Possible disadvantages

  Since files are uploaded to the cloud for conversion, there could be privacy concerns regarding sensitive or confidential data.
• Limited Free Features
  Some advanced features and higher quality conversions are only available through a paid subscription, which can be a drawback for users seeking a free solution.
• Internet Dependency
  Being a web-based service, Convertio requires a stable internet connection for file uploads, conversions, and downloads, potentially limiting its usability in offline scenarios.
• Waiting Times for Free Users
  Free users might experience longer waiting times due to lower priority in the conversion queue compared to premium users.

Possible disadvantages

• Internet Dependency
  As a web-based tool, it requires a stable internet connection to function, making it unusable in offline scenarios or areas with poor connectivity.
• Privacy and Security Concerns
  Uploading sensitive or confidential documents to an online platform raises potential privacy risks, as files are processed on external servers.
• File Size Limitations
  Free versions of online PDF tools often impose restrictions on file size or the number of operations, which can be limiting for users with large documents.
• Potential Advertisements
  Free web-based tools frequently include ads or upsell prompts for premium features, which can disrupt the user experience.
• Limited Advanced Features
  Compared to dedicated desktop PDF software, PdfToolStack may lack more sophisticated editing capabilities needed by professional or power users.
