Overview
ImageOnline Color Grading tunes the color and tone of a photo with five sliders and nothing else. Highlights, shadows and midtones set the tone. Temperature and tint pull out a color cast, warm to cool or green to magenta. It has no AI, presets or auto looks. Every slider works on the whole photo, so there are no masks, curves or per-color control.
It runs in the browser only, and the vendor states the photo is processed on your device and never uploaded. It is free, needs no account and adds no watermark. You export the result as PNG, JPEG or WebP.

When to use
Use ImageOnline Color Grading if:
- You want to warm up or cool down a photo in a few seconds with a temperature slider.
- You want to recover blown-out highlights or lift dark shadows without opening a full editor.
- You care about privacy and want the photo to stay on your device instead of being uploaded.
- You want a free tool with no account or watermark on the result.
- You need the output as a PNG, JPEG or WebP file.
When NOT to use
Skip ImageOnline Color Grading if any of these describe you:
- You want one-click AI looks or auto color correction, since this tool is manual sliders only. Try an AI color grader instead.
- You need to grade only part of the image, because every slider here affects the whole photo.
- You need curves, per-color (HSL) control or film-style LUTs, which this tool does not have.
- You want to save a look and apply it to a whole shoot, since it works on one image at a time.
Frequently asked questions
Yes. The color grading tool is free, needs no account and adds no watermark to your photo. It is one of many free tools in the imageonline.io suite. The page carries ads.
The vendor states that all processing happens in your browser and that images are never uploaded to a server. That means the photo stays on your device while you edit it.
No. It is manual only. You move the five sliders yourself. If you want a one-click automatic look, you need a different tool.
It loads common image files and lets you export the result as PNG, JPEG or WebP. PNG keeps exact colors, JPEG makes a smaller file, and WebP is smaller still.
No. Every slider changes the whole image. There are no masks, brushes or selections, so it cannot grade only the sky or only a face.
No. The page sets no limit on file size or resolution, and the finished image downloads at the same size as the one you loaded.
