Single-image AI generation is impressive. Batch generation is transformative.
The economics of ecommerce photography change entirely when you move from processing one product at a time to processing an entire catalogue simultaneously:
| Metric | Single-image AI | Batch AI (Sellable) |
|---|---|---|
| Products per session | 1 | 50–500+ |
| Time per product | 5–10 min | ~30 seconds |
| Time for 100 products | 8–16 hours | ~1 hour |
| Consistency | Manual per image | Automatic across all |
For brands with catalogues over 30 SKUs, the difference between single-image and batch processing is the difference between AI photography being useful and being operational.
When batch generation is essential:
- Launching a new product range (20+ SKUs going live simultaneously)
- Rebranding or refreshing your entire store's image style
- Expanding to Amazon and needing compliant white backgrounds for every ASIN
- Seasonal catalogue refreshes
- Migrating from a marketplace to your own Shopify store
Batch output quality is directly tied to input consistency. Before uploading a batch, ensure your source photos are standardised:
Source photo batch checklist:
- [ ] All products photographed against the same background colour (white preferred)
- [ ] Consistent lighting across all source photos (shoot in the same location, same time of day, or use the same artificial lighting setup)
- [ ] All products photographed from the same angle and distance
- [ ] All source photos at similar resolution (within 20% of each other)
- [ ] Products fill 70–80% of each source frame
- [ ] All photos in the same file format (JPG preferred for batch)
- [ ] Files named clearly (SKU or product name in the filename)
The more consistent your source photos, the more consistent your batch output. Even small variations in source lighting or background colour can create noticeable differences across the output set.
Step 1: Organise and standardise source photos
Create a folder with all source photos standardised to the same format, resolution, and framing approach. Rename files to match your product SKUs or catalogue IDs.
Step 2: Upload to Sellable's batch interface
Upload all source photos simultaneously. Sellable's batch interface accepts multiple files in a single upload session.
Step 3: Configure generation settings
Apply generation settings to the entire batch:
- Scene type (Studio White, Lifestyle, Detail)
- Scene description / prompt (applies uniformly to all products)
- Output resolution (select 4K for all marketplace and ad use)
- Aspect ratio (1:1 for Shopify/Amazon, 9:16 for social variants)
Step 4: Initiate batch generation
Run the batch. Sellable processes all products in parallel — generation time scales approximately with the number of products rather than multiplying per-product time.
Step 5: Review and download
Review the output set for any products that need regeneration (occasional edge cases with complex materials). Download the full batch as a ZIP or to a designated folder.
Step 6: Upload to platforms
Use Shopify's bulk product import or Amazon's feed tools to upload generated images to your catalogue at scale.
Sellable turns a single product photo into studio-quality images, cinematic video, and on-brand campaigns — in under 60 seconds.
Get started free →Sellable's batch processing is the feature that separates it from single-image tools like Photoroom and Pebblely. It's built for the operational reality of growing ecommerce brands: catalogues of 50, 100, 500 products that all need professional images on a realistic timeline.
The Sellable batch workflow is how brands that would otherwise spend months and tens of thousands of dollars on photography can reimage their entire catalogue in a day.
*"We acquired a brand with 340 products that had inconsistent, low-quality photography. Sellable batch processing let us re-image the entire catalogue in two days. The brand looks like a completely different company."* — Jason T., ecommerce brand aggregator
*"Every time we do a seasonal refresh, I batch generate new lifestyle images for our 80 hero products. Takes an afternoon with Sellable. Used to take three weeks with a photographer."* — Lena K., Shopify brand manager
*"I manage photography for four separate Shopify stores. Without batch generation, this job wouldn't exist — there aren't enough hours. Sellable makes it possible."* — Raj P., ecommerce operations manager

Batch generation at scale requires a systematic QC process to catch exceptions before they go live:
Exception categories to check in batch output:
- Complex reflective surfaces (mirrors, chrome, highly polished metal) — may require individual regeneration
- Very dark products on dark backgrounds — check edge accuracy
- Products with fine details (jewellery chains, thin typography) — verify label legibility
- Transparent or partially transparent packaging — verify product outline accuracy
Efficient batch QC process:
1. Generate all images in batch
2. Do a rapid visual scan (3–5 seconds per image) to flag obvious issues
3. Regenerate flagged images individually with adjusted settings
4. Perform final check on any regenerated images
5. Export clean set
For a 100-product batch, this QC process typically takes 30–60 minutes — still dramatically faster than any alternative approach.
How many products can I process in a single Sellable batch?
Sellable's batch processing scales to hundreds of products simultaneously. For very large catalogues (1,000+ products), run in multiple batches of 200–300 for easier QC management.
Does batch generation reduce image quality compared to single-image generation?
No — Sellable uses the same generation model for batch and single-image processing. Output quality is identical.
How do I ensure consistency across a large batch?
Use the same prompt and settings for all products in a batch. Natural AI variation will produce slightly different compositions for each product, but the visual style (lighting, surface, mood) will be consistent.
Can I apply different scenes to different products in the same batch?
Yes — you can tag products in different categories with different scene settings before initiating the batch. This is useful for multi-category catalogues where skincare products need different scenes from supplements, for example.
What's the best file organisation for a large batch upload?
Name source files with your product SKU (e.g., SKU-001.jpg, SKU-002.jpg). This makes matching generated output to the correct product listing trivial, especially when uploading to Shopify or Amazon via product feed.
