Adjust Image is a free online tool on YouLoveTools that fixes the three things most often wrong with a photo: it is too dark, too flat, or its colours look washed out. Three simple sliders — brightness, contrast and saturation — update the preview live, so you can rescue phone photos, scans and screenshots without learning complicated editing software. Your image is never uploaded; every change happens in your own browser, on your own device.

Frequently Asked Questions
Q: What do the three sliders actually do?
A: Brightness makes the whole image lighter or darker. Contrast stretches the gap between dark and light areas. Saturation makes colours stronger or weaker — at 0% the image is grey.
Q: My photo looks worse the more I slide. What went wrong?
A: Big moves clip detail. Try small steps, in this order: brightness, then contrast, then saturation.
Q: Can I fix a blurry photo here?
A: No — these sliders fix light and colour, not focus. A blurry photo stays blurry.
It is also the fastest rescue for scans and screenshots that came out grey and lifeless — a touch of contrast alone often makes text look freshly printed. No layers, no menus, no learning curve.
Tip: If skin tones start looking orange, you have pushed saturation too far — pull it back until faces look human again.
