PDF Merger
How to merge PDF files
- Select multiple .pdf file(s) using the drop zone or file picker.
- Wait for client-side processing to finish in your browser.
- Download the combined .pdf result.
Why convert locally?
Your .pdf files are processed entirely in browser memory. Nothing is sent to a server, stored in a database, or retained after you close the tab. This makes local conversion ideal for sensitive data, proprietary configs, and private media.
