💡 Pro Tips
Subtle Tint: For a professional look, use a lower intensity (around 20-30%) to give a subtle, dreamy colorful vibe without overpowering the photo.
Direction Matters: Try aligning the gradient direction with light sources in your photo for a more natural-looking flare effect.
Contrast Boost: Adding a rainbow overlay can sometimes flatten the image. Increase the contrast slightly in Advanced Options to make the colors pop.
Black & White Base: Try applying the rainbow effect over a grayscale image for a dramatic, high-impact result.

Practical tool guide
Using Rainbow Effect Tool effectively
Add a colorful rainbow overlay to your photos. This page is designed to help you work with the result with a clear browser-based workflow rather than making you install a separate utility for a small task.
How to use it
Load an image, make one focused change at a time, compare the preview with the source, and export only after dimensions, format and quality look right.
Best used for
- web and social media assets
- quick format or size adjustments
- preparing images for documents and online forms
What to verify
Use it when you need a focused result without installing a separate desktop application. Repeated lossy exports can reduce image quality. Keep an untouched original when editing important photos, artwork or brand assets.
Expected: A result that matches the options you selected and can be checked against the original input. Avoid: Using the output immediately without checking a representative part of it first.
Why this workflow matters
Image workflows are usually a trade-off between visual quality, dimensions, format and file size. Rainbow Effect Tool is intended for a focused edit rather than a long creative workflow. Compare the preview with the original at normal viewing size, check text and edges for artifacts, and export once you are satisfied. Keeping the untouched source makes it easier to try different settings without accumulating quality loss.
