## Frequently asked questions

What is a generator?

A generator is a free maker for one specific document: a certificate, invoice, event badge, wedding invitation, or photo collage. You fill in a form, preview it live, and download a finished image. No design skills, no sign-up.

Are the generators really free?

Yes. Every generator here is free, with no account and no watermark. When you need to produce them in bulk, the same template runs through the Imejis API from $14.99/mo.

Can I generate these in bulk or from my own app?

Yes. Anything you make here by hand, you can also render from code. Design the template once, then generate one image per spreadsheet row, per form submission, or per API call. Each render comes back in under 2 seconds.

How are generators different from the free tools?

Generators build a finished, branded document from a form: a certificate, invoice, or badge. The free tools are utilities that change an existing image, like convert, crop, or watermark. Browse all 69 on the free tools page.
