Picking the Right Image Format
PNG preserves sharp edges for UI and iconography, making it the go-to for design reviews.
JPG is better for brochures or photo lookbooks where subtle gradients matter more than pin-sharp text.
Managing DPI and Output Size
Use 96 DPI for web previews, 150 DPI for slide decks, and 300 DPI when sending to printers.
PDFTools shows the estimated file size per page so you can tweak DPI before exporting a large batch.
Preserving Transparency
Enable the "Keep transparency" toggle when exporting PNGs so overlays or sticker-style assets render correctly.
When transparency is unchecked, PDFTools fills the background with your chosen hex code.
Conclusion
Exporting PDF pages to high-resolution images is a great way to create a visual representation of your document. By picking the right image format, managing DPI and output size, and preserving transparency, you can ensure that your images are clear and professional.
