Midjourney Web Editor Quick Start: Local Erase/Repaint and Canvas Expansion

2/22/2026
ChatGPT

Midjourney’s web version has added a more user-friendly image-editing entry point: after generating an image, click “Edit” to enter the online editor. You can use Erase/Restore for localized repainting, and you can also expand the canvas to change the aspect ratio and fill in the background—linking “generation” directly to “fine retouching.” Below, I’ll explain the key features clearly based on actual操作.

How to enter the Midjourney web editor

On the Midjourney website, open an image you’ve already generated and select the one you want to work on. Find the “Edit” button near the image and click it to enter a new editing interface. This workflow doesn’t rely on Discord commands, making it better suited for detail adjustments and secondary composition.

Erase: Remove an area and let Midjourney automatically fill it in

After entering the editor, choose Erase. Use the brush to paint over elements you don’t want, such as extra passersby, unwanted objects, or small facial imperfections. When you’re done erasing, add a short description (e.g., “clean background,” “remove text,” or “add small flower”), and Midjourney will repaint and fill in the blank area. Practical tip: don’t paint too large an area—try a small region first for a higher success rate.

Restore: One-click rollback for accidentally erased content

If you erased too much, switch to Restore and brush back the area that was removed—essentially a localized undo. This is especially convenient when fixing hands or eyes: erase and repaint to see the result; if you don’t like it, restore, then redo with a smaller selection. Using Midjourney for “controlled trial and error” is more cost-effective than regenerating over and over.

Canvas expansion and transforms: Change aspect ratio, add space, and create extended compositions

In the editor, you can adjust the ratio/aspect ratio and expand the canvas outward—for example, turning a square image into a horizontal poster, adding headroom above a person for a title, or extending a product image sideways for an e-commerce main image. After expanding, it’s recommended to specify what to add while keeping the style consistent, e.g., “extend the same wall texture, keep lighting consistent.” In addition, “Transform” can be used for overall adjustments combined with regeneration operations, which is suitable for minor structural tweaks without starting over.

Quick tip: Lock in the subject first, then use the editor for details

A smoother workflow is: first use Midjourney to generate a solid base image where the subject, lighting, and style are satisfactory, then enter the web editor to handle local edits and composition. If you find the edited result drifting in style, it’s usually because the selection is too large or the prompt is too complex—shrink the selection and use shorter descriptions for more stable results. Some accounts may see a generation-count notice on the web version; refer to what the Midjourney interface displays.
