Turn a written brief into an image, or upload photos and describe what to change with FLUX.3 Klein. Choose the composition, output size and format in one workspace; sign in and check the displayed credit cost before creating.
FLUX.3 Klein is a Black Forest Labs image model for text-to-image generation and reference-based editing. On FireRed Image Edit, start from a description or up to 10 images and request one PNG or JPEG at 1K, 2K or 4K. Use it for product scenes, visual concepts and photo variations, then review the output before sharing. This page serves the Klein image model, not FLUX 3 video or audio generation.
Prepare clear inputs, choose the right output and review the details that matter for your project.
Describe the main subject, setting, light and framing before adding style details. For a product concept, specify its material and the space around it. Start with one clear composition rather than several conflicting scenes; you can refine the next attempt after reviewing the first image.
Upload a sharp photo and name both the change and what should stay: for example, replace the background while keeping the product shape and viewpoint. The model can also change unintended details, so compare faces, labels, edges and proportions with the original before using the edit.
Use JPG, PNG or WEBP references of up to 10 MB each. Explain each image's role, such as the subject, setting or colour direction, and avoid contradictory views. Ten is the upload limit, not a guarantee that every identity or detail will be preserved; fewer well-chosen images may make your request clearer.
Use 1:1 for square placements, 4:3 or 3:2 for landscape layouts, 3:4 or 2:3 for portraits, and 16:9 or 9:16 for wide or vertical compositions. Auto uses a square for text-only generation and lets an image edit follow its references. Describe where the subject should sit if you need room for later typography.
Choose the output resolution before generating and select PNG or JPEG. One request returns one image. Higher resolution can help with larger placements but does not repair incorrect text, anatomy or product detail; verify the result at full size. The actual pixel dimensions depend on the selected resolution and aspect ratio.
Keep any requested wording short and clearly separated from the rest of the description. After generation, read every label and check hands, reflections, repeated objects and small patterns. For a finished poster or product label, add precise typography in your design editor rather than assuming generated text is error-free.
Try a tabletop product scene, a seasonal background or a consistent colour direction for a campaign concept. Keep the reference product visible and change one major element at a time. Compare the generated silhouette, packaging and logos with your source; a visually appealing concept is not proof of an exact catalogue match or permission to use a brand.
Sign in, confirm your balance and the credit estimate, then submit your request. Once the image is ready, inspect it and use the result's download control. Open the saved file before handing it off for a website, presentation or further editing. Check rights to your inputs and applicable service and model terms before publishing.
FLUX.3 Klein Image Generator FAQ
Generate an image from text or upload references for a new version of a photo. Product scenes, composition studies and background edits are useful starting points. This workspace uses the FLUX.3 Klein image model; it does not generate FLUX 3 video, sound or robot actions.
Select FLUX.3 Klein and upload a photo in the image input. Describe what to change and what to preserve, then choose the output settings and generate. A text-only request needs no reference image. Compare the edited result with the source, particularly faces, lettering and product shape.
You can add up to 10 reference images in JPG, PNG or WEBP, with a maximum of 10 MB per image. Use clear, relevant images and describe their roles. Adding more references does not guarantee faithful preservation of every detail.
The generator offers 1K, 2K and 4K, with PNG or JPEG output. Ratios are auto, 1:1, 4:3, 3:4, 16:9, 9:16, 3:2 and 2:3. Auto becomes 1:1 for text-only generation; editing passes the automatic ratio setting to the image model. Each request produces one image, not a batch.
Generation on FireRed Image Edit requires an account and credits. Check the displayed estimate before submitting; resolution and whether you provide reference images affect the cost. Any available credits are shown in your account. This page does not promise unlimited free use or a fixed generation time.
No. This page selects FLUX.3 Klein for image generation and editing. FLUX.2 has its own image-model page, and FLUX 3 video is a different workflow. Features described for the wider FLUX family, such as video or box-based editing, are not automatically available in this workspace.
Reference images and explicit instructions help communicate your intent, but details can change. Check identity, anatomy, logos, spelling and any important measurements. If exact brand artwork or typography is required, finish and verify those elements in an appropriate image editor.
When generation finishes, review the image and use the download control on the result. PNG or JPEG can be opened in common design tools. Commercial use depends on your rights to the inputs and the applicable model and service terms; there is no blanket permission for third-party faces, artwork or trademarks.
