How to Adjust Image Colors and Lighting Online?

  1. After uploading, compare side by side in the preview: original on one side, adjusted result on the other — every change is easy to judge.
  2. For quick edits, tap a preset filter to apply it instantly — more than a dozen styles including Vivid, Vintage, Black & White, Warm and Cool tones.
  3. For precise control, fine-tune each of the nine sliders: brightness, contrast, exposure, hue, saturation, shadows, sharpen, temperature and tint.
  4. When satisfied, hit "Apply to All" to batch-apply the current settings to every uploaded image, then download one by one or as a ZIP package.

Frequently Asked Questions

Can I combine presets with manual adjustments?

Yes. A preset is simply a set of pre-tuned values that get reflected on the sliders when clicked — you can keep refining from that starting point until it looks exactly right.

What's the difference between temperature and tint?

Temperature shifts warmth: raising it goes yellow/warm, lowering it goes blue/cool. Tint fine-tunes between green and magenta, handy for fixing skin tones that lean green. Together they control the overall mood precisely.

Do all images share the same settings in batch mode?

Yes — "Apply to All" copies your current settings onto every image unchanged, perfect for bursts from the same scene or sets shot under identical lighting.

Is the adjustment lossy?

The live preview never touches your original file; final quality depends on the export format — PNG is completely lossless while JPEG follows the quality slider. Export important photos at high quality.

What happens if I push sharpen too far?

Over-sharpening creates white halos around edges and amplifies noise, making the image look harsh. Keep it subtle (especially for portraits): several gentle passes beat one extreme pull.

Are my images uploaded anywhere?

No. All adjustments render locally in your browser in real time — files never leave your device.
