PDFescape

PDFescape is a veteran free, web-based PDF editor that has served users for basic editing needs for over a decade. Its primary appeal is providing genuine PDF editing capabilities—such as adding, modifying, and deleting text, inserting images and shapes, and creating form fields—directly in a browser without any cost or watermark. It also offers a downloadable desktop version for offline use with more features. The interface is functional though dated, and the free online version is supported by ads.

While it lacks OCR, advanced security, and the polish of modern editors, it successfully fills the niche for users who absolutely need to edit text in a PDF for free and cannot or will not install software. It's a practical, no-frills workhorse for students, freelancers, and anyone in a pinch.
