PNG preserves the rendered pixels, not the PDF structure
Each page is drawn to a browser Canvas at 2× scale and saved as PNG. That encoding is lossless, but the output still has fixed dimensions and contains no selectable text, hyperlinks, form controls, or original vector objects.
Best-fit pages
Choose PNG for diagrams, UI mockups, sheet music, typography samples, line drawings, or pages you plan to annotate. For photo-heavy pages and smaller sharing files, JPG may be more practical.
Steps and checks
- Add an unencrypted PDF.
- Choose First page or All pages.
- Convert and inspect dimensions and small text before downloading each result.
Large-output troubleshooting
Lossless PNG can consume substantial memory and storage for long or photographic documents. Split the document, close other heavy tabs, or use PDF to JPG when smaller page previews matter more than lossless pixels.
PDF-to-PNG questions
Why use PNG for PDF pages?
PNG avoids additional lossy artifacts, which can help text edges, diagrams, interface captures, and line art remain crisp at the rendered resolution.
Will PNG files be larger than JPG?
Often, especially for photographic or colour-rich pages. Actual size depends on page content.
Does PNG make vectors resolution-independent?
No. The PDF page is rasterized at twice its display scale. The PNG is lossless at those fixed pixel dimensions but is no longer vector artwork.
Can I export a selected page range?
The current workflow supports the first page or all pages, not a custom range. Split the PDF first when only a middle range is needed.
Are pages processed locally?
Yes. The PDF and generated PNG data remain in the browser workflow.
