How to merge multiple PDFs

I built CarePDF because I was tired of uploading my private documents to random websites just to merge a few pages together. I wanted something that worked locally in my browser.
How it works
The PDF merging tool runs entirely on your device. When you drag and drop your files, JavaScript processes them locally using PDF.js. Your files never hit my server.
- Add your files: Drag and drop your PDFs into the box.
- Order them: Click and drag the thumbnails if you need to rearrange them.
- Save: Click "Merge PDF" and the browser will download the combined file.
That's it. It's simple, fast, and completely private.
