Does denoising make photos blurry?

It costs some detail, and every denoising algorithm has this problem — software cannot reliably tell noise from very fine texture. Do not max the strength; stop when the noise is acceptable.

Do I need an account? Is it paid?

Neither. Free, no sign-up, no usage cap, and no watermark.

Is my photo uploaded?

No. Denoising runs entirely in your own browser — we never receive the file.

Should I denoise or sharpen first?

Denoise first, sharpen after. The other way round, sharpening amplifies the noise as well, so you then need a heavier denoise pass and lose more detail.

Drop in a noisy photo, drag the strength slider, and the grain falls away.

There are two kinds of noise: luminance noise gives the picture a grainy texture, colour noise is those stray red and green speckles. Keeping them on separate controls is what makes it manageable — colour noise can be crushed hard with almost no detail loss, while pushing luminance noise too far makes the image look waxy. Everything is computed in your own browser and the photo is never uploaded. Some detail loss is unavoidable: the algorithm cannot tell fine texture from noise.

Key features

Two noise types apart

Luminance and colour noise each get their own slider — they do not interfere.

Detail preservation

A separate control that holds on to texture while the noise comes down.

How to use

1
Add a photo

Drag it into the box, or press Ctrl+V to paste.
2
Kill colour noise first

Clear those red and green speckles — this step costs almost no detail.
3
Then luminance noise

Raise it gradually and back off as soon as the image starts looking waxy.

Download

Save it, or follow with sharpening to bring the edges back.
