Frequently Asked Questions
- Is this image color adjustment tool free?
- Yes, 100% free. No account, no subscription, no limits on how many images you can process.
- Are my images uploaded to a server?
- No — everything runs in your browser using the Canvas API. Your image data is never sent to any server.
- What does the Exposure (Gamma) slider do?
- Gamma correction adjusts the overall luminosity curve of the image. Values below 1.0 darken midtones; values above 1.0 brighten them — similar to exposure compensation on a camera.
- How is this different from the Image Filters tool?
- Image Filters applies artistic presets (vintage, vivid, B&W, etc.). Image Color Adjust gives you precise numerical control over individual parameters — ideal for correction rather than creative effects.
- Does the tool work on mobile?
- Yes, it works on all modern browsers including mobile Safari and Chrome on iOS and Android. The before/after slider is touch-friendly.
