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.
