Practical help with everyday PDF jobs
Short, honest explanations of the problems people actually hit with PDFs: why a file won’t go under an upload limit, how to merge or unlock documents without handing them to a server, which resolution to pick when turning pages into images, and what an “e-signature” really proves.

PDFMagpie’s tools are deliberately simple, but the questions around them often aren’t. Why did compression barely change my file? Is a signature image legally valid? Which page size should photos go on? We’d rather explain the trade-offs plainly than promise things a tool can’t do. Every guide is written for people, checked against how our tools actually behave, and updated when they change.
