Merge multiple PDFs into one — fast and privately

Combine any number of PDFs into a single, well‑ordered document. Drag PDFs into the queue, reorder them with the mouse, optionally remove or rotate pages, and export a clean merged file. Everything runs locally in your browser using pdf‑lib, so confidential contracts, expense reports and medical records stay private.

Merging PDFs is one of the most common office tasks, but most online tools force you to upload your sensitive documents to an unknown server. With ToolsGuru, the merge happens on your own machine — there's no upload step, no waiting on a server queue, and no copy of your file left behind.

Beyond simple end‑to‑end concatenation, you can rearrange pages between documents, drop pages you don't want, and rotate misaligned scans. The result is a polished, professional merged PDF with no quality loss and no watermarks.
