Midjourney Web Image Editor Upgrade: Hands-On with Erase/Restore and Canvas Expansion

Midjourney has recently completed the web-based image editing experience: it’s no longer just “generate → upscale → generate again,” but lets you make finer local edits and extend the frame on the same image. This article clearly explains how to access Midjourney’s new editing interface and how to use Erase/Restore, Expand Canvas, and Transform, so you can start using it right away.

Where to enter: Find Midjourney’s “Edit” button

After you open an image you’ve generated on the Midjourney web app, the page provides an “Edit” entry. Click it to enter the brand-new editing interface. This interface puts local edits, canvas adjustments, and subsequent generations into a single workflow, reducing back-and-forth switching.

In practice, it’s recommended to pick an image whose composition is close to the final result before entering the editor. That way, Midjourney’s changes behave more like “fine-tuning,” with a higher success rate.

Erase and Restore: Change only the part you want

The most useful tools in the Midjourney editor are “Erase” and “Restore.” Erase is used to mark the area you want to change—such as extra accessories on clothing or distracting clutter in the background. Restore brings back parts you erased by mistake, preventing the erased area from growing larger and larger.

In terms of usage, it’s best to do “small amounts, multiple times”: erase a small area first, then use a short prompt to describe what to replace it with (for example, “clean background,” “remove text,” “replace with a plain wall”). In Midjourney, the more restrained the erased area, the more stable the edit.

Expand the canvas and change aspect ratio: It’s easier to turn a vertical image into a wide banner

This time, Midjourney also strengthened canvas expansion: you can adjust the ratio and aspect ratio to extend the image outward. Common scenarios include posters lacking whitespace, portraits needing shoulder lines added, or product images that need more environmental space—all can be handled by expanding the canvas first and then generating to fill in the rest.

The key is to decide the usage first and then set the ratio: covers often use a wider horizontal format, while social-media avatars tend to be square or vertical. After expanding, add a one-sentence constraint for the new area (e.g., “continue the same background, soft studio light”), and Midjourney will be more likely to keep the style consistent.

Transform: Make structural adjustments on the same image

According to official update information, the Midjourney editor also provides “Transform” capabilities, used for more holistic, reconstructive adjustments to an image. It’s suitable for cases where “the subject is good but the visual relationships aren’t right,” such as shifting the compositional focus slightly to make the image better suited for layout.

It’s recommended to treat Transform as a “last mile” layout tool: first use Erase/Restore to fix details, then use canvas expansion and Transform to organize the image into deliverable dimensions and whitespace. This way, a single image can go through most of the process from rough draft to finished piece within Midjourney.
