Basic Features
Automatic Format Conversion
Automatically convert images to different formats like WebP for Chrome, Opera, Edge and Firefox, JPEG XR for IE 11, etc. Supported formates include JPG, PNG, WEBP, JPEG XR, JPEG 2000, HEIC
Automatic Quality Selection
Images are converted to different quality levels depending on structural similarity metrics with DSSIM and Butteraugli (Never waste time finding the perfect quality for your images ever again!)
Pixel Perfect Images for Different Devices and Networks
Images optimized and resized based on device size, screen resolution and the network using Client Hints.
Progressive Image Encoding
Progressive JPEGs are used to provide a better user experience under low bandwidth conditions.
Proper Metadata Management
Image metadata is properly managed without affecting colour profiles (16% of the image size contains unnecessary information that can be safely removed)
Optimise SVGs
SVGs are losslessy optimised to reduce file size, while preserving visual quality.
Dynamic resizing of images
Images are automatically resized based on the device width and DPR (device pixel ratio)
Different optimisation modes for easy optimisation
Choose between different optimisation modes to control the level of optimisations for each of your images. These can be controlled on a per URL level or for groups of images using our page rules.
Auto rotate based on EXIF data
Images are automatically rotated to the right orientation and the orientation metadata is stripped out so that they consistently render across different browsers.
Advanced Features
Intelligent Chroma Subsampling
Images are classified as photographs, drawings, images which have text in them, etc. using machine learning and the right chroma subsampling level is applied to each of them.
Other Advanced Compression Techniques
Near lossless compression for PNG and JPEG using advanced compression algorithms like ZopfliPNG and Guetzli.
Optimise GIFs
GIFs are automatically converted to better animated formats like animated WebP, animated PNG and even videos for much smaller file sizes.
Optimise images depending on network speeds
Images are more aggressively optimised when requested from a slow network leading to a faster browsing experience for users on low bandwidth conditions.
Detect faces in images
Images can be automatically cropped and resized based on faces detected in images.

Brotli Compression
For modern evergreen browsers Brotli compression leads to 39% smaller HTML files, 26% smaller JS files, 27% smaller CSS files.
Zopfli Compression
For older browsers which don't support Brotli, assets are encoded with Zopfli encoding which leads to better compression than GZIP.
Automatic Font Optimization
Fonts are converted to much more modern formats like WOFF2 (when supported)
Automatic Transpilation
ES6+ code is automatically transpiled for older browser ensuring maximum compatibility and directly delivered to modern browsers leading to smaller code sizes and faster parse times.
Optimising JavaScript Bundles
Ship lesser bytes down the wire by using advanced minification and dead code removal techniques.
Better Digital Experience with Smaller Web Assets
39% smaller HTML files, 26% smaller JS files and 27% smaller CSS files. You can create an immersive web experience without worrying about loading time.
Improve Indexation, Traffic and Ranking
Fast loading pages can improve indexation as Googlebot spends its time more efficiently when crawling a fast-loading site.
Helps prioritize content above the fold (top portion of the page)
Load all JavaScript in a page asynchronously. Detect and insert the CSS required to render the top of the page automatically.
Faster parse and execution time
JS files are optimized for every browser engine heuristics, even older browser versions.
Optimize Videos
Features
Automatically Convert to Different Resolutions
Videos are encoded in different resolutions depending on the resolution of the device requesting the video.
Automatically Convert to Different Formats
Videos are automatically encoded in different formats depending on the capabilities of the browser requesting the video. Supported formats include MP4, WebM, etc.
Support Adaptive Streaming
Support adaptive streaming via HLS and MPEG-DASH
Support Multiple CDNs based on Latency on Client
Using our Multi-CDN, the fastest CDN is automatically chosen by analysing the real-time latency information from users across the world.
