Screenshots as PDF and sharp images: formats and quality
A screenshot is only useful if it's readable and in the right format. These guides cover PDFs both ways (a web page to PDF, and a PDF to an image) and how to keep text sharp.
PNG vs JPG for screenshots: PNG keeps text and edges sharp without loss, JPG makes smaller files for photos. When to use each, and when PDF is the better pick.
Turn a webpage into a PNG image of the whole page: with a Chrome extension, Chrome DevTools, Firefox or Edge, and why online converters miss pages you log into.
How to take a high resolution screenshot: why screenshots look blurry, how zoom and PNG help, and how Chrome DevTools' device pixel ratio gives 2x or 3x images.
