In sintesi (BLUF): The tool brightens dark and underexposed photos right in your browser: it lifts shadows, keeps highlights and reduces the noise that grows together with brightness. Your photo is never uploaded, no weights are downloaded and no tokens are charged — the tool is free.
Drop a photo into the window or choose a file on your device. The tool estimates the lighting of every area and lifts dark regions more than bright ones, so skies and lamps do not blow out while faces and details in shadow become visible.
Leave the strength on Auto or set it by hand, and tune noise reduction and color saturation. Compare the result with the original on the page and download it as a lossless PNG.
When shadows are lifted, sensor noise is amplified with them. The tool smooths noise where brightness was raised the most and keeps bright details sharp. If you want to keep the grain, just lower the noise reduction slider.
Everything runs on your device: the photo is not sent to a server, no sign-up is required and no tokens are charged. Your original file is not changed — you download a separate result.
Yes. It runs in your browser, needs no login and spends no tokens.
