pdfzus

The tool lets users upload several PDF files, rearrange their order with drag‑and‑drop, and merge them into a single document. All processing happens locally in the browser using WebAssembly, so no data is sent to a server and no registration or watermarks are required. After ordering, the combined PDF can be downloaded directly, optionally compressed to a target size.

It is aimed at individuals who need to assemble confidential or administrative PDFs—such as application materials, reports, or contracts—without exposing the files to cloud services. The interface offers a straightforward three‑step workflow: drop files, verify sequence, and save the merged result. Features also include page organization, splitting, signing, compression, and conversion between common formats, all performed client‑side under TLS protection and GDPR‑compliant safeguards.
