Convert PNG to WebP API - ApyHub

About

This Utility API provides a powerful PNG to WebP converter, allowing developers to convert PNG files to WebP programmatically with ease. The WebP image format is a modern alternative to Portable Network Graphic (PNG), offering a format that uses lossless compression while delivering smaller file sizes and maintaining high image quality.
By integrating this API, you can efficiently transform image formats for web delivery, improving page speed and optimizing Core Web Vitals. It’s ideal for web developers, front-end engineers, and e-commerce platforms looking to automate the process, or even batch convert PNG to WebP online within their own workflows.
The API ensures that each converted WebP retains excellent image quality, reducing bandwidth consumption and improving user experience across devices.
Try the API in the playground to see how quickly and efficiently you can optimize and modernize your images with ApyHub.

All API requests to ApyHub services need to be authenticated. Currently we support tokens or basic authentication mechanisms. You can generate and view your existing credentials from your workspace settings (on the left side of the navbar) and go to “API Keys".
Points to note:
  • Credential secrets are generated on the fly and are not stored in plain text, so on generating a credential please save the secrets somewhere safe.
  • Use the apy-token as the header parameter to pass the token.
  • Use the Authorization header to send the basic authentication credentials.
