The hidden cost behind convenience
Search Google for 'image converter' or 'PDF compression' and you'll find countless free sites. But most urge you to upload files or require login for 'better' features. Are they really offering this out of pure goodwill?
The real reason they want your files on their servers
The moment you upload a file to a server, that data is no longer yours alone.
No matter how strong the security, no server is 100% safe from breach. The fact that your private or family photos are stored somewhere is always a cause for concern.

They analyze the photos and documents you upload and use that information for ad targeting.
Server storage risks
