Why turn a PDF into images?
Images are easier to share in chats and social media, to place in presentations and to upload to sites that do not accept PDF. Turning pages into pictures is also the quickest way to show part of a document without sending the whole file.
The PDF is read and drawn in your browser, so contracts, invoices and scanned documents never leave your device.
Which resolution should you choose?
Low (72 DPI) is enough for previews and thumbnails. Medium (150 DPI) works well for screens and most documents. High (300 DPI) keeps small text sharp and is the right choice for printing, although the files are larger.
