Architecture & Privacy Analysis
PDF24 publishes online tools and a desktop application. The desktop app is a genuine local option, and the breadth of their tools is why people recommend them. The online side uploads if that is the side you use. This page does not blur the two products or guess their current terms. Evaluate the desktop app if you want an installer. Use this site if you want the browser you already have, with no upload and a narrower list of finished jobs. Last reviewed 2026-09-27.
PDF24 alternative stays on this device. The download is the copy you keep, and Weesize does not store a second one. Close the tab when you are finished and the bytes are gone.
Key Architectural Points
- No upload on this site: the file is not the price of the tool.
- PDF24’s strength is stated without a slogan war.
- Unfinished jobs are labeled, not imitated.
