FAQ

Do you upload my images?+

No. Blur and sharpen run entirely in your browser. Your files never leave your device.

What's the difference between blur and sharpen?+

Blur softens the image (useful for backgrounds). Sharpen increases local contrast to make edges look crisper.

Can heavy sharpen look unnatural?+

Yes — start around 30–50% and increase carefully. Over-sharpening adds halos.

Is PrivyTool free?+

Yes. Basic image tools are free with no account required.
