About This Tool

Designers and developers who need crisp page images with sharp text edges, people who want screenshots of PDF pages, and anyone who needs transparency preserved.

Input: PDF  ·  Output: PNG (ZIP).

Features and Limitations

Features

  • Lossless PNG output with crisp text.
  • Optional transparent background.
  • Pages rendered and released one by one to save memory.
  • Resolution from 72 to 300 dpi.

Limitations

  • PNG files of full pages are much larger than JPG; 300 dpi A4 pages are often several megabytes each.
  • Very large pages are scaled down automatically to stay within the browser canvas limit (about 25 megapixels).
  • Most PDFs paint a white page background themselves, so transparency only appears where the PDF leaves areas unpainted.
  • Password-protected PDFs must be unlocked first.
  • Processing happens on your device, so very large files depend on your browser's available memory.

Example

Page 1 of an A4 PDF at 150 dpi becomes a 1240 × 1754 pixel PNG named document-page-1.png.

Frequently Asked Questions

PNG or JPG: which should I choose?

Choose PNG for text, diagrams and screenshots because it stays sharp. Choose JPG for photo-heavy pages when a smaller file matters more than perfect edges.

Why is my background still white when I enable transparency?

Many PDFs draw a white rectangle behind the content, and that is part of the page. Only unpainted areas become transparent.

Can I convert a single page?

Yes. Enter one page number and you will receive one PNG without a ZIP.

Are my PDFs uploaded to a server?

No. The work is done by JavaScript libraries running inside your browser tab, so the file never leaves your device. Closing the tab discards everything.

Can I process a password-protected PDF?

Not directly. Browsers cannot open encrypted PDFs without the password, so the tool stops with a clear message naming the file. Remove the password first with our PDF Unlock Utility (you need to know the password and be allowed to remove it), then come back.
