How it works

  1. Upload your outdoor photo

    Drop your landscape or outdoor photo into EditThisPic. JPG, PNG, WebP up to 7MB. Best results come from photos with visible sky and natural lighting. Cloudy or post-storm skies work especially well for realistic rainbow effects.

    Expect: Simple rainbow placement: 15-30 seconds. Complex scenes with multiple elements or specific positioning: may need 2-3 refinements for perfect placement.
  2. Describe the rainbow you want

    Type your instruction: 'add a natural-looking rainbow across the sky from left to right' or 'add a faint double rainbow in the upper sky.' Be specific about arc position, intensity (faint, vibrant, subtle), and placement. No marking needed—the AI understands sky context and natural rainbow physics. Include details like 'with sunlight breaking through clouds' for even more realism.

    Tip: Mention weather context like 'post-storm rainbow' or 'early morning rainbow' for AI to match lighting conditions naturally.

    Copy one of these to get started:

    Classic full arc rainbow add a natural-looking rainbow across the entire sky from left edge to right edge, vibrant colors, post-storm lighting
    Subtle single rainbow add a faint rainbow in the upper third of the sky, soft pastel colors, early morning light
    Double rainbow effect add a double rainbow with the main rainbow bright and vivid, secondary rainbow fainter above it, both arcing from left to right
    Partial rainbow arc add a partial rainbow visible only on the right side of the sky, fading into clouds on the left, medium intensity
    3 more prompts
    Low horizon rainbow add a low rainbow near the horizon with the arc barely visible, touching the ground at both ends, golden hour lighting
    Dramatic vivid rainbow add a highly saturated rainbow with extremely vibrant reds, oranges, yellows, greens, blues, purples arcing prominently across dark storm clouds
    Rainbow with sunbeams add a rainbow in the right side of the sky with sun rays breaking through clouds on the left, creating natural post-storm atmosphere
  3. Generate and review

    AI analyzes your sky, lighting conditions, and cloud formations to place a realistic rainbow. Check the arc shape, color intensity, and how it blends with existing weather conditions. Zoom in to verify the rainbow's edges fade naturally into the sky.

Mountain landscape rainbow

Added a full-arc rainbow to a mountain vista after storm clouds cleared. The rainbow naturally follows the sky's curve and fades at both endpoints.

Prompt: add a natural-looking rainbow across the entire sky from left edge to right edge, vibrant colors, post-storm lighting

Beach sunset with partial rainbow

Added a subtle partial rainbow on the horizon during golden hour. The rainbow coordinates perfectly with the warm sunset lighting.

Prompt: add a partial rainbow visible only on the right side of the sky, fading into clouds on the left, medium intensity, golden hour lighting

Quick answers

Do I need to mark the sky before adding a rainbow?

No! Just describe what you want: 'add a natural rainbow across the sky from left to right' or 'add a faint rainbow in the upper sky.' The AI understands sky context.

How do I make the rainbow look natural and not fake?

Use descriptive words about intensity and context. Instead of just 'add rainbow', try 'add a faint post-storm rainbow with soft colors' or 'add a subtle rainbow visible in the upper sky.' Mentioning weather context (post-storm, early morning, golden hour) helps AI match your photo's lighting. Lower intensity rainbows almost always look more natural than vivid ones.

What is the best free AI tool to add rainbows to photos?

EditThisPic's AI Rainbow Adder handles natural rainbow placement without complex masking or layers. Just describe the rainbow you want, and AI adds it in 15-30 seconds with realistic color gradients, natural arc curves, and proper sky blending. Free to try with no signup or watermark.

Can I add double rainbows or partial rainbows?

Yes! For double rainbows, describe both arcs: 'add a double rainbow with bright primary arc and fainter secondary rainbow above it.' For partial rainbows, specify visibility: 'add a partial rainbow visible only on the right side, fading into clouds.' The AI handles proper color order and intensity differences automatically.

Why does my rainbow look too bright compared to the rest of the photo?

The default is often maximum saturation. Add intensity descriptors to your prompt: 'faint', 'subtle', 'soft pastel colors', or 'low saturation rainbow.' You can also mention lighting conditions like 'matching overcast lighting' or 'complementing golden hour tones' to help AI adjust vibrancy to your scene.
