Midjourney Web Editor Upgrade: The Edit Button Now Enables Local Erasing and Canvas Expansion

Midjourney’s web-based image editor has recently made “being able to edit images” much more seamless: after generating, you can click “Edit” to enter a new interface, use “Erase/Restore” to repaint specific areas, and expand the canvas by adjusting scale and aspect ratio. This article breaks down Midjourney’s new features and walks you through them step by step.

What’s new in the Midjourney web version this time

Midjourney has added a clearer “Edit” entry point for images on the web: you don’t need to detour through complicated menus—click “Edit” to enter the improved workspace. The core changes fall into two categories: one is local edits (Erase and Restore), and the other is composition-level canvas expansion (changing scale and aspect ratio).

Compared with the past—when you could only reroll repeatedly or make lightweight variations—this approach to the Midjourney web editor is closer to “get the overall direction first, then precisely refine the details.” For small touch-ups to e-commerce images, posters, or character illustrations, efficiency will be noticeably higher.

How to use local editing: the shortest path with Erase and Restore

Open the image you want to modify on the Midjourney web version, click “Edit” to enter the new interface, and first remember two tools: “Erase” and “Restore.” Erase is like cutting out an area; Midjourney will repaint the blank region based on your prompt. Restore is used to undo accidental erasing and bring content back.

In practice, it’s recommended to start small: use a smaller brush to erase the problem area (such as extra fingers, an unintended object, or background text), then in the prompt describe only what you want to “fill back in.” Midjourney’s inpainting depends heavily on “local semantics”—the more focused your wording, the less likely it is to disrupt the surrounding image.

Expanding the canvas and changing proportions: “making room” for composition

Another improvement is canvas expansion: Midjourney’s web version allows you to enlarge the canvas by adjusting scale and aspect ratio, effectively adding generatable space around the edges. Typical uses include: the subject is too close to the border, converting a portrait image into a banner, leaving blank space for copy, or needing more background for extension.

When using it, it’s best to decide the final target ratio first (e.g., cover, poster, horizontal header image), then choose which direction to expand. After expanding, if the subject placement isn’t ideal, you can follow up with a round of local erasing to help Midjourney make the edge transitions look more natural.

More reliable Midjourney editing tips and precautions

First, don’t erase too large an area at once: the larger the region, the more likely Midjourney is to “incidentally” change lighting and texture you were already happy with. Second, write prompts in terms of “what to replace it with,” and write less about “what you don’t want,” to avoid the model misunderstanding you; if you need consistent style, try to stick with the original image’s keyword system.

Also don’t forget: Midjourney’s edits are still generative modifications, so details can be random. When you run into messy edge blending or inconsistent materials, the most practical approach is “multiple small fixes” rather than a single big change—this is exactly the workflow that this Midjourney web editor upgrade is best suited for.
