FAQ

Is Zight's image sharpener free?

Yes, completely free. No account or credit card is required.

Are my files uploaded anywhere?

No. This tool runs entirely in your browser — your files are processed on your own device and never uploaded to a server.

Can sharpening fix a very blurry photo?

It improves mild softness. Heavy blur destroys detail that no filter can recover.

Why does too much sharpening look bad?

Over-sharpening creates halos around edges. Start around 40% and adjust from there.
