When an image is more useful than a PDF
A PDF is the best way to keep a whole document. An image is better when a page has to go somewhere a document cannot, or when people will look at it on a screen rather than print it. PNG is the right choice when you want to:
- post a flyer or event poster on Facebook, Instagram, X or LinkedIn;
- send a page in WhatsApp, Messages or Teams, where it shows inline instead of as an attachment;
- put a page on a website, in a blog post or in an email newsletter;
- drop a page into a PowerPoint, Keynote or Google Slides presentation;
- keep a picture of a certificate or card in your photo library.
Why PNG keeps text sharp
Publisher documents are mostly text, lines and flat areas of colour. PNG stores those exactly, pixel for pixel, so small print and thin rules stay crisp however many times the image is opened, edited or saved again. JPG is designed for photographs and slightly blurs the edges of text to make files smaller.
If a website or form only accepts JPG, or you want smaller files to email, use the PUB to JPG converter instead. It is the same tool with JPG selected.
Standard or high quality
Standard renders pages at 110 dpi, about 935 by 1210 pixels for a US Letter page. That is sharp on phones, laptops and social media, and keeps files small.
High renders pages at 200 dpi, about 1700 by 2200 pixels for the same page. Choose it when you will print the image, zoom into fine detail, or crop part of a page.
Choose the quality before you upload. If you picked the wrong one, upload the file again; it only takes a few seconds.
One image per page, in order
A four-page newsletter gives you four images, named after your file with page-1 to page-4 on the end, so they stay in order when you download them all. Use "Download this page" for a single page, or "All pages as PNG" to get every page in one ZIP.
Each image shows the full page as it would print, including its background colour, at the page size the document was designed for.
Need the whole document too?
The same upload also makes a PDF, so you can download both without converting twice. See PUB to PDF for what the PDF keeps.
