The privacy spectrum of online photo tools

Online photo tools fall on a spectrum from fully private to deeply concerning:

LevelHow it worksPrivacy risk
Client-side (best)Processing happens in your browserMinimal โ€” photos never leave your device

  • Requiring account creation for basic features.
  • Terms of service granting the tool rights to your uploaded content.
  • No mention of data retention policies.
  • Servers in countries with weak data protection laws.

How to stay safe

  • Use client-side tools like PhotoResizer.us that process images in your browser.
  • Read the GDPR compliance guide before using any tool.
