Adjust image brightness online free. Live preview sliders. Browser-based.
Indoor product shoots under tube lights often come out underexposed; flash can wash out packaging colors. Image Brightness exposes a −100 to +100 slider so you can correct exposure before listing without waiting for a studio retoucher. Everything runs in the browser — helpful for Indian sellers editing on the same laptop they use for Seller Central. Pair with contrast and compressor tools when the corrected file is still too heavy to upload.

Image Brightness is a free browser-based adjustment tool. Move one slider to lighten or darken an image, preview live, and download. It is meant for quick exposure fixes on catalog and social images, not for professional color grading suites. No signup is required.
Raise brightness for slightly dark phone photos of clear products. If shadow detail is pure black or colors clip, reshoot with better lighting (ring light + white backdrop).
Yes. Free, no watermark, no account. There is no trial wall, daily limit for ordinary catalog prep, or watermark stamped onto the download. If you are preparing Meesho or Amazon India listings, you can process photos one after another in the same browser tab and keep your master originals on disk. We keep the tool free so sellers without a Photoshop subscription can still meet platform image requirements.
Processing is designed to happen locally in your browser. We do not require you to upload photos to an account gallery.
