FLUX.2 Image Editor — klein 4B & 9B, No API Key
FREE CREDITS MONTHLY NO CARD NEEDED
Reference-based image editing with FLUX.2 [klein] right in your browser — upload an image, describe the change, generate. Pick 4B for speed or 9B for detail. Switch to Nano Banana 2 or Qwen with one click.
“Change from electric to fire monkey” “Change from electric to water monkey”
Describe the change — everything else stays put
Write the edit in plain English and the model changes exactly that. Identity is locked by default: face, outfit, colors and rendering style carry over untouched, so a wardrobe swap never becomes a new character.
Four different edits in one run
Multi mode takes one image and four quick briefs and returns four full-size results in a single generation — same character in every one. Write your own briefs or roll a random set of poses, emotes and views.

Or turn one image into a full turnaround
The turnaround pipeline renders a full-body T-pose from your upload first, then rotates that render into right, back and left views — four consistent full-size images plus a free combined sheet.
FLUX.2 image editing — FAQ
What is FLUX.2 image editing?
FLUX.2 [klein] from Black Forest Labs unifies image generation and editing in one model: upload a reference image, describe the change in plain English, and it renders an edited version. It's fast — the distilled klein models finish in a few seconds.
What's the difference between FLUX 4B and FLUX 9B?
Both are FLUX.2 [klein] models. 4B is the fast, lightweight option — great for quick iterations. 9B is larger and slower but produces higher-fidelity detail. Switch between them in the Model selector; your image and prompt stay put.
Do I need ComfyUI, a GPU, or an API key to run FLUX.2 editing?
No. Everything runs server-side — open the page, upload an image, pick FLUX 4B or 9B, describe the edit, and generate. No workflow wiring, no local GPU, no API token.
What edits work best on FLUX.2 klein?
Reference-based transforms: restyling a character, changing outfits or props, adding elements, and style transfer from your uploaded image. Describe what you DO want in concrete terms — FLUX ignores negative prompts.
FLUX.2 vs Nano Banana 2 vs Qwen-Image-Edit-2511 — which should I pick?
FLUX.2 klein is the fast iterator. Nano Banana 2 (Google) leans photoreal and handles scenes/lighting beautifully. Qwen-Image-Edit-2511 is the identity-lock specialist for keeping a character exactly recognizable. Same tool — switch models any time.
