About Merge PDF
Merge PDF combines two or more PDF documents into a single file in the order you choose. It's useful for assembling scanned receipts, stitching together report chapters, or bundling signed contracts before sending. Because everything runs locally, even confidential documents stay on your machine.

FAQ
How many PDFs can I merge at once?
There's no hard limit - merging happens in your browser, so the practical cap depends on your device's memory. Most users can comfortably merge 50+ documents totalling several hundred megabytes.
Will merging PDFs reduce quality?
No. Pages are copied byte-for-byte from the source PDFs, so text stays selectable and images keep their original resolution. Nothing is re-rendered or recompressed.
Are bookmarks and form fields preserved?
Page content, fonts, and form fields carry over. Some advanced features (top-level bookmarks, per-document JavaScript) may be flattened during the merge.
Is Merge PDF free?
Yes. Every tool on docsntools is 100% free with no signup, no watermarks, and no upload limits.
Are my files uploaded to a server?
No. All processing happens entirely in your browser. Your files never leave your device.
Does it work on mobile?
Yes - every tool is responsive and works in modern mobile browsers (Chrome, Safari, Firefox).
