Dynamic Responsive Images

Responsive images yield crucial performance improvements, but require creating multiple versions of each image and sending users the one that best suits their viewing context.

Cloudinary simplifies responsive images by dynamically adapting image properties — dimensions, crop, format, quality — on-the-fly and delivering the optimal version based on the content and viewing context.

Upload Once - Deliver Anywhere

Upload a single high-resolution version of any image and dynamically manipulate the image, on-the-fly, to fit the resolution, viewport and layout for any device.

Automatic Resolution Switching

Dynamically scale an image’s resolution to optimize it for each user’s device resolution and viewport dimensions, without wasting bandwidth.

Automatic Art-Directed Cropping

Detect an image’s region of interest and crop it to fit the layout on any device, without losing focus on the important area.

Automatic Pixel Density Detection

Determine the pixel density of the viewing device and manipulate the image to serve the most appropriate version.

Determine Image-Specific Breakpoints

Responsive design requires scaled-down versions of each image to cover different device and layout dimensions. But how many versions do you need?

Balance the trade-off between dimensions and bandwidth reduction  by automatically selecting the optimal responsive image breakpoints.

Based on the calculated breakpoints, HTML5 markup code is created using a code sample that combines the different aspect ratios and their breakpoints into a single responsive HTML solution.

Automate Resource Selection With HTTP Client Hints

Devices used to access the web have different display capabilities. Serve images that are optimized to meet various device requirements.

Cloudinary selects the optimal resource by using Client Hints to determine the device pixel ratio and the available image width of the viewing device.

With this information, Cloudinary selects or dynamically generates the appropriate size of the requested image.

Each image can be tailored to a user’s specific requirements, ensuring a visually seamless experience while improving performance.
