Image brightness adjustment controls the overall lightness or darkness of your photos. Increase brightness to lighten underexposed images taken in low light conditions, or decrease brightness to fix overexposed photos that appear washed out. This online brightness editor processes JPG, PNG, and WebP images directly in your browser, preserving image quality while fine-tuning exposure levels for perfect lighting.
Upload your photo to start adjusting brightness instantly. Drag the brightness slider right to increase lightness for dark images, or slide left to decrease brightness for overly bright photos. The live preview updates in real-time, showing exactly how your brightness adjustments affect the image. Download your corrected photo as high-quality PNG for lossless output, or choose JPEG/WebP for smaller file sizes ideal for web sharing and social media.
Increase brightness for underexposed photos from indoor events without flash, dark smartphone selfies, or product photos shot in poor lighting. The brightness boost reveals hidden details in shadows and makes colors more vibrant. Decrease brightness for overexposed beach vacation shots, outdoor photos taken in harsh sunlight, or images with blown-out highlights. Reducing brightness creates balanced exposure and prevents washed-out appearance in overly bright areas.
Use brightness adjustment for underexposed photos from indoor events, dark basement shots, nighttime photography without proper lighting, or smartphone photos taken without flash. Increase brightness to make faces visible in group photos shot indoors. Decrease brightness for washed-out beach photos, overexposed landscape shots, product photography with excessive lighting, or to create moody, dramatic effects for Instagram posts and creative projects.
All brightness adjustments happen directly in your browser using HTML5 canvas technology. Your images never leave your device, ensuring complete privacy and security. Export adjusted images up to 4096x4096 resolution. PNG format maintains lossless quality perfect for professional photography and print work. WebP reduces file size by 30-50% compared to JPEG while preserving visual quality - ideal for website optimization, email sharing, and faster social media uploads.
