Frequently Asked Questions (FAQ)
Is my PDF uploaded to a server during conversion?
No. ConverterMaster processes all PDF files locally inside your browser using JavaScript and HTML5 Canvas. Your document data is never sent to any external server.
How does the Transparent Background option work?
When 'Enable Transparent Background' is enabled, the converter avoids drawing a solid white background behind your PDF pages, producing PNG images with transparent alpha channels ideal for graphic design and overlays.
What is the difference between 300 DPI, 150 DPI, and 72 DPI?
Ultra 300 DPI renders pages at double canvas resolution for high-definition printing. High 150 DPI provides balanced web performance. Standard 72 DPI yields smaller file sizes for fast transmission.
What is the maximum supported PDF file size?
Because processing uses client-side browser RAM, files up to 50MB and hundreds of pages convert smoothly on standard modern desktop and mobile browsers.
Choosing Settings for Sharp, Reasonably Sized PNGs
PNG is lossless, so every page you export keeps its sharpness, but file size grows quickly with resolution. A few practical choices keep the results useful without filling your downloads folder.
Match the resolution to the purpose
- On-screen use, chat or documentation: the 72 DPI preset is usually enough and gives the smallest files.
- Web pages and presentations: the 150 DPI default keeps text readable when images are scaled down a little.
- Print, posters or detailed diagrams: use the 300 DPI preset, and expect noticeably larger files.
Higher resolution means more pixels per page, so a long document at the top setting can be slow. Test one page first.
When PNG is the right format, and when it is not
PNG suits pages with text, line art, charts and logos, because sharp edges stay clean. Full-page photographs make very large PNGs. If you are exporting photo-heavy pages for the web, the PDF to JPG converter will usually produce much smaller files.
Using transparency well
Transparency only helps when the page itself has no solid background. Many PDFs paint a white rectangle behind the content, and then the output still looks white. Check logos and vector art on a dark background to spot leftover white edges.
Common problems
- Blurry text: raise the DPI preset and make sure you view the PNG at 100%.
- Browser slows down: convert a smaller page range.
