Midjourney’s web version has recently made “Edit” much easier to use: enter a more focused editing interface with one click, where you can both erase and repaint parts of an image and expand the canvas outward by adjusting the aspect ratio. For those who don’t want to rerun prompts over and over, these two features directly change output efficiency. Below is a clear, practical walkthrough of Midjourney’s new features.
1) Where the “Edit” button is: go straight from a work to the workspace
In the Midjourney web version, open any previously generated piece; you can usually see a clearly labeled “Edit” entry. After clicking it, you’ll enter a more focused editing interface, with tools on the left and parameters plus actions on the right. The value of this workflow is that you don’t need to start an entirely new generation—you can keep refining the same image.
2) Erase: remove first, then let Midjourney fill it in
“Erase” is more like local repainting: use a brush to paint over areas you’re not satisfied with, such as extra passersby, a background mistake, or an accessory with the wrong shape. After erasing, Midjourney will regenerate the blank area so it naturally “grows” back into the original composition. A practical tip is to start with small areas—fix key flaws first, then gradually expand the edited region for a higher success rate.
3) Restore: if you erased by mistake or too much, undo more reliably with one click
If you erase something you shouldn’t have, “Restore” can bring back the removed area. It’s great for boundary control: erase a larger patch boldly, then use Restore to “add back” the subject’s outline, so Midjourney repaints only the part you truly want to change. For detail-oriented users, this is the most noticeable improvement in the web editing experience.
4) Expand the canvas: pull the composition outward via scale/aspect ratio
Beyond touch-ups, Midjourney also supports enlarging the canvas by adjusting the scale and aspect ratio. Common uses include turning a vertical image into a banner, expanding a headshot into a half-body shot, or adding more negative space for the scene—making it smoother for posters and cover images. It’s recommended to decide the target format first (for example, a wider horizontal ratio) and expand in one go, to avoid multiple expansions that can make edge details unstable.
5) Best-fit scenarios: rerun less, iterate more
This web update is most suitable for three kinds of needs: first, fixing the small flaws common in Midjourney generations; second, keeping the subject unchanged while replacing only local elements; third, adding compositional breathing room to the same image. As long as you treat Midjourney as a tool for “draft first, then fine-tune,” making good use of the Edit entry, Erase/Restore, and canvas expansion will make image output feel much more like a real design iteration workflow.
