The challenge is to find a powerful and user-friendly tool that allows for efficient combining of multiple PDFs into a single document. It is important that the quality of the original files remains unrestricted, i.e., there should be no losses in terms of formatting or image quality. Another criterion is the ability to freely choose the order of the files and, if necessary, to make changes before the final merge. In addition, the software should be free to use, without the need for registration or installation, directly in the web browser. Due to privacy concerns, it is also of great importance that uploaded files are securely deleted after processing.
