Prompt Fixer — Free Image Prompt Optimizer
Fix and improve AI image generation prompts instantly
PromptFixer is a free tool that transforms raw, messy, or overly simple image generation prompts into clean, structured, high-quality prompts for AI image models.
Works with Midjourney, Stable Diffusion, DALL-E, Adobe Firefly, Leonardo AI, and any other text-to-image model. No account required.
How the prompt optimizer works
Paste your raw prompt and choose a fix mode. The engine cleans your text, detects scene type (portrait, cinematic, fantasy, product shot, architecture), resolves style conflicts like photorealistic vs anime, and adds contextually appropriate details — lighting, camera, composition — based on what your prompt actually needs.
Three fix modes
Strict mode cleans and reorders only, with no additions. Basic mode adds minimal scene-appropriate improvements. Enhanced mode applies full contextual enrichment including genre-specific lighting and atmosphere.
All processing is local and rule-based. No AI, no API calls, no data sent to any server. Deterministic and transparent — every change is explained.
