Image resizing and compression
In order to load fast on any device around the World, images must be resized, cropped and compressed. No need to push a 10MP image to deliver a thumbnail on the end-user device. Filerobot will manipulate and transform your images to be optimized for web delivery and save you hours in image management.
Filerobot's image manipulation and transformation features rely on Cloudimage, the European leader in Cloud image optimization and delivery. Cloudimage will continue to run as a standalone service and all its features are integrated into Filerobot.
If you do not need storage of your origin (master) images and Digital Asset Management but just on-the-fly image transformation and CDN delivery, check-out Cloudimage. Cloudimage will pull your images from your origin hosting (web server, S3 bucket, ...), cache, compress and deliver them over CDN. If you want to transform and accelerate both images stored in Filerobot and images hosted by yourself, then use Filerobot and continue reading.
We have documented the most common resizing functions here. Cloudimage supports many more, but we want to focus on what is really necessary for you to get started. If you have any request for undocumented features, contact us and we will help you out!
The basics
Everything starts with the basic URL format of a Filerobot URL:
//token.filerobot.com/folder/filename?operations&filters
| token | Your Filerobot token. |
| folder/filename | Here you can use the full path to the image in your Filerobot storage, e.g. demo/part2/image.jpg. |
| operations | Image manipulation operations like width, height, crop, fit, rotate, trim. For a full list, see image resizing. |
| filters | Use filters like contrast, pixellate, blur, greyscale and sharpen to apply different effects on your image. All filters can be found in the filter section. |
Cloudimage's resizing servers, located in three data centres worldwide (Canada, France, and Singapore) will download your original image from your container, transform it based on the operation and filter parameters, and finally, display it on your website or mobile app through a rocket fast CDN.
Examples
Please refer to the full list of options here: resizing operations, image filters, watermarking, compression and image formats.
All these images are delivered by default over the 200 Points of Presence (PoPs) of our CDN and will load rocket fast worldwide. The purpose of this documentation is to explain all available parameters.
