# API SDKs

> Official Convertly SDKs for JavaScript, TypeScript, and PHP. Convert, compress, process, transfer, and manage media from your application.

Build media workflows without assembling multipart requests, polling loops, or error handling by hand. Convertly API SDKs wrap the REST Media API for server-side applications, workers, and trusted automation.

## Choose the right SDK

| Goal                                                | Package                   | Start here                                 |
| --------------------------------------------------- | ------------------------- | ------------------------------------------ |
| Convert, compress, trim, transfer, or process files | `@convertly-sh/sdk`       | [JavaScript and TypeScript SDK](/docs/sdk) |
| Build server-side PHP or WordPress integrations     | `convertly/convertly-php` | [PHP SDK](/docs/php-sdk)                   |
| Deliver responsive images through the global CDN    | `@convertly-sh/image`     | [Image CDN SDKs](/docs/image-cdn/sdks)     |

<Note>
  API SDKs use a secret `cvly_...` API key and should run in a trusted environment. Image CDN SDKs use a CDN endpoint's public URL namespace and are safe to use in frontend code.
</Note>
