Does PDF merging work without uploading?

Yes. PDF processing occurs in the browser (client side), so there is no file upload and the data never leaves your computer.

Does the order and page orientation remain in the merged PDF?

Yes. The order you set with the handle or the up/down arrows and the original page orientation remain unchanged.

What is the difference between merge, combine and join?

There is no difference: they all refer to combining multiple PDFs into a single file.

Why is it secure? Most major providers use user data for their own purposes – personalisation, advertising or even training artificial intelligence models. We choose a different path: processing is entirely client-side. Your PDF never leaves your computer.
- No file uploads.
- No data sharing.
- No training on your documents.
- All operations run in your own browser.
