​
Description

With this endpoint, you can create a new image by converting an existing image to a different format.

The supported image formats are jpeg, png, and webp.

  • JPEG (Joint Photographic Experts Group): A commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. JPEG compression significantly reduces the file size, but it can also reduce the image quality.
  • PNG (Portable Network Graphics): A raster-graphics file format that supports lossless data compression. PNG is often used for images that require transparency or when the image quality must be preserved without any loss.
  • WebP: A modern image format that provides superior lossless and lossy compression for images on the web. WebP images are smaller in size compared to JPEG and PNG, while maintaining similar or better image quality.

​
Request Parameters

The request path should contain the following parameters:

​
imageId
string
required

The ID of the image to convert.

​
Request Body

image_{string}

The unique identifier of the image. This identifier is used to reference the image in subsequent requests.

​
name
string

The name of the image. This name is provided when uploading the image and is the way the image is identified in your account. It is not unique, in fact, each transformation you make to an image will create a new image with the same name.

integer

The estimated size of the image in bytes. The size is an estimate and may not be exact since images can be compressed or optimized depending on the format and quality settings used during processing.

​
