Frequently asked questions

How do I fix an over- or under-exposed photo?

Upload your image above and drag the exposure slider left to darken or right to brighten. The preview updates live, then click download to save it.

Is the exposure tool free?

Yes — completely free and unlimited. No signup, no account, no watermark, no daily limit.

What is EV (exposure value)?

EV is a photographic unit where each +1 stop doubles the light and each -1 stop halves it. The slider maps -100 to -2 EV and +100 to +2 EV, mimicking camera exposure compensation.

Are my files uploaded to a server?

No. The correction happens entirely in your browser on your device. Your image never leaves your computer, so it stays fully private.
