Midjourney’s web editor has recently become much more usable. The key changes focus on the “Edit” entry point, localized erase-and-regenerate, and expanding the canvas and changing the aspect ratio. This article takes you along the shortest path to quickly polish Midjourney outputs into deliverables, without repeatedly re-rolling the entire image.
Where the Edit button is: enter the new interface directly from the generation page
When viewing your generation history on the Midjourney website, selecting an image will reveal an “Edit” entry point. Click it to enter the new editor interface. The value of this entry point is that it connects Midjourney’s “generation” and “refinement,” saving you the detour of downloading and then doing secondary processing elsewhere.
Erase and Restore: use localized re-generation to fix unsatisfying details
After entering the editor, Midjourney provides “Erase” and “Restore” tools: Erase removes local content, and Midjourney will regenerate the blank area. If your hand slips or you erase too much, use Restore to revert the area. It’s recommended to start with a small test erase and then expand gradually for a more stable success rate.
Expand the canvas and change the aspect ratio: easier padding, adding whitespace, and restructuring composition
The new Midjourney editor supports enlarging the canvas by adjusting the size and aspect ratio—essentially “adding canvas” around the original image. Common use cases include converting a square image into a vertical poster format, adding whitespace for e-commerce main images, or pulling a subject back from the edge toward a golden-ratio position and then letting Midjourney fill in the extended edges.
Practical workflow: how to polish a Midjourney image in one pass after generating
Step 1: In Midjourney, generate a version close to your target and upscale the one you want. Step 2: Click “Edit” to enter the interface, and first use Erase to remove obvious mistakes (extra fingers, intrusive objects, messed-up letterform areas). Step 3: In the prompt, only add “what you need it replaced with,” such as “change the object in the hand to a glass cup,” to avoid drifting the overall style; finally, expand the canvas as needed for layout.
Usage tips: three tricks to reduce rework
When doing local edits in Midjourney, keep prompts as short and specific as possible—prioritize material, shape, and lighting, and avoid rewriting a long scene description. Leave a bit of transition along the erased edges to help Midjourney blend seamlessly. When expanding the canvas, decide the final aspect ratio first and then extend the edges; it reduces one round of repeated generation and is less hassle.
