Frequently Asked Questions
How do I brighten a dark photo?
Upload your image and drag the Brightness slider above 100%. The preview updates live, so you can dial in the exact look before downloading — all processing happens locally on your device.
What is the difference between brightness and contrast?
Brightness lightens or darkens the whole image evenly, while contrast increases the difference between the light and dark areas to make the photo look punchier. Saturation controls how vivid the colors are.
Will adjusting my photo upload it anywhere?
No. Every adjustment runs in your browser using the canvas API, so your photo never leaves your device and nothing is sent to a server.
