Midjourney Web Image Editor Upgrade Guide: Local Erase, Restore, and Canvas Expansion

3/13/2026

Midjourney has recently rounded out its web-based image editing capabilities, so editing is no longer just “done after generation.” This upgrade focuses on a new “Edit” entry point, local erasing and restoring, and expanding the canvas by adjusting aspect ratio. Below, following the real operation path, we’ll quickly walk you through what Midjourney’s new web features can do and how to use them more smoothly.

The New “Edit” Entry Point: A More Centralized Web Workflow

After opening a piece in Midjourney’s web app, clicking the “Edit” button takes you into a brand-new editing interface where commonly used tools are gathered in one place. Compared with the old habit of switching back and forth between actions, the new interface is more like linking “generate—fine-tune—regenerate” into a complete workflow.

If you usually manage your work on the web, Midjourney’s browsing experience is also more efficient: after opening any image in your library, you can use the mouse wheel to quickly scroll through images continuously, saving time when picking the version you want to edit.

More Intuitive Local Edits: How to Pair Erase and Restore

This time, Midjourney has added “Erase” and “Restore” tools on the web, which are great for dealing with parts of an image you don’t want while still being satisfied with the overall result. For example, extra passersby, background clutter, or flaws along a subject’s edges—you can erase the target area first, then let the system fill it in based on the surrounding context.

It’s recommended to test results with small-area erases first, and use “Restore” as needed to bring back areas you erased too aggressively. The benefit is fewer rounds of repeated regeneration, making Midjourney feel more like a controllable image editor rather than something you can only rely on luck with.

Canvas Expansion and Aspect Ratio Adjustment: “Add More Frame” When Composition Isn’t Enough

The new editor supports expanding the canvas by adjusting size and aspect ratio, which is especially friendly for posters, covers, and banners. You can take an originally more square image and expand it into a wider or taller canvas, then let Midjourney extend the background and details into the newly added areas.

In practice, decide the “final use” aspect ratio first: social media covers, product main images, and article header images can have very different ratios. Expand the canvas into place first, then do local erasing or enhancements—the overall result will be more stable.

Transform, Enhance, and Regenerate: Use the Right Order to Avoid Detours

Midjourney’s web app also provides features such as “Transform,” “Enhance,” and “Regenerate,” allowing you to iterate continuously on the same image. In general, it’s recommended to do composition-related operations first (expand canvas/transform), then fix flaws (erase/restore), and finally improve texture and quality (enhance) or try style variations (regenerate).

If your goal is “same composition, different details,” prioritize Regenerate; if your goal is “same details, higher clarity,” then use Enhance. Treating Midjourney as a reusable editing pipeline will be more controllable than generating from scratch each time.
