description

Use when the user has an existing image that needs editing, upscaling, background removal, cropping, outpainting, extending, retexturing, or style transformation. Also use when an image generated by another tool (fal, DALL-E, Stable Diffusion, etc.) needs refinement, cleanup, or enhancement via Midjourney's editor. Triggers on "upscale this", "remove the background", "extend this image", "crop wider", "make this higher res", "clean up this image", "edit this image in midjourney", "outpaint", "inpaint", "retexture".

Editing and Manipulating Images with Midjourney via Playwright

Use Midjourney's editor and image reference features to refine, upscale, extend, or transform existing images -- including images generated by other tools like fal, DALL-E, or Stable Diffusion.

Prerequisites

• Playwright MCP plugin must be installed and available
• User must have an active Midjourney subscription
• User must be logged in to midjourney.com

Use Cases

Upscaling / Super-Resolution

For images that need higher resolution:

1. Upload the image to Midjourney as an image prompt
2. Use a minimal text prompt describing what's in the image
3. Set --iw 2 or --iw 3 (high image weight) to stay faithful to the original
4. Generate, then use Upscale > Subtle for clean 2x resolution boost

Background Removal / Replacement

1. Upload the image to the Midjourney editor
2. Use the Erase brush to paint over the background
3. Write a new prompt describing the desired background (or "transparent background, isolated subject")
4. Submit edit

Outpainting / Extending Canvas

To make an image wider, taller, or extend in any direction:

1. Open the image in Midjourney's editor at /editor/new
2. Use the resize handles to drag edges outward in the desired direction
3. Select a new aspect ratio if needed (e.g., 16:9 from a square)
4. Write a prompt that describes what should fill the extended area
5. Submit edit -- Midjourney will seamlessly generate the extended regions

Inpainting / Object Removal

To remove or replace specific elements:

1. Open image in the editor
2. Use Erase brush or Smart Select to select the area to change
3. Write a prompt describing what should replace it (or leave blank to remove)
4. Submit edit

Retexturing / Style Transfer

To change the visual style while keeping composition:

1. Open image in the editor
2. Switch to the Retexture tab
3. Write a prompt describing the new style (e.g., "watercolor painting", "cyberpunk neon")
4. Submit -- Midjourney retextures while preserving structure

Using Images as References

To generate new images influenced by an existing one:

As image prompt (composition + content influence):

https://uploaded-image-url.png a majestic landscape --iw 1.5

As style reference (style only):

a portrait photograph --sref https://uploaded-image-url.png --sw 200

As character/omni reference (character consistency):

running through a forest --oref https://uploaded-image-url.png --ow 200

Uploading Images to Midjourney

Via the Prompt Bar

1. Click Add Images button (left side of prompt bar)
2. Upload the image file or paste a URL
3. The image appears as a thumbnail in the prompt area
4. Add text prompt and parameters after the image

Via the Editor

1. Navigate to https://www.midjourney.com/editor/new
2. Upload an image to start editing
3. Use editor tools (erase, resize, retexture) to modify

Getting a URL for Local Images

If you have a local image file, you can upload it to Midjourney's prompt bar directly using the "Add Images" button. For URL-based workflows, the image needs to be accessible via URL.

Editor Navigation

URL	Purpose
/editor/new	Start fresh with uploaded image
/edit/{job-id}?index=N	Edit an existing Midjourney generation

Editor Tools

Tool	Purpose
Erase brush	Paint areas to regenerate (inpainting)
Restore brush	Undo erased areas
Smart Select	AI-powered region selection
Resize handles	Drag edges to extend canvas (outpainting)
Retexture tab	Apply new styles preserving structure

Aspect Ratio Presets (Editor)

1:1, 3:4, 2:3, 9:16, 1:2, 4:3, 3:2, 16:9, 2:1

Tips for Editing External Images

• High image weight (--iw 2 or --iw 3) keeps the output faithful to your source
• --raw mode helps preserve photorealistic qualities from the original
• Use Upscale > Subtle (not Creative) when you want to preserve the original look
• For images from fal/SD/DALL-E that need cleanup, the editor's inpainting is great for fixing hands, faces, or artifacts
• Retexture is powerful for converting between styles while keeping layout intact
