That almost-perfect AI portrait doesn't have to be thrown away. Here's how to fix it.
You generated an image that's 95% exactly what you wanted. The composition is perfect. The lighting is gorgeous. The mood is exactly right. And then there's the face — slightly off, weirdly smooth, one eye slightly different from the other, or in a full-body shot, a blurry smudge where a face should be.
It's one of the most frustrating experiences in AI art creation. And for a long time, the only answer was to regenerate and hope the next result happened to be better — an approach that wastes credits, wastes time, and regularly produces the same problem in a slightly different way.
The actual solution is inpainting: the ability to mask a specific area of an image, describe what should be there, and let an AI regenerate only that region while leaving everything else untouched. Done correctly, it's a surgical fix — you keep the 95% that works and replace the 5% that doesn't.
This guide covers exactly how to do that for faces specifically, using the best desktop inpainting tools available in 2026 — from beginner-friendly browser tools to the powerful local desktop pipelines that give you full control.
Understanding Why AI Faces Break Down
Before getting into the tools, it helps to understand why face inconsistencies happen — because the cause shapes the fix.
Small faces in full-body images are the most common problem. In Stable Diffusion, faces are often garbled if they are too small. ADetailer crops out a face, inpaints it at a higher resolution, and puts it back. The issue is that AI image models work in a fixed resolution space, and a face that only occupies a small fraction of that space doesn't have enough pixel detail to render correctly. The model does its best with what little information it has, and the result is a blurry, malformed, or inconsistent face.
Multi-character images present a different challenge: each face gets less resolution to work with, and the model has to balance consistency across multiple subjects simultaneously. Even a single slightly different prompt interpretation for one face can make two people in the same image look like they were generated separately and composited together.
Iterative generation — refining an image multiple times — can introduce drift. A face that looked right after the first generation may look slightly different after regenerating with a modified prompt or different seed.
In all of these cases, inpainting is the correct tool. The goal is to isolate the face, give the AI more resolution and more focused attention to regenerate it, and blend the result back into the surrounding image seamlessly.
The Two Approaches: Browser Tools vs. Local Desktop Tools
There are two categories of inpainting tools worth knowing, and the right choice depends on your setup and technical comfort level.
Browser-based tools — Photoshop Generative Fill, Adobe Firefly, PixVerse, and others — are accessible from any device, require no installation, and work well for straightforward fixes. Adobe Photoshop introduced Generative Fill in 2023 and it changed the way people think about image editing. Select an area, type a prompt, and watch the AI fill it in with something entirely new. These are the right starting point for most users.
Local desktop tools — AUTOMATIC1111, ComfyUI, and Stable Diffusion WebUI Forge — run on your own machine and offer far greater control, no usage fees, and no rate limits once set up. Unlike Midjourney or DALL-E 3, local Stable Diffusion has no usage fees, no content filters, and no rate limits. You can generate thousands of images per day at zero marginal cost once the hardware is set up. These are the tools serious AI artists rely on for production-level work.
This guide covers both — starting with the accessible options and moving into the more powerful local setups.
Tool One: Adobe Photoshop Generative Fill
For users who are already in the Adobe ecosystem, Photoshop's Generative Fill is the most accessible professional inpainting tool available. It integrates directly into the Photoshop workflow you already know, uses Adobe's Firefly model, and produces results that blend well with surrounding image content.
How to use it for face fixing:
1. Open your image in Photoshop
2. Use the Lasso tool to draw a selection around the face area — include a small amount of the surrounding hair, skin, and neck so the model has context for blending
3. With the selection active, click Generative Fill in the Contextual Task Bar (or go to Edit → Generative Fill)
4. In the prompt field, describe what you want: "realistic face, consistent lighting, natural skin texture, [describe the character's features — age, gender, expression]"
5. Click Generate — Photoshop will produce three variations in a new layer group
6. Cycle through the variations and pick the best one
Key tip: The prompt you write for Generative Fill should describe the face you want, not what was wrong with the original. Don't write "fix the blurry face." Write "natural human face, woman in her 30s, soft directional lighting, realistic skin texture, consistent with the rest of the image."
Photoshop and Firefly fit professional production because layers, masks, and manual refinement matter after the AI edit. The non-destructive layer structure means you can always go back, compare variations, and blend manually if the AI result needs slight adjustment around the edges.
Best for: Professional users who need a reliable, integrated workflow. Requires a Creative Cloud subscription.
Tool Two: AUTOMATIC1111 (A1111) — The Beginner's Local Powerhouse
AUTOMATIC1111's WebUI is built for accessibility and quick experimentation. Most advanced features — ControlNet, LoRA fine-tuning, inpainting — are available as extensions installable from the Extensions tab. It runs locally in your browser, works on Windows, Mac, and Linux, and is free and open source.
For face inpainting specifically, A1111's img2img inpainting tab is purpose-built for exactly this workflow.
The basic inpainting workflow in A1111:
Click the Send to Inpaint icon below the image to send the image to img2img → inpainting. You should now be on the img2img page and Inpaint tab.
From there:
1. Use the brush tool to paint a mask over the face area — paint slightly beyond the face edges to include surrounding hair and skin for better blending
2. Set Inpaint masked (not the whole image)
3. Set Mask blur to 8–32 pixels — this feathers the edge of your mask so the inpainted area blends smoothly rather than looking pasted in
4. Set Denoising strength between 0.5 and 0.75 — lower values stay closer to the original, higher values give the AI more freedom to regenerate. For faces, 0.55 to 0.65 is usually the sweet spot
5. Write a focused prompt describing the face: what it should look like, the lighting, the skin quality
6. Set sampling steps to 20–30
7. Generate
Include a little hair around a face, or a bit of sleeve near a hand, so the model can blend better. This small habit — slightly overshooting the mask boundary — makes a significant difference in how naturally the inpainted area blends.
Hardware note: Hardware requirements vary by model size. A1111 runs well on NVIDIA GPUs with 6GB+ VRAM. Apple Silicon Macs are supported. For users without a capable GPU, cloud services like Think Diffusion offer managed A1111 instances you can access from any browser.
Tool Three: ADetailer Extension — Automatic Face Fixing
If you're already using A1111 and want face fixing to happen automatically as part of every generation — without manually inpainting each image — the ADetailer extension is the answer.
When crafting full-body portraits or images where the subject is at a distance, you might observe faces becoming blurred or distorted. When facing this challenge, it's a strong indicator that the ADetailer extension could be your solution.
ADetailer works by automatically detecting faces in your generated image, cropping them out, inpainting them at a higher resolution with your chosen prompt, and compositing the improved faces back into the original image. It all happens in a single generation pass — you don't have to do anything manually.
Setting it up:
1. Install ADetailer from the Extensions tab in A1111 (search for "ADetailer" in the Extensions browser)
2. Restart A1111
3. In your text-to-image or img2img settings, find the ADetailer accordion panel and check Enable ADetailth
4. From the ADetailer model dropdown, select `face_yolov8n.pt` — this is the recommended face detection model
5. In the ADetailer prompt field, write a description of the face quality you want: "highly detailed face, natural skin texture, consistent lighting, realistic eyes"
From blurred faces to distorted features, ADetailer delivers efficient and effective restoration. This guide has showcased the extension's capabilities, from prompt customization to the use of YOLO models for accurate detection.
Once set up, ADetailer runs silently on every image and dramatically improves face quality without any additional workflow steps. For creators generating large batches of character images, this is the single highest-impact quality improvement available.
Tool Four: ComfyUI with FaceDetailer — For Advanced Workflows
ComfyUI is the node-based alternative to A1111 — more complex to set up, but significantly more flexible and better suited to production pipelines and batch workflows.
ComfyUI uses a node-based workflow canvas similar to visual programming tools. A1111 uses a traditional web form interface that is easier for beginners but less flexible.
For face fixing specifically, ComfyUI's most powerful tool is the FaceDetailer node, part of the Impact Pack extension.
You can use FaceDetailer node with the Impact Pack in ComfyUI. Adetailer crops out a face, inpaints it at a higher resolution, and puts it back. You can do the same with the FaceDetailer node with the Impact Pack in ComfyUI.
Installing the Impact Pack:
1. Install ComfyUI Manager if you haven't already
2. In ComfyUI Manager, search for "Impact Pack" and install it
3. Restart ComfyUI
4. Add the FaceDetailer node to your workflow
The FaceDetailer node sits at the end of your image generation workflow and takes the output image, detects faces, runs a targeted inpainting pass on each detected face, and returns the improved image. You can control the detection confidence threshold, the denoising strength, the mask padding around the face, and the prompt used for the inpainting pass.
For multi-character images, FaceDetailer detects and improves each face independently — which solves the consistency problem at its source rather than trying to fix it after the fact.
Best for: Advanced users building production workflows, batch processing pipelines, or anyone already working in ComfyUI who wants automated, high-quality face improvement at scale.
Tool Five: Ideogram V3 — For Online Inpainting Without Local Setup
For users who want professional-grade inpainting without installing anything locally, Ideogram V3 supports prompt editing, inpainting, and outpainting with native mask support and built-in style presets. The model is particularly strong at maintaining text elements in images and offers an inverted mask option for more precise control.
Ideogram's inpainting interface is clean and accessible: upload your image, use the brush tool to mask the face area, write a prompt, and generate. The native mask support means precise selections, and the inverted mask option lets you tell the AI to change everything *except* a specific area — useful when you want to regenerate a face while perfectly preserving an intricate background.
Ideogram V3 supports prompt editing, inpainting, and outpainting with native mask support and built-in style presets... excellent price-to-quality ratio.
Best for: Users who want better results than Photoshop Generative Fill without the complexity of local Stable Diffusion setup.
Masking Best Practices for Face Inpainting
Regardless of which tool you use, how you draw the mask over the face area significantly affects the quality of the result. These habits apply universally:
Slightly overshoot the face boundary. Mask the face and an additional 10–20 pixels of surrounding skin, hair, and neck. This gives the AI enough context to blend the inpainted area naturally into the surrounding image. A mask that cuts tightly to the face edge will produce a visibly pasted-in look, even with good inpainting.
Match your prompt to the surrounding image. If the rest of the image has warm, golden-hour lighting, describe that in your face prompt. If the character has a specific age or expression, describe it. The inpainting model is trying to match the surrounding context — help it by being explicit about what that context demands.
Use moderate denoising strength. A denoising strength of 0.5–0.65 preserves more of the original face structure while still allowing the AI to fix the problem areas. Going above 0.75 risks changing the face so much that it no longer matches the character's identity across a set of images.
Generate multiple variations. Most inpainting tools generate multiple options. Always generate at least two or three, compare them, and pick the one that fits best. The first variation is rarely the best one.
Keep a copy of the original. Work non-destructively where the tool allows. In Photoshop this means using adjustment layers. In A1111 and ComfyUI, always save the original before inpainting. Inpainting is not perfectly predictable — you want to be able to go back.
Choosing the Right Tool for Your Workflow
Here's a quick decision framework:
You're a Photoshop user who wants the simplest possible fix: Use Generative Fill. It's integrated into your existing workflow, produces good results for straightforward face corrections, and requires no additional setup.
You want powerful local control and don't mind a setup process: Install A1111 and the ADetailer extension. This combination handles face fixing automatically on every generation and gives you fine-grained manual control when you need it.
You're building a production pipeline or working with batch image processing: ComfyUI with FaceDetailer is the most scalable and customizable option. The setup investment pays off quickly if you're working at volume.
You want browser-based power without Photoshop's price tag: Ideogram V3 offers native mask support, strong inpainting quality, and an accessible interface with no installation required.
That almost-perfect AI portrait was never a lost cause. It was an inpainting job waiting to happen. The tools to do it properly — automatically, precisely, and at any scale — are all available right now, and most of them are either free or available on affordable subscriptions.
The 95% that works was worth saving. Now you know how.
