# Bulk Generation
> Run one template across many products at once instead of generating images one by one.
Bulk Generation runs the same template across many products at once, instead of one by one.
## What it does
When you have a full catalog to shoot, generating one product at a time doesn't scale. Bulk Generation applies a single template — the same job, the same settings — to a whole batch of product images in one pass, so a catalog update takes minutes instead of days.
## Inputs
**Required**
* Product images — multiple product photos, uploaded together or pulled from a connected store. See [Product Images](/input-uploads) for shot guidelines.
**Optional**
* Reference image and model selection — applied uniformly across the batch if the chosen template supports them. See [Model Faces](/model-faces).
Connect **My Store** (Shopify or IKAS) to pull products directly into Bulk Generation and push finished images back once they're done — no manual export and re-upload.
## How to use it
Choose multiple product images to upload, or select products from your connected store feed.
Pick the single template to apply across the whole batch — every product in the run uses the same job.
Choose 1K, 2K, or 4K and the number of variations per product. This applies to every item in the batch.
Run the batch. Results save to your Library per product, and push back to My Store automatically if connected.
## Tips
Bulk Generation applies one template uniformly — products shot at different angles or lighting will carry those differences into the output. Standardize your inputs first.
Run 5-10 products first at 1K to confirm the template and resolution choice, then commit the full catalog at 2K or 4K.
If you're refreshing images regularly, a connected store feed saves you from re-uploading products every time.
