# Use cases: images and PDFs generated from templates

Each page below takes one kind of image a team makes again and again: the built-in templates for it, the platform's own rules with sources, and the requests that render one image or a whole spreadsheet.

- [Generate certificates automatically: PDF and image from one template](https://shareglint.com/en/use-cases/certificates): Issue course, event and award certificates from one template: one per completion over the API or hundreds from a CSV, as a PDF and a shareable image.
- [E-commerce product images from a template: share cards, sales and pins](https://shareglint.com/en/use-cases/ecommerce-product-images): Generate product share cards, sale and price-drop graphics, coupons and Pinterest pins from your catalogue — every product, every size, from one template.
- [Event graphics at scale: speaker cards, badges, tickets and agendas](https://shareglint.com/en/use-cases/event-graphics): Generate every graphic an event needs from templates and your registration data: speaker announcements, I'm-attending cards, badges, tickets and agendas.
- [Personalized images in email: one card per recipient](https://shareglint.com/en/use-cases/personalized-email-images): Put each recipient's name, offer or ticket into an email image: signed image URLs stored in a contact field, or a batch rendered before the send.
- [YouTube thumbnails from a template: size, API and bulk](https://shareglint.com/en/use-cases/youtube-thumbnails): Make YouTube thumbnails from an HTML template: the sizes YouTube asks for, one request per video or a whole series from a CSV, and the upload API.

## The same three ways in, whatever the image

- **One request**: POST /v1/images with a template and the values; the image URL comes back in about a second. The same values again return the same file, free.
- **A batch from a CSV**: POST /v1/batches with a CSV or a Google Sheet: every row and size is one image, all of them in one ZIP. Rows per batch by plan: Free 50, Starter 500, Pro 1,000, Scale 2,000, Business 5,000.
- **A signed URL**: An image address your own code computes from your account id and signing secret. It renders the first time someone opens it, which suits emails and pages.

Every built-in template renders in every size preset (og 1200×630, square 1080×1080, portrait 1080×1350, story 1080×1920, pinterest 1000×1500, youtube 1280×720) as PNG, JPEG, WebP, PDF; animated templates also as GIF, MP4.

## FAQ

### Do I have to design the templates myself?

No: 153 built-in templates cover thumbnails, events, products, certificates and more; copy one and change it, or write your own HTML and CSS.

### What does one image cost?

One render per image and size, and the same values again are free. The Free plan gives 100 renders a month with a watermark; Starter is $9 a month for 2,000 renders.

### Does it publish the images for me?

No. It returns image URLs; your scheduler, mailing tool or script publishes them. n8n, Make and AI assistants over MCP call the same API.
