FAQ

Are my PDFs uploaded to a server?

No. All PDF merging and splitting happens in your browser using the pdf-lib library. Your files never leave your device.

Is there a file size or page limit?

There are no artificial limits. Since processing happens locally, the only constraint is your device's available memory. Very large PDFs (100+ MB) may take a few seconds to process.

Does it add watermarks to the output?

No. The merged or split PDF is clean — no watermarks, no branding, no modifications to the original content.

Can I reorder pages when merging?

Yes. You can drag and drop files to reorder them before merging. The final PDF will have pages in the order you arrange.
