FAQ

Are my files uploaded anywhere?

No. The merge happens entirely in your browser using pdf-lib. We don't see your files and never could.

Is there a file size limit?

Only your browser's memory. Most modern devices handle 100+ MB combined easily.

Can I reorder individual pages, not just files?

Yes — see the PDF Reorder tool on the Hub for fine-grained page-level control.

Ready to use it?

Open the free PDF merger online on AroraLabs Hub. No signup, no email, no watermarks — just the tool.
