SVG Converter API

About the SVG Converter API

SVG (Scalable Vector Graphics) is the standard for web vector graphics, but many platforms require raster formats. This API converts your SVG files to high-quality PNG, JPG, or WebP images with customizable dimensions.

What people use it for

Social Media Previews

To generate Open Graph preview cards, content management systems turn uploaded vector badges into JPG images via temporary download links.

Email Newsletter Graphics

When sending weekly digests, email marketing services render vector brand marks into PNG files so older mail clients display them properly.

E-Commerce Thumbnail Generation

Convert product design templates from raw vector files into WebP thumbnails before serving them to mobile shoppers in catalog feeds.

PDF Document Export

Report generation engines fetch converted raster PNGs to embed corporate vector charts into downloadable monthly audit documents.

Request parameters — POST /v1/svgconverter

Sent as JSON in the request body. Premium parameters are accepted on every plan but only take effect on plans that include them. Anything not listed here is dropped rather than passed through.

curl -X POST "https://api.apiverve.com/v1/svgconverter" \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"outputFormat":"png","quality":90,"maxWidth":1920,"maxHeight":1080}'

Authentication

Send your key in the x-api-key header. That is the only auth step — no token exchange, and no per-endpoint scope to configure.

Response — POST /v1/svgconverter

Every APIVerve endpoint returns the same three top-level keys, so one response handler covers your whole integration: status, error and data. Only data changes shape.

Response fields

Paths are relative to data. Premium fields are absent rather than zeroed on plans that do not include them, so check for presence instead of comparing to 0.

Response headers

Every response carries your balance, so your own code always knows where it stands without polling anything. All four are exposed to browsers through CORS.

Errors

Read the HTTP status first, then error for the specific reason. The body names the parameter that has to change.

What a call costs — 10 credits per call

Credits are shared across every APIVerve API — one balance, one key, one bill. Failed requests never count against it, so a rejected input costs nothing.

Calls are what the credits buy at this API's rate — spend them here, on any of the other APIs, or across both. Nothing is reserved per endpoint.

Zero-code embed — one snippet, no backend

Drop an interactive SVG Converter form onto any page. The widget calls the API for you, so no key ever appears in your markup and there is nothing to deploy.

Changelog — SVG Converter API

Every change to this endpoint, newest first. Breaking changes ship as a new version and the previous one keeps serving — response fields are added, never removed or retyped in place, so an integration written against v1 keeps working.
