Bulk generation

Bulk mockup generator for print-on-demand sellers

The work in mockups is not the design. It is the multiplication: every design has to be exported against every color you sell, and adding one design adds the whole column again. This does the multiplication for you.

The arithmetic

What one design actually costs you

These are the real color counts in this catalogue, not an illustration.

The last column is the point. However far the other numbers grow, the amount of work you do stays where it is.

How the batch runs

Built to finish, not to look fast

0 uploads

Rendered on your machine

Your designs never leave your computer. There is no upload, no server queue and no waiting behind anyone else's job.

1 file at a time

Streamed straight to disk

Each finished mockup is written out before the next starts, so memory stays flat and a few gigabytes of PNGs complete without taking the tab down.

4096px

No upscaling anywhere

Every file renders at its mockup's native size, up to 4096 × 4096. The detail in the output is real detail.

What you get back

A ZIP you can upload without renaming anything

  • One folder per design
  • Every file named by its color
  • The listing thumbnail marked, so you know what to upload first
  • PNG, WebP or JPEG, your choice per batch
  • Optional color-name label stamped on the image
  • Optional logo or watermark in the same spot across the run

Catalogue

325 garment colors across 11 mockup styles, with swatches sampled from the real photographs rather than from a brand color chart.

FAQ

Bulk generation questions

What counts as bulk?
Every design you have loaded, rendered against every color you have ticked. Three designs across Comfort Colors 1717's full range is 1284 files from one click, and nothing about that run is slower per file than doing one.
Will a large batch crash my browser?
Renders run one at a time and each finished file is streamed straight to disk rather than held in memory, which is what stops a multi-gigabyte run from taking the tab down. It is the difference between writing files and accumulating them.
Do my designs get uploaded anywhere?
No. Rendering happens in your browser using your own machine, and the ZIP is written directly to your disk. There is no upload step and no queue to wait in.
Can each design have a different placement?
Yes. Share one placement across everything, or give any design its own placement, its own color selection and its own listing thumbnail.
What formats can I export?
Lossless PNG for listings, lossless WebP at roughly half the file size, or quality-95 JPEG when size matters most.
