Midjourney has recently made “editing images” much more convenient: you can not only make local adjustments to images you generated yourself, but also directly upload local images and, in the web editor, extend, crop, repaint, and even switch materials and overall mood with one click. This article follows the actual workflow to clearly explain Midjourney’s external image editor and its image retexturing mode.
1. What the external image editor can do: expand, erase, inpaint
In Midjourney’s editor, you can upload images from your computer, then use “select an area + prompt” to add elements, remove clutter, replace backgrounds, and more. A common approach is to first expand the canvas (change the aspect ratio or extend outward), then use repainting to “fill” blank areas into the same scene. Compared with repeatedly using Vary in Discord, this kind of “edit exactly where you point” experience is closer to a conventional photo-editing workflow.
2. Image retexturing mode: keep the structure, change lighting and materials
If you like the composition but don’t like the materials, lighting, or overall texture, you can use Midjourney’s “image retexturing mode.” It first estimates the scene’s form and structure, then overlays new textures and surface properties, letting the same image quickly become different looks such as “rainy neon night,” “vintage film,” or “matte terracotta.” In practice, it’s recommended that your prompt prioritize materials and lighting (e.g., “brushed metal, soft rim light, rainy reflections”) and use fewer action words that would change the structure.
