Frequently Asked Questions

Can I merge PDFs without uploading them?

Yes! MagicKit processes all PDFs directly in your browser using pdf-lib. Your files never leave your device.

Is there a file size limit?

No strict limit. Since processing happens in your browser, larger files may take longer but there's no server-imposed restriction.

Will the PDF quality be reduced?

No. MagicKit preserves the original quality of your PDFs. Compression is only applied when you explicitly choose it.

Can I process password-protected PDFs?

Yes, use our PDF Unlock tool to remove passwords, or enter the password when prompted in other tools.
