이미지 brightness is one of the most impactful adjustments you can make to a photo. Underexposed 이미지 lose detail in shadows, while overexposed photos blow out highlights. Our brightness adjustment tool gives you precise control to correct exposure issues or create intentional lighting effects. Use the slider to increase brightness for dark indoor shots, reduce it for overexposed outdoor photos, or fine-tune the overall luminance to match your creative vision. The adjustment is applied uniformly across the 이미지 while preserving color relationships and tonal range. Works with all major formats including JPG, PNG, WebP, and HEIC. Process individual 이미지 or adjust brightness across an entire batch. All processing runs in your browser for speed and privacy.
