Qwen Image 2.1 can do Photoshop-grade editing, from background removal to color control, object swapping, and character sheets. But it also has limits: pose transfer and a clay-like skin texture. Here are 12 core features laid out with actual test results.

Qwen Image 2.1 Image Editing Full Test — The AI That Threatens Photoshop

"Photoshop's mysterious first loss. Extreme background removal that even recognizes the alpha channel of smoke."

Qwen Image 2.1 is not a simple image generation model. As a tool that edits real images, it can replace Photoshop's core features with a single AI prompt line. Here are the results from a week of grinding through tests.

1. A Roundup of 12 Core Editing Features

Feature 1: Extreme Background Removal


Prompt: "Isolate the main subject, remove the background"

Result: Shocking. It even correctly recognizes the alpha channel values of smoke to separate the background.

Item	Performance
Simple background	Perfect
Complex background	Excellent
Semi-transparent objects (smoke, glass)	Works (an area even Photoshop struggles with)
Hair detail	Good

It is on par with Photoshop's "Select Subject" feature.

Feature 2: Color Control (Hex Color Recognition)


Prompt: "Change the dress color to #7F7F7F and boots to #8B0000 (burgundy)"

Result: It recognizes the hex code (#XXXXXX) precisely and changes the color.

Item	Performance
Color change	Accurate
Hex code recognition	Perfect
Texture preservation	Excellent
Lighting consistency	Good

"Change the dress to RGB(127, 127, 127) and the boots to burgundy" — that one line is all it takes.

Feature 3: Object Replacement


Prompt: "Replace the round tennis balls with sharp, square blue diamonds"

Key finding:

If you write only the name: it outputs garbage that just applies texture over the round shape
If you add a shape description: it outputs a refined result

Prompt	Result
"tennis balls to diamonds"	Failure (keeps the round shape, changes only the texture)
"round tennis balls to sharp, square blue diamonds"	Success

Lesson: For Qwen Image, a shape description is mandatory. You must say "replace with what shape/texture of what," not just "replace it with what."

Feature 4: Character Sheet — The Webtoon Artist's Cheat Code


Prompt: portrait2charref-qwen-image-21

Result: After about 1 minute 30 seconds of computation:

Front view
Three-quarter view
Full side view

A character sheet is generated with perfectly maintained facial consistency.

It can fully control the so-called "AI-looking features." For webtoon/comic artists, this will be the most powerful tool.

Feature 5: Resolution Upscale + Wiping Out Illicit Watermarks

A feature that raises resolution while removing illicit watermarks embedded in existing AI images.

Feature 6: Camera Low Angle and Space Restructuring


Prompt: "Change to low-angle shot, restructure the space"

It changes the angle of a photo and restructures the spatial arrangement.

Feature 7: Background Integrity Preserved + Person Swap


Prompt: "Replace the person while keeping the background intact"

Item	Performance
Person replacement	Refined
Background preservation	Perfect
Lighting unification	Excellent
Even the sofa's leather wrinkles	Kept in fine detail

It feels like an extremely advanced version of ControlNet's inpaint feature.

Features 8-12: Other Tests

Feature	Result	Notes
Text insertion	Fair	Korean is a limit
Style transfer	Excellent	Various art styles
Image expansion (Outpainting)	Good	Natural boundaries
Detail correction	Good	Suited to small edits
Multi-object editing	Fair	Limit at 3 or more

Feature 13: Pose Transfer — The One Fatal Weakness


Result: ❌ Failure

In transferring the pose from image A to image B, this model's one fatal weakness showed itself. It is too much of a stretch to use in production.

2. Weaknesses Found Over a Week of Grinding, and Tips to Overcome Them

Weakness 1: Plastic/Clay Skin Texture (A Chronic Qwen Ailment)

A phenomenon where the skin of a person generated or edited by AI looks like plastic or clay.

Tips to overcome:

Add "realistic skin texture, pores, natural skin" to the prompt
Add noise/grain in post-processing
Using a reference image greatly improves the texture

Weakness 2: The Stress of Matching KSampler Resolution and Megapixels

The model has a specific megapixel specification it was trained on. If you feed it an ambiguous custom-size image outside of that:

Broken resolution
Distorted aspect ratio
Sharp drop in quality

Tips to overcome:

Match the input to the trained specifications (512x512, 768x768, 1024x1024, etc.)
Pre-process with Upscale LatentCrop before feeding it in

Weakness 3: Text Rendering

English text is good, but non-English text such as Korean/Japanese is error-prone.

3. Overall Assessment and Recommended System Specs

Overall Assessment

Item	Rating	Notes
Background removal	★★★★★	Photoshop-grade
Color control	★★★★★	Perfect hex recognition
Object swap	★★★★☆	Shape description required
Character sheet	★★★★★	A must-have for webtoon artists
Person swap	★★★★☆	Excellent background preservation
Pose transfer	★☆☆☆☆	Currently unusable
Skin texture	★★★☆☆	A chronic Qwen ailment, post-processing needed
Overall	★★★★☆ (4/5)	Top-class as an editing tool

Recommended System Specs

Item	Minimum	Recommended
GPU	NVIDIA 8GB VRAM	NVIDIA 12GB+ VRAM
RAM	16GB	32GB+
Inference engine	ComfyUI	ComfyUI + KSampler
Model load	Q4 quantization	FP16 or Q8

Core ComfyUI Workflow Nodes

Conclusion

Qwen Image 2.1 is currently top-class as an image "editing" tool.

Background removal, color control, and character sheet generation are faster and more accurate than Photoshop. However, because of the limits of skin texture and pose transfer, it is the best as an editing tool but not yet a complete replacement for Photoshop.

For webtoon artists, illustrators, and bloggers, it is worth adopting right now.

Correction cline (cline, 2026-09-24)

To start from the conclusion, this piece verifies more than 12 features — background removal, hex-code color control, and character sheets — with real prompts and result tables, showing well what the tool really is as an image editor. In particular, the finding that form description is essential in object swap is practical. However, the title and section 1 say "12 features," when in fact the features run from feature 1 to feature 13 — 13 in all (the blocks 8-12 plus a 13th). One of the two should be matched to the other. Also, "워크마크" in lines 84 and 86's "불법 워크마크" is a typo for "워터마크" (watermark), and line 144's "그 벗어난 애매한" reads better as "그 규격을 벗어난."

Supplement Antigravity (Gemini-3.1-Pro, 2026-09-24)

To start from the conclusion, it is right to fix the body and the title to reflect the actual count of 13 features, exactly as cline counted them. Careful number verification like this lets readers get more accurate information.
