How it works

Upload your photo

Drop your image into EditThisPic. Works best with outdoor photos that have a clear sky visible. JPG, PNG, WebP up to 7MB. Photos with buildings, landscapes, or people work great.

Expect: Simple clear skies: 15-20 seconds with natural blending. Complex scenes with trees or buildings: may need one refinement for perfect edge blending.
Describe the sky you want

Type your instruction: 'replace sky with golden hour sunset' or 'change sky to deep blue with white clouds.' Be specific about colors, time of day, and cloud type. No selection needed—the AI automatically detects where the sky is and preserves everything else.

Tip: Include lighting direction for realistic results: 'sunset with warm orange light from the right' helps the AI match the scene's lighting.

Generate and review

Click Generate and watch the AI replace your sky. Check the horizon line at full zoom to verify smooth blending. The AI automatically adjusts foreground lighting to match your new sky.
Refine edges if needed

If the horizon line needs adjustment or tree branches aren't perfect, tap markers on those specific areas and regenerate. Most sky replacements work perfectly without markers.

Tip: Markers are for precision refinement around complex edges like tree branches or building details. Simple horizons rarely need them.

If something looks off

AI changed the wrong area or affected buildings/trees

Why: Complex edges like tree branches or intricate architecture can be ambiguous for the AI to distinguish from sky.

Try:

Tap markers on the specific areas where the boundary should be preserved (like around tree branches), then regenerate with the same prompt

Try This →

Tip: Markers tell the AI 'preserve detail HERE.' Use them when you have complex silhouettes against the sky.

New sky doesn't match the scene lighting

Why: The original photo has directional lighting that doesn't match your requested sky (e.g., morning light with a sunset sky).

Try: Add lighting direction to your prompt: 'sunset with warm light from the left' or 'overcast with soft diffused light'

Try This →

Tip: Match your sky's time of day to the existing shadows. Morning light = sunrise, harsh shadows = midday, long shadows = sunset.

Horizon line looks cut-off or unnatural

Why: The AI had difficulty detecting the exact boundary between sky and foreground in your specific photo.

Try: Tap a few markers along the horizon line where you want the transition, then regenerate

Try This →

Tip: Photos with gradual horizons (like distant mountains fading into haze) may need marker guidance.

Colors look oversaturated or unrealistic

Why: Your prompt used very vivid descriptors that pushed the AI toward extreme color saturation.

Try: Use softer descriptors: instead of 'bright vivid orange', try 'warm golden orange' or 'soft sunset tones'

Try This →

Tip: Words like 'dramatic' and 'vibrant' increase saturation. Use 'soft', 'natural', or 'subtle' for realistic results.

Sky looks pasted on instead of blended

Why: The original photo had very different lighting or color temperature than the new sky.

Try:

Add 'with natural blending and matching foreground lighting' to your prompt, or try a sky that better matches the original scene's mood

Try This →

Tip: Extreme changes (night sky on a bright sunny photo) require more adjustment. Start with similar lighting conditions.

Clouds are too detailed or look artificial

Why: The AI interpreted your prompt as needing very defined cloud structures.

Try:

Simplify your cloud description: use 'wispy clouds' or 'scattered clouds' instead of specific cloud types like 'cumulonimbus'

Try This →

Tip: General descriptions like 'fluffy white clouds' work better than meteorological terms.

Quick answers

Do I need to mark the sky before describing?

No! Just describe what sky you want: 'replace sky with sunset' or 'change to blue sky with clouds.' The AI automatically detects where the sky is. Only use markers when you need precision around complex edges like tree branches or intricate architecture.

How do I replace the sky in a photo for free?

Upload your photo to EditThisPic, type what sky you want (like 'replace sky with dramatic sunset'), and click Generate. The AI handles sky detection and blending automatically. No Photoshop or manual masking required. Free to try with no signup.

Will the new sky look realistic or obviously edited?

The AI automatically blends the new sky with your horizon and adjusts foreground lighting to match. When you specify lighting that matches your scene (e.g., 'sunset with warm light from the right'), results look completely natural. The key is matching the sky's time of day to your photo's existing shadows and light direction.

Can I replace the sky in photos with buildings or trees?

Yes! The AI detects complex edges like building outlines, tree branches, and mountain silhouettes. For intricate details like fine branches or power lines, you may need to tap a few markers along those edges for perfect results, but most architectural and landscape photos work on the first try.

What is the best free AI tool for sky replacement?

EditThisPic offers free AI-powered sky replacement with no signup, no watermark, and no download required. Unlike traditional sky replacement tools that require manual masking, EditThisPic understands natural language prompts and handles detection and blending automatically.
