ImageEngine supports all common image formats as input and output. It should be noted that the format, size, and quality of the origin images may affect the visual quality of the output image. It is recommended to use jpeg or png as origin formats.
Origin Image formats
Your origin image can be in any of the following formats:
- GIF *
- SVG **
* Rotation of animated GIFs is not supported.
** SVG files are not resized or converted, just optimized and compressed.
Note: the maximum file size of origin images is 5 MB. It is also good practice to publish images in high resolution to account for high PPI devices.
Output Image Formats
- JPEG XR
Note: AVIF is presently available by directive only.
Even if ImageEngine is built with image delivery in mind, ImageEngine supports any kind of content.
You can safely serve “non-image files” through ImageEngine too!
You may also create special settings for non-image content. For example, it may make sense to increase cache TTL.
If you plan to serve the entire website through ImageEngine, please reach out to our support team to plan the launch.
Optimization of non-image content
ImageEngine will do its best to optimize also text-based content. Any unoptimized non-image content will be checked for compatibility, and ImageEngine applies either Gzip or Brotli compression, dependent on browser support.
