PNG images in a PDF: keeping screenshots and graphics sharp

PNG is a lossless image format, which means it stores every pixel exactly. That makes it the usual choice for screenshots, logos, diagrams and anything with text in it.

Turning PNGs into a PDF helps when you need to send several screenshots in order, such as steps to reproduce a software bug, evidence for a complaint or the pages of an online receipt.

Keep screenshots in the order they were taken. Phones and computers name them with the date and time, so sorting by name usually gives the right sequence.

Phone screenshots are tall and narrow. On a PDF page they appear smaller, with space at the sides. That is normal and keeps the whole screen visible.

Transparent areas, which are common in logos, show as white on the page. If you need a coloured background, add it to the image before converting.

PNG files can be large for photos, because lossless storage doesn't compress photographic detail well. For photos, JPG to PDF usually gives a smaller file.

Crop out personal details before you convert. Screenshots often include notifications, email addresses or account numbers at the top or bottom of the screen.

If the PDF is for a complaint or a dispute, keep the original PNG files as well in case someone asks for them.

Need to go the other way? PDF to PNG turns each page of a PDF back into a sharp image.

When you send screenshots as a PDF, add a short note saying what each page shows. It saves the reader guessing.

When to use PNG to PDF

Use PNG to PDF for screenshots, diagrams and graphics with sharp edges or text. PNG keeps those details crisp, and the PDF keeps them that way.
