Frequently Asked Questions
Why convert PDF to PNG instead of JPG?
PNG is a lossless format — every pixel is stored exactly as rendered, with no compression artifacts. This makes it ideal for PDFs with sharp text, technical diagrams, charts, or screenshots where quality must not degrade. JPG is better suited for photographs where smaller file size matters more than pixel-perfect accuracy.
What DPI should I use for PDF to PNG conversion?
72 DPI is fine for web display and email attachments. 150 DPI gives a good balance of quality and file size for most uses. 300 DPI is the standard for print — it produces the largest files but the sharpest output, suitable for professional printing.
How large are PNG files compared to JPG?
PNG files are significantly larger than JPG because they are lossless. A single A4 page at 150 DPI is typically 1–3 MB as PNG versus 100–300 KB as JPG. At 300 DPI, PNG files can exceed 10 MB per page.
Does PDF to PNG support transparency?
PDF pages are rendered on a white background before export. Standard PDF content (text, images, graphics) will look identical. True page-level transparency is not preserved — transparent areas become white, matching standard PDF viewer behavior.
Is my PDF safe to convert online?
Completely safe. All conversion happens locally in your browser using PDF.js (WebAssembly). Your file is never sent to any server. We have zero access to your documents.
Can I convert a scanned PDF to PNG?
Yes. Scanned PDFs are image-based and convert quickly. Since the source is already a rasterized image, the output PNG quality will match the original scan resolution. Use 150 or 300 DPI to capture all detail.
What is the maximum PDF size I can convert?
There is no hard file size limit — processing happens entirely in your browser. Most devices handle PDFs up to 100 MB without issues. Very large PDFs at 300 DPI may be slow on older hardware due to canvas memory requirements.
