PDF (Portable Document Format) is the most widely used document format in the world. Whether you are a student submitting coursework, a professional sharing reports, or someone filling in a form, PDFs are everywhere. Knowing how to edit, merge, and annotate them saves time and removes the frustration of working around a format you cannot change.
Traditionally, editing PDFs required expensive desktop software like Adobe Acrobat. Modern browser technology — specifically WebAssembly and powerful JavaScript PDF libraries — now makes it possible to do everything locally, inside your browser tab, at no cost.
These guides walk you through the most common PDF tasks using PDF Genie Online, a free, private, browser-based editor. No downloads, no account, and your files never leave your device.
