About PDF to image conversion
Slides and previews
Turning PDF pages into images helps embed previews in wikis, chat apps that do not render PDFs inline, or social posts with strict image-only uploads.
Pick a resolution that matches the display context: thumbnails need fewer pixels than print-ready artwork.
Fonts and rendering
Rasterization depends on font embedding. Missing fonts can substitute alternatives and change line breaks compared to desktop viewers.
When fidelity matters, open the PDF in an authoritative viewer first to confirm it looks correct before converting.
Archiving
Images lose selectable text unless you run OCR separately. Keep the original PDF when searchability or copy-paste matters.
Large multi-page conversions can be heavy on memory; process in batches for big documents.
