Got Questions?

Frequently Asked Questions

Fact-based answers regarding merge pdf capabilities, security, and format support.

Is there a limit on how many PDF files I can merge?

There are no arbitrary file count limits. Because merging runs in your browser's local memory, you can easily combine dozens of PDFs up to 100MB+ total.

Can I merge password-protected PDF files?

If a PDF is protected by an open password, you should first unlock it using the Unlock PDF utility before merging.

Are page text layers and vector graphics preserved during merging?

Yes. Page graphics, vector text, embedded fonts, and visual content streams are copied directly into the merged document without re-compression.

Are my confidential contracts or reports uploaded to a server?

No. The entire merge process executes locally in client-side WebAssembly RAM. Your files never leave your computer.
