Increase image contrast

From flat to punchy

Contrast is a multiplier — 1 is unchanged, 1.4 deepens shadows and brightens highlights, lower than 1 flattens it. Combine with brightness for the look you want.

Keeps your format

The adjusted image is saved back in its own format, or pick another in the convert step. Anonymous uploads are temporary and encrypted in transit.

Frequently asked questions

How do I increase contrast?

Upload your photo — it's pre-set to a 1.4× contrast boost. Adjust the amount in the convert step and download.

Can I reduce contrast too?

Yes — set contrast below 1 (e.g. 0.8) to soften a harsh, over-contrasty image.

Is it free and private?

Yes — no account, encrypted in transit, and anonymous files are temporary.
