Osvetljavanje slike

Lightening an image selectively enhances the lighter areas while preserving shadows and contrast. This creates a more natural look that maintains the image's mood and dimension. In contrast, increasing brightness uniformly affects all pixels, which can wash out details and flatten the image. Our lightening tool is designed to give you more control over the tonal range of your image.

There are many reasons to lighten images: to recover details hidden in shadows, enhance underexposed photos, create airy aesthetics for fashion or product photography, improve visibility in interior photos, prepare images for social media, or achieve specific creative effects. Lightening can help reveal important details while maintaining the overall mood of your image.

The "Preserve Colors" option maintains the natural color balance of your image while increasing lightness. It works by converting the image to HSL (Hue, Saturation, Lightness) color space, adjusting only the lightness component, and then converting back to RGB. This prevents color shifting or washing out that can occur with simple RGB adjustments, resulting in more natural-looking images.

Extreme lightness adjustments can potentially reduce image quality by revealing noise, losing detail in highlights, or causing color shifts. However, our tool is designed to minimize these issues, especially when using the "Preserve Colors" option. For best results, use moderate adjustments (20-40%) and check the preview carefully.

No. This tool processes your image entirely within your browser. Your image is never uploaded to our servers, ensuring complete privacy and faster processing. This also means you can use the tool offline once the page has loaded.

Our tool supports all common image formats including PNG, JPEG, WebP, GIF, and BMP. You can also download your lightened image in PNG, JPEG, or WebP formats, regardless of the original format.

For the best results when lightening an image: 1) Start with a moderate lightness adjustment (20-40%), 2) Enable "Preserve Colors" to maintain natural color balance, 3) Use the comparison feature (press and hold) to check against the original, 4) For creative effects, try higher lightness values (60-80%), 5) If details appear washed out, reduce the lightness slightly.
