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.
Files are processed on your device — never uploaded, never stored, never seen by anyone.
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.
