About imgproxy

What is imgproxy?

imgproxy is a self-hosted image processing server. It resizes and processes images on the fly from URL parameters. An open source version is free forever, and imgproxy Pro is a commercial license.

What imgproxy does

imgproxy is distributed as Docker images and Linux packages and runs on a hosting service or a local machine. Processing options are set in the URL. The features page lists JPEG, PNG, WebP, AVIF, JPEG XL, GIF, SVG, ICO, HEIC, BMP, TIFF, and animated GIF and WebP, plus resizing, crop, padding, rotating, and watermarking. URL signing, protection from image bombs, and authorization by an HTTP header are listed. You choose hosting to store the images and to run the imgproxy instances.

Who imgproxy is for

imgproxy is for developers who process images on their own servers. The open source version is under an MIT license. Pro is for teams that want the extra Pro features, production releases, and priority technical support.

How imgproxy works

Install imgproxy, upload images to storage, and request an image with processing parameters in the URL. The default number of workers per instance is twice the number of CPUs on the machine. You can tweak the number of workers per instance. Pro pricing uses the total number of workers across all instances. A 14-day Pro trial is requested from a form.
