Common questions

Are my images uploaded?

No. Sharpening is rendered locally in your browser using File, Canvas, Blob, and object URL APIs.

Can this fix severe blur?

No. This is a simple sharpening filter for mild softness. Severe blur usually needs AI enhancement or a sharper source image.

Need stronger enhancement?

Use AI Enhance when you need blur recovery, upscaling, denoising, and more natural detail restoration.
