Frequently Asked Questions

What color adjustments are available?

You can adjust brightness, contrast, saturation, hue rotation, color temperature (warm/cool), and exposure.

Can I undo my changes?

Yes! Use the 'Reset All' button to revert all sliders to their default values. Your original image is never modified.

Is there a live preview?

Yes, all adjustments are previewed in real time on the image before you apply and download.

What image formats are supported?

All common formats are supported: JPEG, PNG, WebP, and more. Output preserves your original format.

Are my images uploaded to a server?

No. All adjustments are processed entirely in your browser. Your images never leave your device.

Can I adjust multiple images at once?

Currently the tool adjusts one image at a time. Apply your desired settings, download the result, then upload the next image.

Does this work on my phone?

Yes. The color adjustment tool works on any device with a modern browser. All sliders are touch-friendly for mobile use.

What is the difference between brightness and exposure?

Brightness uniformly lightens or darkens the image. Exposure simulates camera exposure changes, affecting highlights and shadows differently for more natural results.

Can I save my adjustment settings as a preset?

Currently each adjustment is made manually per image. Note your slider values if you want to replicate the same look across multiple images.

What does the hue slider do?

The hue slider rotates all colors around the color wheel. Small adjustments can shift color tones (e.g., making greens more teal). Large rotations produce dramatic color-shift effects.

Can I adjust just part of an image?

The adjustments apply to the entire image uniformly. For selective adjustments, use the crop tool to isolate a region, adjust it, then composite the results in an external editor.

How does temperature adjustment work?

Temperature shifts the color balance between warm (orange/yellow tones) and cool (blue tones). Moving toward warm corrects cold indoor lighting. Moving toward cool balances overly warm sunset or tungsten lighting.

Tips & Best Practices

Start with exposure and brightness, then fine-tune contrast and saturation for natural-looking results

Use the temperature slider to fix white balance — shift warm for indoor fluorescent, cool for golden hour overcorrection

Subtle adjustments usually look more professional — avoid maxing out any single slider
