Frequently Asked Questions
Does Merge PDF upload my files to a server?
No. Merge PDF runs entirely in your browser using JavaScript and the Canvas API built into the browser itself — your files never leave your device or get sent to any Nabukit server.
Is it safe to use Merge PDF with confidential files?
Yes. Since processing happens entirely in your browser's memory and is never transmitted over the internet, there is no point where a confidential file could be intercepted, stored, or leaked by Nabukit — it simply never receives it.
Why is Nabukit's Zero-Server execution safer than traditional online tools?
Traditional tools require uploading your file to a remote server to process it, creating a copy outside your control. Merge PDF runs with your own browser's engine (JavaScript), so that copy never exists — no server can lose, expose, or retain your data, because it never receives it in the first place.
How many PDF files can I merge at once?
Up to 15 files per merge, with a proactive notice if you try to add more.
Can I merge a password-protected PDF?
Yes, by unlocking it first from within the same tool using its password. The result is rebuilt from high-quality images of each page (because the merging library can't decrypt PDFs) — the honest trade-off is that text stops being selectable/searchable in that specific file.
