→Frequently asked questions
- How to adjust color channels in an image?
- Select your file, then drag the red, green, and blue sliders to add or subtract from each channel independently.
- What does adjusting channels do to an image?
- It shifts color balance by independently adding or subtracting from each of the red, green, and blue channels.
- Is this like Photoshop's Channel Mixer?
- Similar — both adjust individual color channels. Photoshop's Channel Mixer remixes channels proportionally; this tool adds a fixed offset per channel, closer to a simple color balance shift.
- What file formats can I export?
- You can export as PNG, JPEG, WebP, TIFF, BMP, or HEIC.
- Is this tool free to use?
- Yes — completely free, no account needed. Your images are processed entirely in your browser and never uploaded to a server. Downloads have no watermarks.
