PDF Locker & Tools

About

PDF Locker & Tools is a Chrome extension for people who need a few practical PDF actions without opening a heavy desktop app or uploading files to a website.

Use it to lock PDF files with an owner password, merge multiple PDFs into one file, split one PDF into range-based outputs, or extract selected pages into a new PDF. The extension runs inside Chrome’s side panel and is built for simple, local PDF work.

This extension is a good fit if you are looking for a PDF locker, PDF merge tool, PDF splitter, or PDF page extractor that works directly in Chrome. It is designed for lightweight document tasks, not full PDF editing.

Current shipped tools:
- Lock PDFs
- Merge PDFs
- Split PDFs by page range
- Extract selected pages into one output PDF

The extension processes user-selected files locally in Chrome and saves outputs with Chrome’s download flow. It also stores your tool settings locally, so you do not need to re-enter them every time.
