AI Inpainting: How to Edit and Fix Any Part of an Image (2026)

You've generated an almost-perfect image — great composition, beautiful colors, exactly the mood you wanted — but one thing is off. Maybe the face looks slightly wrong, there's an extra object in the background, or you want to swap a plain sky for a dramatic sunset. With traditional editing you'd need Photoshop skills and an hour of careful work. With AI inpainting, you paint over the problem area, type what should go there, and the AI fills it in seamlessly — in seconds.

This guide covers everything you need to know about AI inpainting using PixelMind AI's built-in inpaint tool: what it is, when to use it, step-by-step instructions, and real-world recipes for common fixes. Free daily credits included — no extra software needed. If you're new, start with how to write AI image prompts and the free AI generator guide.

Inpainting turns "almost perfect" into "exactly right" — it's the difference between starting over and making a quick, surgical fix.

What is AI inpainting?

Inpainting is an AI editing technique where you mask (paint over) a specific region of an image and provide a text prompt describing what should appear in that area. The AI model then regenerates only the masked region, blending it seamlessly with the untouched surroundings. The rest of the image stays pixel-perfect — colors, lighting, and perspective all match.

Think of it like a magical eraser-and-brush combo: erase the part you don't like, tell the AI what to paint there instead, and it handles the blending, shadows, and style matching automatically.

What you can do with inpainting

• Fix faces and hands — AI generators sometimes produce distorted features. Mask the face or hand, re-describe it, and get a natural result.
• Remove unwanted objects — an extra person in the background, a distracting sign, a floating artifact. Mask it and prompt "clean background" or describe what should be there instead.
• Swap backgrounds — keep your subject but replace the setting. Mask everything behind the subject and describe a new environment.
• Change clothing or accessories — mask a shirt and prompt "elegant black tuxedo" or mask glasses and prompt "vintage round sunglasses."
• Add elements — mask an empty area and prompt something new: a cat on the windowsill, a sword in the character's hand, a logo on the wall.
• Fix style inconsistencies — if one part of the image looks different from the rest, mask it and regenerate with the same style prompt to unify the look.

Step-by-step: how to inpaint in PixelMind

1. Generate or open your base image

Start with an image that's close to what you want. It can be one you just generated, an earlier creation from your gallery, or an uploaded image. The better the base, the less inpainting you'll need.

2. Open the inpaint tool

Click on the image to open the viewer, then select the Inpaint tool from the editing toolbar. This switches the viewer to mask-painting mode.

3. Paint your mask

Use the brush to paint over the area you want to change. The masked region will be highlighted (typically in a semi-transparent color). Tips for good masks:

• Cover the entire area you want changed — don't leave gaps inside the mask.
• Include a small margin around the target. This gives the AI room to blend edges smoothly.
• Don't mask too much. The smaller the mask relative to the image, the more context the AI has to match lighting, style, and perspective. Masking 80% of the image is basically regenerating from scratch.
• For precision work (eyes, jewelry, small details), zoom in before masking.

4. Write your inpaint prompt

Describe what should appear in the masked area. Be specific about the replacement, not about what you're removing. Good vs. bad examples:

• ✅ "warm sunset sky with orange and purple clouds" — tells the AI exactly what to paint.
• ❌ "remove the ugly gray sky" — the AI needs to know what to put there, not just what to take away.
• ✅ "natural relaxed hand resting on the table, five fingers" — specific, clear.
• ❌ "fix the hand" — too vague; fix how?

5. Generate and compare

Hit generate. The AI fills in the masked area while keeping everything else intact. Compare the result — if it's not quite right, adjust your mask or prompt and try again. Each attempt costs a small number of credits, so you can iterate quickly.

Real-world inpainting recipes

Fix a distorted face

Mask the face, leaving the hairline and neck unmasked. Prompt: "beautiful natural face, symmetrical features, soft expression, same lighting as surroundings". For anime style, add "anime face, large expressive eyes, clean linework."

Remove a background object

Mask the object plus a few pixels around it. Prompt with a description of the background that should continue behind it: "continuation of the brick wall, same color and texture, natural weathering". The simpler and more uniform the background, the cleaner the removal.

Swap a background completely

Mask everything behind the subject. Write a detailed environment prompt: "futuristic neon cityscape at night, towering buildings, holographic signs, atmospheric haze, cyberpunk". The AI will match the lighting on the subject to the new background. This works especially well with the cyberpunk and sci-fi styles.

Add an element to an empty area

Mask the area where you want the new element. Be descriptive: "fluffy orange tabby cat sitting on the windowsill, looking outside, natural soft light". The key is matching the perspective and lighting of the existing scene.

Inpainting tips for better results

1. Match the style. If your image is watercolor, include "watercolor style" in your inpaint prompt so the filled area matches the rest.
2. Iterate in small steps. Fix one thing at a time rather than masking multiple unrelated areas. Each fix is more precise when the AI only has one job.
3. Use inpainting before upscaling. Fix issues at the base resolution, then upscale to 4K as the final step. It's faster, uses fewer credits, and produces cleaner results.
4. Describe lighting. If the masked area is in shadow, say so. If there's a warm light source from the left, mention it. Lighting mismatches are the most common giveaway of a bad edit.
5. Regenerate, don't re-mask, if the result is close. If the fill is 90% right, just hit generate again with the same mask and prompt — the model may nail it on the next attempt. You don't have to re-draw the mask each time.

Inpainting vs. other editing tools

PixelMind AI includes several editing tools. Here's when to use each:

• Inpainting — change or fix a specific region of the image (this guide).
• Outpainting — expand the canvas beyond its edges to add more scene around the subject.
• Upscaling — increase the resolution to 4K without changing the content. See the upscaling guide.
• Regeneration — start fresh with a new prompt if the image is fundamentally not what you want.

The ideal workflow: generate → inpaint fixes → outpaint if needed → upscale → download. Each tool does one thing well, and they stack in that order. Read 30 AI art prompt ideas for inspiration on what to generate and edit.
