Is it private and safe to merge PDF files online?

Updated July 2026

Yes. When you merge PDF files in Arthize, the file is processed inside your private workspace and deleted after the job — never sold or used to train models. A proper merge is lossless because it copies existing page objects instead of re-rendering them.
