, and JPEG compression can smear them. This page picks Lossless quality by default, so text and lines stay crisp in the PDF.

How to use it

  1. Drop your PNG files.
  2. Reorder them; quality is preset to Lossless (PNG).
  3. Press "Create PDF".

When is it useful?

  • Building a bug report or how-to guide from screenshots
  • Sending diagrams as a PDF attachment
  • Sharing design mock-ups with a client

Tips

  • If the file is too large, switch quality to High; the difference is rarely visible.
  • Transparent areas appear white on the PDF page.

Frequently asked questions

Is transparency kept?
PDF pages have a white background, so transparent areas show as white.
Why is the file bigger than with JPG?
Lossless PNG keeps every pixel as it is. For a smaller file, set quality to High or Medium.
