Brighten an image

Dial in the amount

Brightness is a simple multiplier — 1 is unchanged, 1.4 is a noticeable lift, 2 doubles it. Pair it with contrast in the convert step for a punchier result.

Keeps your format

The brightened 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 brighten an image?

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

Can I darken it instead?

Yes — set brightness below 1 (e.g. 0.7) in the convert step to darken an over-exposed photo.

Is it free and private?

Yes — no account needed, over an encrypted connection, and anonymous files are temporary.
