AI-Optimized Image Quality Settings for Each Image

Our AI analyzes an image and sets the correct compression level just before visual artifacts appear. Combine it with an auto-format selection, and you’ve got the best compression-to-quality ratio for your project on the market.

Optimize original images with next-gen formats while reducing the image payload by up to 80% without compromising quality.

We support a wide range of image formats, including:

  • PNG

    A lossless image format that supports transparency and is ideal for images with simple graphics or text.

  • HEIC

    A newer image format with high-quality image compression and support for high dynamic range images.

  • WebP

    A modern image format designed for web use that provides better compression than JPEG or PNG.

  • GIF

    A format for short animations or graphics with a limited color palette.

  • TIFF

    A flexible image format that supports various color depths and compression.

  • AVIF

    A high-efficiency image format for high-quality image compression.

  • SVG

    A vector image format that can be scaled without losing quality and is ideal for logos and icons.

  • BMP

    A simple image format storing digital images as grids of pixels.

  • TGA

    An older image format commonly used in early computer games.

  • JPEG

    A popular image format used for photographs and other complex images.

  • PCX

    An older image format commonly used in early Microsoft Windows.

How Real-Time Image Processing API Works

Transform images on the fly without ever modifying the original file. Each time you apply an image processing operation, a new version of the image is created, while the original remains untouched. Plus, to ensure lightning-fast delivery to every part of the globe, all transformed image versions are cached on CDN nodes.

You can make it faster by using the Proxy, which allows you to apply image transformations without having to upload the image.

To make things even easier, we've implemented smart browser instructions. For instance, if you don't specify any image processing operations in the URL, our CDN will automatically instruct the browser to show images in-line and download other file types as attachments.


Multi-vendor CDN

No matter how big your CDN vendor is, sooner or later an outage will happen. We use multiple CDN providers at once. It expands our global presence and drastically reduces the probability of a major outage.

Before using Uploadcare, I just did all the image processing myself with scripts. You would give it the original image, and it would output five or six different versions. You would have to put them in different folders and maintain the folder structure and so on and so on. It was a nightmare. It’s a lot more work, and it’s not interesting work.


With Uploadcare's real-time Image Processing API and CDN, you can easily optimize and deliver high-quality images to your users, improving engagement, reducing bounce rates, and boosting conversions.
