How It Works
Drop your PDF file
Drag and drop or select a PDF document. Works with any PDF — text documents, scanned pages, technical drawings, forms.
High-res rendering at 2x
Mozilla's pdf.js renders the page at 2x device resolution onto a Canvas. Text stays razor-sharp, line art crisp, graphics detailed.
Lossless PNG export
The Canvas exports as a 24-bit PNG with DEFLATE compression. Unlike JPG, there are zero compression artifacts — every pixel is preserved exactly as rendered.
Download pixel-perfect image
Your PNG is ready. Perfect for documents with fine text, diagrams, or technical drawings where JPG artifacts would be unacceptable.
// under the hood
Mozilla's pdf.js renders the PDF onto a Canvas at 2x resolution for high-DPI display quality. The canvas is exported as a 24-bit PNG with lossless DEFLATE compression via toBlob. Unlike JPG output, PNG preserves every rendered pixel without compression artifacts — ideal for text-heavy documents and line art. File sizes are larger than JPG but quality is perfect.

Frequently Asked Questions
- Why choose PNG over JPG for PDF conversion?
- PNG uses lossless compression, so text and line art stay perfectly sharp with no compression artifacts. This makes PNG ideal for documents, diagrams, and anything with fine detail. JPG is better when you need smaller file sizes for photos.
- How does the conversion work?
- We render your PDF at 2x resolution using Mozilla's pdf.js library, then export the canvas as a lossless PNG image. Everything runs in your browser — no server involved.
- Does PNG support transparency?
- Yes, PNG supports transparency. However, PDF pages are rendered with a white background by default, so the output will have a white background rather than transparency.
- Will the file size be large?
- PNG files for document pages are typically 1-5MB depending on the page content and complexity. Pages with mostly text compress well in PNG. Photo-heavy pages will produce larger files — consider JPG for those.
- Are my documents private?
- Completely. Your PDF never leaves your device. All processing happens locally in your browser using open-source pdf.js technology. We have zero access to your files.
