Flux 3 Image Edit: edit one photo or combine up to ten
Flux 3 Image Edit changes a photo from a sentence and can blend up to ten pictures, named by their order. Three recipes, the settings that matter and one limit.
Black Forest Labs built Flux 3 Image Edit around one habit that sets it apart from most editors in the catalog: you talk about your pictures by number. Upload a portrait and a jacket, and the prompt says "put the jacket from image 2 on the person in image 1". The order you upload in is the order the model reads. Once that clicks, it becomes a compositing tool as much as an editor, because it accepts up to ten pictures in one run.
This post is three recipes, then the settings, then the one thing to watch. If you are new to edit prompts in general, our edit prompt guide is the gentler start.
Recipe 1: change one object, keep everything else
The example on the model page is a product redesign: a woman holds a perfume bottle, and only the bottle changes. The prompt is long, and every sentence earns its place. It says what changes, down to the material and the lettering, then lists what must not move.
Redesign only the perfume bottle she is holding. Change it to deep emerald-green translucent glass with a brushed gold cap. Replace the label text with "NOCTURNE" in elegant gold lettering. Keep the bottle's original shape, size, position and orientation. Preserve the woman's exact face, expression, hairstyle, clothing, jewelry, pose and finger placement. Keep the background and composition unchanged. Update reflections and the subtle light through the glass to match the new materials.Notice it writes the label text in quotes. Lettering on packaging is part of what this family is known for, so a renamed product mock-up is a fair job to give it.
Recipe 2: one subject, a new place
Place the ceramic teapot from image 1 on the wooden kitchen counter in image 2, beside the window, in the soft morning light of image 2. Keep the teapot's glaze, shape and spout unchanged. Add a faint reflection of the teapot on the counter.Here the aspect ratio matters. Leave it empty and the output follows the first image, so the teapot packshot would decide the frame of a kitchen scene. Either upload the room first and refer to it as image 1, or pick a ratio yourself from the list, which runs from very wide to very tall.
Recipe 3: a set built from parts
Create a flat-lay on the linen tablecloth from image 1: the notebook from image 2 in the centre, the fountain pen from image 3 across it, and the coffee cup from image 4 in the top right corner. Even top-down daylight, soft shadows. Keep each object's colours and details as in its photo.This is where the ten-picture limit pays off: a mood board, a product bundle or a styled scene from separate photos, without a manual cut-and-paste. Our post on reference images has more on keeping a look consistent across a set.
The settings that matter
- Resolution comes in three steps, the smallest by default. Higher steps cost more and the top one can take several minutes. Get the edit right at the default, then re-run the keeper once at the step you need.
- Output format (Advanced): JPEG by default, PNG if you plan to edit the result again.
- Prompt expansion (Advanced, off by default) rewrites your prompt in more detail while keeping its intent and the roles of each image. Useful for a one-line idea; leave it off when you wrote a careful prompt like Recipe 1, since you already said exactly what you want.
Who should pick it
Pick it when you want to say which picture does what: compositing several products, putting an outfit from one photo on a person in another, or a label change where the lettering matters. If you only ever upload one photo and talk about it in plain words, other editors such as Nano Banana 2.1 Edit work just as well. Its text-only sibling is covered in our Flux 3 Text-to-Image guide.
What to watch
It edits by regenerating the picture, not by masking. There is no brush to protect a region, so the "keep ... unchanged" sentences are your only guard, and small details near the change (a ring next to the bottle, a word on a sign behind) can come back slightly redrawn. Compare the result with the original at full size. Edits that touch real people's faces or bodies may also be refused by moderation; a refused or failed render costs nothing. Edit only pictures you have the right to use, in the studio, where the Generate button shows the price for your settings.
Questions
How many images can Flux 3 Image Edit take?
One to ten in a single run. Refer to them by their upload order: image 1, image 2 and so on.
Which aspect ratio will the result have?
If you leave the ratio empty, it matches the first image you uploaded. Pick one from the list to change it.
Does a higher resolution cost more?
Yes. The price follows the resolution step you choose and shows on the Generate button before you run. A failed render is refunded.
