# Image Optimizer i3 ![icono i3](https://www.transparentedge.eu/wp-content/uploads/2026/01/inicio_i3.svg) ON-THE-FLY IMAGE OPTIMIZATION FROM THE EDGE IMAGE OPTIMIZATION: TRANSFORM, RESIZE, AND SERVE IMAGES QUICKLY Our i3 image optimizer transforms and serves your images on the fly from the ***edge*** and lets you take different versions of them based on your needs. It optimizes and processes your images, reducing the bandwidth you consume, increasing your bounce rate, and improving your positioning and user experience. [We help you](https://www.transparentedge.eu/en/contact/) ## WE MAKE DIFFICULT THINGS EASY FOR YOU When you set the dimensions in the tool, our i3 image optimizer performs a smart cropping to guarantee the image doesn’t exceed the set limits and reduce the computing time. Once you have set one dimension, the i3 automatically adjusts the rest of them to optimize the image. Plus, it includes strips that can be layered to compose images from an original. ## OPTIMIZE COSTS With the i3, you save bandwidth by serving images in more lightweight formats. Plus, you avoid having to manage image transformation servers and applications at your origin. You also save storage costs because only one image is saved as a source, and then used to generate whatever image you need on the edge. You reduce traffic costs by increasing cache storage on the edge and limiting requests to the origin. GAIN SPEED When you transform images on the edge, there are fewer requests returned to the origin, which eliminates latency. And serving images more quickly reduces the load time of sites. OPTIMIZE YOUR TIME Using our on-the-fly image transformation service means you no longer have to edit every image, saving you time. INCREASE CONTROL We send you logs in real time with information about how your image optimizations are working. Plus, you can purge instantaneously, invalidating content by tag. You can rest assured that you’ll always be delivering the most updated versions of images. EASY TO INTEGRATE Our i3 is a CDN product that’s easy to integrate with ours and with others on the market. Interoperability is simple thanks to our API. It’s quick and easy to install, and you can start using it right away with just a few changes to the configuration. COUNT ON US We are always standing by to help make things easier for you, no matter your technical level. When you need support, you’ll speak with our engineers directly in Spanish. And we are always quick to react. NO BILLING SURPRISES You pay a monthly commitment of images transformed, and if you go over that amount we’ll bill you for the excess.

You only need to store the original source file; variations are generated on demand when requested by the user. Your origin receives fewer requests, consumes less bandwidth, and you don’t need to maintain an image processing system in your infrastructure. Yes. i3 automatically converts between JPG, PNG, GIF, WebP, and AVIF. You can configure delivery to use the lightest format supported by the user’s browser (AVIF for Chrome, WebP for Safari, for example) without changing any code in your application. Image file sizes decrease and load times improve, directly impacting your Core Web Vitals. Yes, because these on-the-fly image transformations are performed at the edge, close to the user. You can add image optimization to your existing stack without migrating your entire content delivery infrastructure by placing Transparent Edge’s CDN in front. Another added benefit is that you’ll have a multi-CDN system. i3 uses the same fast invalidation system as the Transparent Edge platform. You can instantly purge transformed images by URL, regular expression, or tags. If you update an image at the source, you don’t have to wait for the TTL to expire: you trigger an invalidation, and the next request regenerates the image with the updated version from the source file. ## OTHER CDN PRODUCTS All our high-quality solutions are designed so you can start using them with little more than a few clicks, whatever your level of technical know-how. And if something goes wrong, you’ll always have personalized support and guidance. [Request information](https://www.transparentedge.eu/en/contact/) WAF Our next-generation WAF is an edge security service that protects websites and APIs from known application attacks. It analyzes traffic in real time, looking for malicious requests and making threats visible so they can be acted on immediately. It is an application firewall integrated with our CDN and compatible with other commercial CDNs. It does not require any installation on your infrastructure.

You will have the professional guidance of our team for the entire video conversion and delivery process. Once the transcoding has been done, you can publish the content anywhere you want. [More information](https://www.transparentedge.eu/en/edge-transcoding-en/) Mid-Tier It’s our origin shield. This second cache level lets you send requests to your back-end while facilitating security management at your origin. With fewer edge servers talking to the origin, it’s much simpler to establish and maintain filtering policies by IP. Online storage Replicated storage in CDN accessible via FTP, SFTP, and Rsync. INGESTION POINTS FOR LIVE STREAMING We provide an entry point for video signals in live video delivery events. Once the signal is ingested, we rewrap and transcode it, adapting it to be viewed correctly on end-user devices. LIVE STREAMING TRANSCODING We adapt video signals so they can be delivered with maximum quality to all devices. player With our HTML5 Player, we give your users a buffering-free experience via HLS adaptive streaming and DASH. --- Source: https://www.transparentedge.eu/en/content-delivery-cdn/i3/ Updated: 2026-05-22
