How to Edit AI Anime Art With PixAI: Different Ways to Fix and Improve Your Images
Getting a good AI-generated anime image is often only the beginning. You may have a strong character and composition, but still want to fix a hand, change an outfit, expand the background, or adjust the lighting before calling the image finished.
That’s usually a good time to edit AI anime art instead of starting over. Rather than changing everything to fix one problem, you can preserve the parts that already work and make targeted changes to the artwork.
PixAI brings several AI anime art editing approaches together, from inpainting and image expansion to reference-based editing, Img2Img, and upscaling.
We’ll look at what each method is good for and how you can combine them to take an AI anime image from a promising first generation to a more polished final result.
Start with the right image to edit
The best starting point is usually an image that’s already strong in the areas you want to preserve. Look for a good overall composition, a clear character silhouette, and a style you want to carry into the finished artwork.
Before editing, decide what actually needs to change. A small defect may call for inpainting, while a different composition or broader visual transformation may be better suited to another editing method.
It’s also worth keeping the original generation and its available settings, including the model, prompt, and seed. That gives you useful context if you want to recreate a variation or return to an earlier version later.
Fix specific problems with inpainting
When your overall image is good but has a specific issue, you can use inpainting to correct it.
What is inpainting?
Inpainting is a targeted editing method that lets you change part of an existing image without rebuilding the entire composition. You paint a mask over the area you want to replace, then give the model instructions for what should appear there. PixAI regenerates the masked region while using the surrounding artwork as context.
This makes inpainting particularly useful for AI anime art because many problems are localized. A character may have a well-rendered face, outfit, pose, and background while one hand, eye, accessory, or section of clothing needs work. Rather than risking those successful elements with a new generation, you can isolate the problem and work on that area.
Fixing hands, faces, and small details
When you have small anatomical or rendering problems, you can use inpainting to fix them.
For example, if the character’s hand has malformed fingers, mask just the hand and use a focused prompt such as:
detailed anime hand, five fingers, natural pose, clean line art
If you want to change the character’s eye color, keep the mask tight around the eyes and describe the new color and appearance.
Something like:
emerald green eyes, detailed green irises, natural anime expression
The same approach works for accessories, clothing details, and small background elements.
If the first result changes more of the image than you intended, make the mask smaller or refine the prompt to focus the edit more precisely.
When you want a more substantial correction, give the model a larger masked area and a more descriptive prompt.
Changing part of the character
Besides repairing an error, you can also use inpainting to make deliberate changes to a character. Mask the specific area you want to alter and describe the replacement in the prompt.
For example, you could mask the character’s hair accessory and use:
red ribbon hair ornament, detailed anime accessory
Or mask part of the outfit and ask for:
dark green winter coat, gold buttons, anime clothing
Keep the mask focused on the area you’re changing, while including enough surrounding context for the new element to blend naturally with the existing artwork.
This approach works well when you want to add accessories, change clothing details, or remove unwanted elements while keeping the rest of the character intact.
Change the image with prompts
Prompt-based editing is useful when the change affects a larger part of the artwork than a small masked area. Instead of correcting a single detail, you can use a prompt to give the image a new direction while keeping the existing artwork as the visual starting point.
Changing the character or outfit
Besides repairing an error, you can use prompt-based editing to make broader changes to a character. For example, you might keep the character’s face and pose while changing their clothing, hairstyle, or accessories.
PixAI’s Reference Pro model lets you use the original artwork as a visual reference and describe the change in natural language. You can add your image as a reference and write something like:
Keep the character’s face, hairstyle, and pose, but change the school uniform to a long winter coat with a scarf.
This way, you won’t have to rebuild the entire image using a new prompt, and you’ll also maintain character consistency. The approach can also be useful when creating different versions of the same character for a story, character sheet, or series of illustrations.
Changing the setting and atmosphere
Besides changing the character, you can use prompt-based editing to change the environment or overall mood of an image. This can be useful when the character already works, but the scene needs a different time of day, weather, or lighting.
For example, you could turn a bright daytime scene into a sunset setting with an instruction like:
Keep the character and composition unchanged, but change the scene to golden hour with warm sunset light, soft shadows, and an orange-pink sky.
You can make similar changes to weather, background details, or lighting. For broader changes like these, review the entire image afterward because altering the environment can also affect how the character and surrounding elements are rendered.
Expand the composition with outpainting
Sometimes the image itself is good, but the canvas is too tight for what you want to create.
Outpainting lets you extend the artwork beyond its original edges, giving the model room to generate more of the surrounding scene.
This can be especially useful when you want to turn a character portrait into a wider illustration or prepare an image for a different aspect ratio. In PixAI, you can expand the canvas and use a prompt to guide what should appear in the newly created areas.
For example, a square character portrait could be expanded toward a 16:9 composition with a prompt such as:
traditional Japanese village street, wooden houses, stone path, distant mountains, evening sky, warm lantern light
The original artwork acts as a visual starting point, and you can then extend the environment.
Transform an image with image-to-image generation
Image-to-image generation is useful when you want to edit AI anime art to change the overall appearance of an existing artwork rather than one specific area. You provide the original image as a starting point, then use a prompt to guide a new version while controlling how closely the result follows the source.
The main control to understand is denoising strength. A lower value keeps more of the original composition, character, and details, while a higher value gives the model more freedom to reinterpret the image.
For example, a setting around 0.3 can work well when you want to preserve the original structure while changing its lighting or color treatment. A stronger setting around 0.6–0.7 can be useful when you’re looking for a more substantial transformation, such as developing a rough sketch into a fully rendered anime illustration.
Use reference images to edit AI anime art
Reference images give the model visual information to work from alongside your instructions. This is useful when describing the desired appearance in words isn’t enough, such as when you want to preserve a character’s features, reproduce a particular pose, or combine visual elements from different sources.
With PixAI Reference Pro, you can use reference images to guide an edit while describing the desired result in natural language. For example, one image can provide the character’s appearance while another supplies a pose or composition. An instruction might be:
Keep the character’s face, hair, and outfit from the first reference, but use the pose and composition from the second reference.
Improve the image after editing
Once the main edits are done, give the image a final quality pass before using it elsewhere. This is where you can increase its resolution and check the result for small details that may need one last correction.
Upscale the finished artwork
Once you’re happy with the composition and edits, you can upscale AI anime artwork to increase the image’s resolution for a sharper final result. PixAI’s Upscaler is designed for this finishing stage and helps enhance (while preserving) details such as anime line art, facial features, and fine textures as you move to a larger output.
It’s best to upscale your artwork after the major edits are complete. That way, you’ll be working on the image you actually want to keep rather than repeatedly upscaling versions that may still change. If you’re preparing artwork for a larger display or publication, this is also a good point to choose the final output size.
Make final corrections
After upscaling, inspect the image at a higher zoom and look for small issues that weren’t obvious at the original resolution. You might find stray lines, awkward details, or areas where the generated texture doesn’t quite match the surrounding artwork.
If you spot something that needs attention, make a small inpainting edit rather than changing the whole image. Keep the correction focused, review the result again, and you’ll have a finished version ready for its intended use.
Practical editing workflow: Moving one character through multiple stages
To give you a clearer idea of the PixAI editing workflow, let’s create a character and take it through several editing stages.
We’ll work with an anime illustration of a young fantasy courier arriving at a coastal town. She’s carrying a satchel, wearing a short blue jacket, and standing beside a harbor at sunset.
The initial generation is strong overall, but the hand holding the satchel strap is distorted. The outfit also needs changing for a winter scene, and the portrait doesn’t give us enough room to show the harbor.
Edit 1: Fix the hand with inpainting
The character’s face, pose, and clothing already work, so there’s no reason to regenerate the entire image. Open the artwork in PixAI’s Inpaint Editor and mask only the distorted hand.
Use:
anime hand, five fingers, natural grip, holding a leather satchel strap, clean detailed line art
Keep the mask tight enough to protect the character’s sleeve and satchel. Generate a few variations and choose the hand that connects most naturally with the existing arm.
Edit 2: Turn the outfit into a winter version
The corrected character now works, but the project calls for a colder setting. Instead of changing the whole image, use PixAI Reference Pro to preserve the character’s identity while changing her clothing.
Use the character image as the reference and give it an instruction such as:
Keep the character’s face, hairstyle, hair color, and pose. Replace her blue courier jacket with a cream-colored winter coat, dark gloves, and a burgundy scarf.
This creates a new version of the character while giving us a clear visual connection to the original.
Edit 3: Give the character more room
The original portrait is too tightly framed to show much of the coastal setting. Use PixAI’s Outpaint tool to extend the canvas horizontally and move toward a 16:9 composition.
Prompt the new area with:
coastal harbor town, wooden boats, stone buildings, fishing nets, distant lighthouse, winter evening sky
Now the character has room to exist within a larger environment, rather than simply having a wider background pasted around her.
Edit 4: Change the overall atmosphere
The expanded image still has the warm sunset treatment from the original. To turn it into the colder winter scene we’re aiming for, use Img2Img for a relatively light transformation.
Try:
cold winter evening, pale blue ambient light, soft overcast sky, subtle warm light from harbor windows, atmospheric mist
Start around 0.3–0.4 denoising so the new lighting can influence the whole image while the character and composition remain largely intact.
Edit 5: Prepare the finished artwork
Once the character, composition, and atmosphere are working together, send the image through PixAI’s Upscaler. At this point, the upscaling is a finishing step rather than a way to rescue an unfinished image.
Inspect the enlarged result around the face, hands, clothing details, and newly generated background. If you spot a small problem, return to inpainting for that specific correction.
Which editing method should you use?
The right editing method depends on what you want to change. Ideally, start with the smallest tool that can make the change you need, then move to a broader method when the edit affects more of the image.
| If you want to… | Use… |
| Fix a hand, eye, accessory, or other small detail | Inpainting |
| Change part of a character or outfit | Reference Pro or targeted inpainting |
| Change the overall setting, lighting, or visual treatment | Img2Img |
| Add more space around the existing image | Outpainting |
| Guide an edit using another character, pose, or visual reference | Reference Pro |
| Increase the resolution of a finished image | Upscaler |
Think of these methods as different levels of control. Inpainting gives you precise control over a small area, while Img2Img can influence the image more broadly. Reference Pro is useful when you want visual references to guide a change, and Outpainting gives an existing composition more room.
The key is to choose the method based on the problem you’re solving, rather than applying every editing tool to every image.
Final thoughts
Editing AI anime art gives you much more control over where an image goes after the first generation. Instead of starting again whenever something needs to change, you can preserve the parts that work and refine the areas that need attention.
PixAI brings several editing approaches into the same creative process. Inpainting handles targeted corrections, Reference Pro can guide broader character changes, Outpainting can extend the composition, and Img2Img can reshape the overall look. Once the image is finished, Upscaler can prepare it for a larger final output.
The most useful approach is to treat each tool as a solution to a particular editing problem. Start with a strong image, make focused changes, review each result, and build toward the final artwork one step at a time.
