Image Optimization
CacheFly's Smart Image Optimization service is an efficient and secure solution for image processing, enabling dynamic transformation and optimization of your images. Performance and user experience can thus be enhanced as the images are transmitted to users via your CacheFly service.
The image optimization functionality is split into three categories:
Advanced Features offer the dual advantage of refining content distribution network (CDN) behavior and optimizing interactions with clients requesting images, thus providing a sophisticated layer of customization and efficiency.
Image Operations provide precise control over image presentation, ensuring that each image is displayed exactly as intended, enhancing both aesthetic appeal and functional alignment within your digital content.
Image Filters are applied after Image Operations and serve to adjust the image's aesthetic properties without altering its visible dimensions.
These can be invoked through two different methods:
For the most commonly used functionality, predefined transforms provide simplified, consistent image processing by defining uniform transformations in the configuration, triggered via specific paths for a library of images.
For all functionality, dynamic transforms offer the highest level of flexibility for real-time image processing and content adjustment through an URL syntax, requiring your application to define transformations.
