What free image, video and data APIs does APIAny offer?
APIAny Free API is a catalog of deterministic image, video, GIF, and network-data tools you can try in the browser, then call with an API key.
Convert, inspect and compose media directly in your browser without a key. When your workflow is ready for automation, call the same API with an APIAny key.
No key for online use
Upload a file, choose settings and download the result from the browser Playground.
API key for integration
Programmatic requests use Bearer or X-API-Key authentication with documented limits.
Local processing stack
Media is processed by our Sharp and FFmpeg workers and is not sent to a paid AI model.

Which official references does this page cite?
The quotations below are from official API documentation that APIAny implements against.
The Fetch API provides an interface for fetching resources (including across the network).
The typical use case for this high speed Node.js module is to convert large images in common formats to smaller, web-friendly JPEG, PNG, WebP and AVIF images of varying dimensions.
The Images API provides several endpoints that let you generate images from text prompts or create edits of existing images.
