Midjourney Sref Code Library

Midjourney can borrow a look from a picture. Point --sref at an image and the model pulls its colour palette, texture and lighting into your prompt. A style code does the same job with a number instead of a file, which is why people trade codes like recipe cards.

Midjourney Sref Code Library is a browsable gallery of style reference codes, the numbers people trade in place of image files. It is the largest and oldest library of its kind, run by Romain Simon, an entrepreneur who builds AI filmmaking tools at Melies. He started by collecting the best sref threads from X, then generated thousands of his own codes with --sref random to find styles nobody had posted yet.

The catalogue's main selling point is comparison. Most of the self-generated entries use the single word "portrait" as the prompt, so you see how each style transforms the same subject before you commit. Newer entries add more complex prompts to show range. Every code ships with a four-image preview, tags, and a copy button.

There is one thing it will not do. The site is a reference shelf, not an image generator. You still need a paid Midjourney subscription to render anything, and roughly 1,386 of the codes sit behind a one-time Premium unlock.

Getting Started

1. Open sref-midjourney.com in any browser. No account is needed to browse the public library.
2. Narrow the list with a tag such as Anime, Watercolor, Retro or Comic, or use the search field if you already know the style name.
3. Open a code you like, check the four sample images, then hit copy. The number goes straight to your clipboard.
4. Paste it at the end of a prompt in Midjourney: a stone cottage in a birch forest --sref 3193102811 --sw 300.
5. Raise or lower --sw between 0 and 1000 to decide how hard the style pushes against your own wording.
