Best Practices
Always strip EXIF metadata before sharing photos online — it can contain GPS coordinates
Blur faces of people who have not given consent to be photographed
Blur sensitive information like license plates, addresses, and personal documents
Use strong blur or pixelation — light blur can sometimes be reversed
Check the protected image carefully — ensure no identifying information remains
Educate yourself about what metadata your phone camera embeds in every photo
Pro Tips for Better Results
Use Gaussian blur with a radius of at least 20px for effective face blurring
Strip metadata from all images before uploading to social media platforms
For maximum privacy, combine metadata removal with face blurring
When sharing screenshots, blur any personal information including usernames and emails
Common Mistakes to Avoid
Forgetting that social media platforms may re-add their own metadata after upload

Only removing EXIF but forgetting about visual information in the photo
Not checking the protected image at full size before sharing
Trusting cloud-based privacy tools with sensitive photos — always use browser-based tools
