Merge PDF without a watermark

Combine PDFs into one file with nothing added — no logo, no "merged with [tool]" stamp, no upsell to a paid plan to remove it. There's no paid plan; the output is just your pages, combined.

Why some free PDF mergers add a watermark (and this one doesn't)

A common pattern with free online tools is to let you merge for free, but stamp the result with the tool's own logo or a "created with [name]" footer — and charge you to remove it. It's a reasonable business model for a company running servers to process your files, but it means the "free" version isn't really the finished product you wanted.

This tool works differently because of how it's built: there's no server processing your file at all. Merging happens with JavaScript running in your own browser (using the pdf-lib library), copying pages directly from your source files into a new PDF. There's no server-side step where a company could insert a branding stamp even if it wanted to, and no paid tier to upsell you into, so the output is exactly what you'd expect — just your pages, in order, nothing added.

Will this add a watermark or logo to my merged PDF?
No — never. The merged file contains exactly the pages from your source files, copied as-is, with nothing added or stamped anywhere.
Why do some other free PDF mergers add a watermark?
It's a common upsell tactic — the free tier works but brands the output, and removing the mark requires a paid plan. Since this tool has no paid tier, there's nothing to upsell to and no reason to brand your file.
Is there a page or file count limit?
No artificial limit — it's bound only by your device's memory, so very large batches may be slower.
Are my files uploaded anywhere?
No — merging happens entirely in your browser using JavaScript, which is what makes it safe: your PDFs stay with you and are never sent anywhere. See how it works.
