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.
