Flux 2 Pro I2I: AI Image Editor Online
Bottom line
Edits 1-8 images at once with an auto ratio that matches your source frame — 12 credits, 1K or 2K. Open the Image Edit tool, select Flux 2 Pro I2I, upload your image, and the exact credit cost appears before the edit runs.
Flux 2 Pro I2I is Black Forest Labs' multi-image editor: feed it between one and eight related images and it edits them with shared context, useful when a job needs consistent treatment across a set rather than one photo at a time. The aspect ratio list includes seven fixed options plus an auto setting that matches the output frame to your source image instead of forcing a crop or pad — the setting to reach for on targeted edits like object removal or recoloring, where the composition shouldn't shift.
It's the newer, second-generation Flux family (distinct from the original Kontext Pro/Max line, also on VdoBloom), and this I2I variant is edit-only — there's no from-scratch text-to-image mode here. Output resolution is 1K or 2K, prompts run 3 to 5,000 characters, and the price doesn't change between the two resolutions.
VdoBloom prices it at 12 credits per run, rates it 4.1, and applies its MODERATE content badge — standard provider filtering. The credit cost shows before you generate, and a failed job is refunded automatically.
What it costs on VdoBloom
Flux 2 Pro I2I runs a flat 12 credits regardless of resolution (1K or 2K) or how many of the up-to-8 input images you use. New accounts' 10 free credits don't quite cover one run — Flux Kontext Pro (7cr) or FLUX.2 [dev] (4cr) are the cheaper way to try Black Forest Labs' editing on the free balance first.
Choosing between Flux 2 Pro I2I and its Flux siblings
Within VdoBloom's Black Forest Labs lineup: FLUX.2 [dev] (4cr, up to 4 images, no ratio/resolution control) is the budget guided-edit tier; Flux Kontext Pro (7cr) and Kontext Max (10cr) are single-image instruction editors with a fixed 6-ratio menu; Flux 2 Pro I2I (12cr) is the multi-image option with auto framing and resolution control. The decision mostly comes down to how many source images the job needs and whether you need frame/resolution control — [dev] and Kontext don't offer either.
Common problems and how to avoid them
The auto aspect ratio exists specifically to stop editors from silently cropping or padding a source image during a targeted edit — if you've had an editor shift composition on what should have been a small local change, auto mode on Flux 2 Pro I2I is built to avoid exactly that. The 3-character prompt minimum is easy to trip on scripted or automated workflows; make sure the prompt field isn't sent empty or truncated. As with every model on VdoBloom, the credit cost is shown before you run the job and refunded automatically if it fails.
What creators use Flux 2 Pro I2I for
- Object removal, recoloring, or cleanup where auto mode has to keep the original framing untouched.
- Style-consistent edits across up to 8 related reference images processed in one job.
- 2K delivery for campaign or landing-page hero images in 16:9 or 3:2, with no resolution upcharge.

Frequently asked questions
How much does Flux 2 Pro I2I cost on VdoBloom?
12 credits per run, flat — 1K and 2K cost the same, and the price doesn't scale with how many of the 1-8 input images you use. The cost is quoted before you click Transform and refunded automatically if the job fails.
What do 10 free signup credits get me on Flux 2 Pro I2I?
Not quite one run — a new account's 10 free credits fall 2 short of the 12-credit cost. Flux Kontext Pro (7 credits) or FLUX.2 [dev] (4 credits) fit inside the free balance if you want to try a Black Forest Labs editor before topping up.
Is Flux 2 Pro I2I censored?
VdoBloom labels it MODERATE — standard content filtering, not the strict tier used on Nano Banana or GPT Image, nor the more permissive HOT tier some other editors here carry.
What does the "auto" aspect ratio do?
It sets the output dimensions to match your source image instead of forcing one of the seven fixed ratios. That keeps the original composition intact for targeted edits — object removal, recoloring, retouching — where cropping or padding the frame would be a regression.
How many images can Flux 2 Pro I2I edit in one job?
One to eight. A single image covers a straightforward edit; feeding several related images lets the model apply a consistent treatment across the set in one run rather than editing each separately.
Flux 2 Pro I2I vs Flux Kontext Pro — which one should I use?
Kontext Pro edits one image at a time across 6 fixed ratios for 7 credits, with Black Forest Labs' specific in-context preservation behavior. Flux 2 Pro I2I takes 1-8 images, adds an auto ratio and a 1K/2K resolution choice, for 12 credits. Use Kontext Pro for a single precise change; use Flux 2 Pro I2I when the job spans multiple images or needs 2K output.
Flux 2 Pro I2I vs FLUX.2 [dev] — what's the difference?
Both are Black Forest Labs' newer Flux 2 generation. FLUX.2 [dev] is the budget tier: up to 4 reference images, no aspect-ratio or resolution selector, for 4 credits. Flux 2 Pro I2I adds the auto/fixed ratio menu and 1K/2K resolution control, accepts up to 8 images, and costs 12 credits — pick Pro when you need frame control or higher output size, [dev] for quick guided edits on a budget.
Is there a minimum or maximum prompt length for Flux 2 Pro I2I?
Yes — prompts run from 3 to 5,000 characters. That floor is unusually strict among VdoBloom's image editors; a one- or two-word prompt will be rejected before the job runs.
Does 2K output cost more than 1K on Flux 2 Pro I2I?
No — unlike Riverflow 2.0 Pro, which adds a credit surcharge for its 4K tier, Flux 2 Pro I2I charges the same 12 credits at 1K and 2K. Resolution is a free choice here, not a pricing tier.
