Should you choose a PDF repair software or an online PDF repair tool?

PDF repair tools can be divided into two major categories: desktop PDF repair software and online PDF repair tools.

Desktop PDF repair tools, such as the Fixo Document Repair tool, offer more flexibility and security. Online PDF repair tools require no download and are easy to use but come with privacy concerns and the risk of virus infection.

Besides, in terms of pricing, online tools charge per document. In this regard, desktop software has the upper hand since it can fix as many PDFs as you want once activated.
