Practical guide
PDF to JPG versus PNG
Both formats turn a PDF page into pixels, but they optimize for different kinds of content.
Published and reviewed
Choose JPG for smaller photographic images
JPG uses lossy compression and is usually a practical choice for photos, previews and web sharing where modest quality loss is acceptable.
Choose PNG for crisp lines and text
PNG uses lossless compression and often preserves screenshots, diagrams and sharp text edges better. The trade-off is a larger file, especially for complex pages.
Resolution matters
FileSwift uses a render-scale setting. A higher value creates more pixels, improves detail and increases memory use and ZIP size. Start with the default and increase only when the output is not sharp enough.
What both formats lose
Neither JPG nor PNG preserves selectable text, PDF links, forms, bookmarks or other interactive document features. Keep the original PDF when those features matter.
