Frequently asked questions

Is there a limit on how many PDFs I can merge?

No limit. You can merge as many PDFs as needed. Very large batches may need a device with more RAM.

Will merging reduce quality?

No. Pages are copied directly without re-encoding. Image quality and text are fully preserved.

Can I merge password-protected PDFs?

Use the Unlock PDF tool first to remove the password, then merge.

Are my files sent to a server?

Never. All processing happens inside your browser. Files never leave your device.
