Why Luleit's PDF Merger is Different

Frequently Asked Questions

Where do my PDFs go when I merge them?+

Nowhere. The merge happens in your browser using JavaScript — your files never touch our servers, never get uploaded, never get stored. Once you close the tab, the files are gone from memory; we have no copy. There is nothing for anyone to subpoena, breach, or sell.

Is this PDF merger really free, with no catch?+

Yes — no signup, no email required, no watermarks, no page limits, no daily quota, and no upsell for a paid tier. The tool runs entirely in your browser using free, open-source JavaScript libraries, so we have no server costs to recover. Your privacy IS the business model: we collect nothing because we have no use for it.

Is there a limit on file size or count?+

Practically, no — the only constraint is your device's available RAM, which is several gigabytes on any modern computer or phone. The tool has handled hundreds of pages and dozens of files in testing.
