Possible disadvantages

• Cost

• Reliance on Internet
  Certain features and integrations may require a stable internet connection, which can be inconvenient in areas with limited connectivity.

• Convenient PDF access
  Tools branded as PDFStart generally aim to put common PDF tasks such as converting, editing, merging or viewing in one place, which can save time compared with searching for separate tools. I could not verify the exact feature set on pdfstart.com, so check the site for specifics.

  Online PDF utilities of this kind usually have a minimal interface where you upload a file and pick an action, so non-technical users can get started quickly. Confirm this by trying the tool on a non-sensitive document.
• No heavy software install (if web-based)
  If the service runs in the browser, it works across operating systems without installing desktop software. This is useful for occasional use or on shared and locked-down computers.
• Possible free tier for basic tasks
  Many comparable services let users try basic functions for free before asking them to pay. This lets you test output quality before committing, but check the site for the actual pricing and limits.
