PDF Editor lets you mark up a PDF without any software. Add text boxes, draw freehand, highlight areas and drop in images directly on the page, then save a new PDF. Your edits are drawn onto the original pages using pdf-lib while the existing content is preserved. Everything runs locally in your browser, so your document is never uploaded and stays completely private.
Whether you need to fill in a form, sign a contract, redact a detail or add a quick note before sending a document on, this free online PDF editor gives you the essentials without the cost or complexity of desktop software. Pick the text, draw, highlight or image tool, click anywhere on the page, and your change is placed exactly where you want it. You can reposition or delete anything you add until the document looks right, then export a fresh PDF that keeps every original page intact.
Because everything is handled in your browser with the open-source pdf-lib library, your file never leaves your device and nothing is stored on a server. That makes it a safe choice for sensitive paperwork such as tax forms, agreements and internal reports. It runs on Windows, macOS, Linux, Android and iOS in any modern browser, so you can edit a PDF online on your laptop or annotate one on your phone without installing an app or creating an account.
