What does PDF to PNG do?

It renders each page of your PDF as a lossless PNG image. You choose the DPI. Multiple pages are bundled into a ZIP download.

Is my PDF uploaded to a server?

No. Everything runs in your browser. Your file never leaves your device.

Why use PNG instead of JPG?

PNG is lossless — no compression artifacts. It’s better for text-heavy pages, diagrams, screenshots, and anything where sharp edges matter. JPG is smaller but lossy.

The file sizes are large. Is that normal?

Yes. Lossless means nothing is thrown away. A 300 DPI full-page PNG can be several megabytes. If size matters more than quality, use PDF to JPG instead.

Can I convert specific pages only?

Yes. Enter a page range like "1-5, 8" to export only the pages you need.

Does it work with password-protected PDFs?

Yes. You’ll be prompted for the password. Decryption happens locally.

What DPI should I pick?

72 for screen previews, 150 for general documentation, 300 for high-quality print or archival.

Can I use this on mobile?

Yes. Works in any modern mobile browser. Same features, same privacy.

About PDF to PNG

How PDF to PNG Export Works

Each PDF page is rendered at your chosen DPI and saved as a lossless PNG image. No quality slider here — PNG is lossless by definition, so what you see is what you get. One page produces one PNG file. Multiple pages download as a ZIP.

The rendering runs in your browser. Your PDF never goes to a server. Pick your pages, pick your DPI, and download.

When PNG Is the Right Choice

PNG exists for situations where JPEG compression would ruin the output. If you need sharp text, clean lines, or transparency, PNG is the format.

Documentation & Screenshots

Technical docs, code samples, and UI mockups have sharp edges and small text. PNG preserves every pixel without compression artifacts.

Design Assets

Extract diagrams, illustrations, or icons from a PDF design deck. PNG keeps colors accurate and edges clean for reuse in design tools.

Archival Quality

When you need a pixel-perfect record of a PDF page — for legal evidence, regulatory compliance, or long-term archiving — lossless PNG is the safe bet.

Image Editing

PNG is the starting point for further editing in Photoshop, GIMP, or Figma. Unlike JPEG, you won’t pile compression artifacts on top of your edits.

DPI and File Size

PNG files are larger than JPEGs because they don’t throw away data. At 300 DPI, a full-page PNG can be 2–10 MB depending on the content. If file size matters more than lossless quality, use the PDF to JPG tool instead.

72 DPI works for quick screen previews. 150 DPI is good for documentation. 300 DPI gives you print-quality output.

Privacy: Processed Locally

Your PDF is rendered in your browser. Nothing gets uploaded to a server. Close the tab and the temporary image data is gone. This matters when your PDFs contain confidential information, proprietary designs, or personal data.
