What is Merge PDF?

Merge PDF is a free, browser-based tool that lets you edit and manage PDF files using the merge pdf in seconds — no software installs, no account, and no file size limits for typical use. Everything runs locally in your browser tab, so your content is never uploaded to a server, making it fast, private, and safe to use for work or personal projects.
