Midjourney Parameter Builder
100% PrivateAI & Prompt ToolsBuild a Midjourney prompt suffix visually, with aspect ratio, version, style and quality settings.
Runs entirely in your browser. Your input is not uploaded to Ovatly or anywhere else.
Parameter list snapshot: November 2026. Midjourney changes its parameters between versions; check the current Midjourney documentation for the version you use.
Describe the image first; the parameters are added after your description.
- --ar: Shape of the image, written as width:height, for example 16:9 for widescreen or 1:1 for square.
- --v: Which Midjourney model version renders the image. Newer is not always better for a given style.
- --stylize: How strongly Midjourney applies its own artistic style. Low values stay closer to your words, high values look more polished and less literal.
- --chaos: How varied the first four results are. Higher values explore stranger directions.
- --quality: How much rendering time is spent on detail. Higher quality costs more GPU time.
- --style raw: Reduces Midjourney's automatic beautification, giving a more literal, photographic result.
- --tile: Makes the image repeat seamlessly, for patterns and textures.
- --cref: Paste the URL of an image whose character should stay consistent in the new image.
- --sref: Paste the URL of an image whose visual style should be matched.
- 1Write your image description first; parameters always come after it.
- 2Pick an aspect ratio preset or type a custom one like 5:4.
- 3Set version, stylize and chaos only if you want non-default behavior.
- 4Add reference URLs or tiling if needed, then copy the finished prompt into Midjourney.
Description: "a lighthouse at dawn, waves crashing"; Aspect ratio 16:9; Version 6.1; Stylize 250; Chaos 10; Style raw on. Result: "a lighthouse at dawn, waves crashing --ar 16:9 --v 6.1 --stylize 250 --chaos 10 --style raw"
- The parameter list is a snapshot dated November 2026. Midjourney retires and renames parameters between versions, so check the current Midjourney documentation for the version you actually use.
- Niji versions are written as --niji 6, not --v; the builder handles that when you pick the Niji option.
- This tool only assembles text. It has no connection to Midjourney and cannot submit or preview your prompt.
It controls how strongly Midjourney applies its own house style. Low values (near 0) follow your description more literally; high values (up to 1000) look more polished but drift further from your words.
About this tool
The Midjourney Parameter Builder turns the fiddly suffix of a Midjourney prompt into form fields: aspect ratio, model version, stylize, chaos, quality, style raw, tiling and character or style reference URLs. Set what you need, leave the rest at defaults, and the tool appends the correct --parameters to your image description in the standard order, with a plain-English explanation of every parameter on the page.
