Frequently Asked Questions
How do I adjust image brightness online?
Upload your image and use the brightness slider to increase or decrease the light level. Move right for brighter, left for darker. The preview updates in real-time so you can find the perfect setting.
What is the difference between brightness and contrast?
Brightness uniformly increases or decreases the light level of all pixels. Contrast adjusts the difference between the lightest and darkest parts, making lights lighter and darks darker (or vice versa).
Can I reset adjustments to the original?
Yes. Click the "Reset" button to restore both brightness and contrast to their default values (100%). You can also use the Clear button to remove the image entirely and start over.
Is my data safe?
Yes! All processing happens entirely in your browser using CSS Canvas filters. Your images are never uploaded to any server. No data is collected, stored, or transmitted.
What image formats are supported?
