Key features
Private by design: how this converter works
Unlike typical online converters that upload your file to a remote server, this Merge PDF converter processes everything on your own device using PDF.js (by Mozilla), pdf-lib and other open-source libraries compiled for the browser. Your file is read into browser memory, converted, and offered back as a download — it is never sent to us.
- No upload wait — conversion starts instantly, even on slow mobile data.
- Private — safe for NID copies, certificates, bank statements and personal photos.
- No limits — no daily quota, no queue and no watermark.
- Offline-ready — once loaded, many tools keep working without internet.
