BulkImagen

BulkImagen is built around a simple idea: most AI image tools are designed for exploring one idea at a time, while real production work needs dozens or hundreds of images that stay consistent. Instead of prompting repeatedly, you bring a list — one prompt per line, or a .csv/.xls/.xlsx file with a prompt column — and BulkImagen runs every line as its own prompt using the same model, aspect ratio, resolution and images-per-combo settings. The result arrives as one ZIP archive plus a CSV manifest telling you which generated file came from which prompt.

Alongside the core generator it ships a large library of task-specific generators (product photography, ad creatives, social posts, storyboards, game assets, logos, avatars, coloring pages, affirmation cards and more) plus a set of free browser-based utilities like a bulk image resizer, cropper, compressor and format converter. Optional reference images let you keep a product or character consistent across the whole batch, and the same batches can be triggered from code through an API.

Pricing is prepaid credits rather than a subscription: you buy a credit bundle and spend it only on images that are actually produced. Credit cost varies by model, and cheaper models such as FLUX are significantly less expensive per image than frontier models. Output is watermark-free and credits do not expire. Because this is a third-party platform, model names such as GPT Image, Nano Banana, Seedream and FLUX refer to the underlying engines the service routes to, not to official offerings from those vendors.
