Frequently asked questions
Can I blur only the background?
Yes. The AI Background Blur tool detects the subject and blurs only what is behind it.
Is blurring safe for hiding sensitive information?
Weak blur on text can sometimes be reversed. For sensitive data, crop it out or use a very strong blur.
Is it free?
Yes. Browser tools on PhotoTools are free, unlimited and work without an account.
Are my images uploaded to a server?
No. This tool runs entirely in your browser using WebAssembly. Your images never leave your device, and nothing is stored.
