Getting started with Midjourney Web Image Editor’s new features: smoother erase/restore and canvas expansion

Midjourney’s Web image editor has added a more user-friendly set of editing entry points and tools. Now you can not only refine specific areas more precisely, but also save your composition by expanding the canvas. Below, following the actual workflow, I’ll explain these new Midjourney features clearly.

1. First, find the “Edit” button: the entry point is more intuitive

Open an existing creation on Midjourney’s web version and you’ll see the new “Edit” button. After clicking it, you’ll enter the improved editing interface, where commonly used tools are gathered in one place, so you don’t have to hunt around back and forth.

For people used to clicking buttons in Discord, this change is crucial: Midjourney has turned “post-generation editing” into a clearly defined workflow, so editing is no longer just an extra, tacked-on feature.

2. Erase and Restore: local edits are finally controllable

Midjourney has added two tools in the editor—“Erase” and “Restore”—which are suitable for handling small-area flaws. For example, a character’s hands, extra bystanders in the frame, or background clutter can all be handled by first erasing a selected area, then letting the system fill it in according to your intent.

If you erase too much, there’s no need to panic—just use “Restore” to brush the area back, avoiding having to start over repeatedly. This combination makes Midjourney’s local edits feel more like “refinements with undo,” rather than a one-shot gamble.

3. Expand canvas and adjust aspect ratio: switch composition between landscape and portrait in one click

The new editor supports enlarging the canvas by adjusting the size and aspect ratio. A common scenario is: the original image is beautiful but too square; when you want to make a poster or cover, there isn’t enough space on the sides. Now you can expand the canvas first, then fill in the environment and lighting.

The advantage of doing this in Midjourney is better stylistic consistency: the expanded content will try to carry over the original image’s texture and feel, making it less likely to look “stitched together.”

4. Transform, Enhance, Reroll: there’s a path from small tweaks to full do-overs

Beyond local tools, Midjourney has also placed capabilities like “Transform,” “Enhance,” and “Reroll” into the same editing workflow. You can first use Erase/Restore to address problem areas, then use Enhance to boost details; if the overall direction is wrong, use Reroll to generate again.

A practical recommendation is to fix small things before making big changes: resolve the elements that must be corrected first, then decide whether you need to reroll—this can noticeably reduce the trial-and-error cost of generating images in Midjourney.
