Why it's private
This tool uses the open-source pdf-lib library running as JavaScript in your browser tab. Your files are read locally, merged locally, and never sent to a server — so it works even with sensitive documents like contracts or ID scans.
❓ FAQ
Frequently Asked Questions
Is merging PDFs with Doxify really free?▾
Yes — 100% free, no signup, no watermark, and no limit on how many times you use it.
Can I control the order the PDFs merge in?▾
Yes. Files merge top-to-bottom as listed. Use the ↑ / ↓ buttons next to each file to reorder before merging.
Is there a limit on file size or number of PDFs?▾
No hard limit is enforced, but very large files depend on your device's memory since everything runs in your browser.
Does Doxify upload my PDFs to a server?▾
No. All merging happens locally in your browser using the pdf-lib library. Your files never leave your device.
