Tips for Stable Diffusion
- Use (keyword:weight) syntax for emphasis — (masterpiece:1.2) boosts that quality tag; (motion blur:0.7) reduces it.
- Lead with quality boosters: masterpiece, best quality, highly detailed, sharp focus, 8k.
- Separate quality tags from subject tags: quality first, then subject, environment, lighting, style.
- Negative prompts are set in your UI (Automatic1111, ComfyUI, Forge) — focus the positive prompt on what you want.
- For character art, order matters: subject type, clothing, expression, pose, then environment.
- Keep prompts focused at 75–150 tokens — SDXL performs better with targeted prompts than bloated tag lists.

Free Stable Diffusion prompt generator
Upload a photo for a free image to Stable Diffusion prompt with weighted tags, quality boosters, and style references — formatted for SDXL, SD 1.5, or Pony Diffusion. Our free reverse prompt generator flow documents what's in your reference image so you can edit and reuse it in Automatic1111, ComfyUI, or Forge without starting from scratch.
The image-to-prompt output slots directly into the positive prompt field of your preferred SD interface. Negative prompts are not generated here — set these in your UI based on your specific checkpoint's known weaknesses. PromptMake focuses on maximizing the positive prompt's clarity and specificity.
Stable Diffusion prompt structure and weighted tags
A well-structured SD prompt leads with quality boosters (masterpiece, best quality, highly detailed, sharp focus, 8k), then moves to subject, environment, lighting, and style. Artist references (greg rutkowski, artgerm, wlop) and style tags (digital painting, concept art, illustration) anchor the aesthetic. Weighted emphasis — (golden hour:1.2), (bokeh:0.8) — fine-tunes element prominence without changing the overall composition.
For character art, prompt order matters: subject type and gender, clothing and accessories, expression and pose, then environment and background. Keep prompts focused — SDXL and newer models perform better with 75–150 token prompts than with bloated, tag-stuffed inputs. PromptMake follows correct tag ordering automatically when generating character, landscape, or product-focused prompts.

FAQ
Is this Stable Diffusion prompt generator free?
Yes — guests get 3 free image-to-prompt generations per day without signing up. Sign up for more. Stable Diffusion itself is free and open-source; run it locally via Automatic1111, ComfyUI, or Forge.
Can I upload a photo to extract a Stable Diffusion prompt?
Yes. Upload any reference image, select Stable Diffusion as the target model, and choose a goal mode. The output is formatted with weighted tags and quality boosters ready for the positive prompt field in your SD interface.
What is the difference between SDXL and SD 1.5 prompts?
SDXL handles longer, more natural prompts better than SD 1.5. SD 1.5 benefits more from tightly controlled tag lists and specific quality boosters. Both support weighted emphasis syntax. PromptMake outputs prompts that work well with both — keep quality tags at the start for SD 1.5 compatibility.
How do I handle negative prompts?
Negative prompts are handled in your UI (Automatic1111's negative prompt field, ComfyUI's negative conditioning node). PromptMake focuses on maximizing your positive prompt. Common negative prompt starters: 'blurry, lowres, watermark, text, ugly, deformed, extra limbs, bad anatomy.'
What are quality booster tags?
Quality booster tags (masterpiece, best quality, highly detailed, sharp focus, 8k uhd) are terms that SD models associate with high-quality training images. Adding them to the positive prompt nudges the model toward better output. Weight them at 1.1–1.3 for stronger effect: (masterpiece:1.2), (highly detailed:1.1).
