How SwarmGen works
Build a template, fill in your data, get an image. No code required — or plug straight into the API for full automation.
Build your template
Open the editor and describe your design in plain English. AI Assist generates your template instantly. Adjust colours, fonts, layout, and fields by describing what you want — you will never need to look at a line of code. Or pick from a ready-made template in the gallery and customise it from there.
Add your content
Fill in the fields on the left — name, image, price, date, or whatever your template uses. The preview updates live so you can see exactly what the output will look like before you render.
Render and download
Hit the Render button. Your image or PDF is generated in seconds and downloads directly to your device. That is it. Come back any time, update your fields, and render again.
Common questions
What image formats does SwarmGen support?
PNG, JPG, and PDF. Set your preferred format per template, or override it per render request.
How long does a render take?
Most renders complete in under a second. Complex templates with external image assets may take a little longer while the browser fetches resources.
What dimensions can I render at?
Any width and height you set on the template. SwarmGen is designed for standard social media sizes (1080×1080, 1200×630, Stories) and office formats (A4, A5, certificates). The maximum canvas size is 8.7MP (width × height must not exceed 8,700,000 pixels).
Do I need to know HTML to use SwarmGen?
No. Using AI Assist, you can build and edit any template by describing what you want in plain English. You will never need to look at a single line of code. For those who want full control, Dev mode exposes the HTML, CSS, and JSON editors directly.
