Midjourney Web Image Editor Launches: Erase/Restore, Canvas Expansion, and Transform

Midjourney has added a brand-new image editor to the web version. The entry point is more intuitive, and the controls feel more like common photo-editing tools. You can enter the new interface via the “Edit” button, use “Erase” and “Restore” to refine specific areas, expand the canvas by adjusting scale and aspect ratio, and take advantage of the new “Transform” capability for overall adjustments.

What’s new in this Midjourney image editor update

This time, Midjourney’s focus isn’t on swapping in a new set of button skins, but on moving the “edit after generating” workflow into a more complete web-based interface. According to the official update notes, the Midjourney image editor provides “Erase” and “Restore” tools for making changes to specific areas of an image or undoing edits.

Another change is that outpainting is more flexible: you can adjust scale and aspect ratio to expand the canvas, rather than being limited to adding padding in fixed directions. The page layout is also better for browsing and selecting images; for example, scrolling through your work in “my images” is noticeably more efficient.

How to enter the editing interface on the web (shortest path)

Open your list of works in the Midjourney web app (a common entry is my images), and open any image you want to work on. Find the “Edit” button near the image area; clicking it will take you into the new Midjourney image editor interface.

If you usually have a lot of images, it’s recommended to first use the web’s quick browsing to locate the target image, then enter editing: in the single-image viewing mode, use the mouse wheel to switch quickly, confirm the asset, and then click “Edit”—this can save a lot of back-and-forth navigation time.

How to use “Erase / Restore”: more reliable local edits

In the Midjourney image editor, “Erase” is suitable for removing unwanted details (such as extra objects, edge blemishes, or small glitchy areas). The idea is to first erase the area that needs to be redone, then rely on the generate/repaint logic to have the system fill it in with more reasonable content.

“Restore” is more like an undo button: if you erased too much, the edges aren’t clean, or you realize the original detail looks better, use “Restore” to bring parts back. A practical tip is to work in small areas and iterate multiple times—don’t erase large portions of the main subject at the start; Midjourney’s inpainting tends to be more stable when it can rely on “local area + surrounding context.”

Canvas expansion and “Transform”: good for layout and composition adjustments

When making posters, covers, or anything that needs space for text, Midjourney’s “Expand Canvas” is very useful: by adjusting scale and aspect ratio, you can turn a square image into a horizontal banner or vertical format, then let the system fill in the new areas. Compared with forcing an expansion in only one direction, this approach is closer to real design workflows.

In addition, “Transform” provides an entry point for more global adjustments, suitable for structural changes without overturning the image’s style. My suggestion is: first use canvas expansion to lock in the dimensions, then use erase/restore to clean up edges and details, and finally consider whether you need Transform for overall fine-tuning. This makes Midjourney’s editing workflow smoother and makes it easier to get a usable final image.
