The download comes back in the format you started with, at the same pixel size.

Grayscale an image without losing detail

Grayscale an image here and the pixel dimensions stay the same. Nothing gets resized, so a 4000 pixel wide photo is saved 4000 pixels wide. JPEG and WebP files are re-encoded when saved, so file size and fine compression detail can change. PNG is encoded losslessly.

What grayscale actually does to a photo

Every pixel in a color photo has red, green and blue values. The converter calculates grayscale from roughly 21 percent red, 72 percent green and 7 percent blue. These Rec. 709 weights approximate perceived brightness more closely than averaging the three channels equally.

Color and grayscale versions of the same photograph. The converter uses Rec. 709 channel weights instead of averaging red, green and blue equally.

The Strength slider

At 100 the color is gone. Pull Strength back and some of it stays, which suits a portrait: skin keeps a little warmth. Set it wherever it looks right before you save.

Going the other way, color from black and white

If you are holding an old black and white print, the useful direction is the opposite one. PicFix uses an AI model to add color to black and white photographs. The model runs on PicFix servers, and you see the finished result before payment.
