Adaptive image quality for flawless results

Our statistics algorithms ensure adaptive image quality. They analyze images faster than AI would, setting the correct compression level just before the appearance of visual artifacts. Automatic image format selection allows us to achieve the best compression‑to‑quality ratio on the market for your project.

You can also optimize original images with next-gen formats, 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.

Real-time image processing API and instant delivery

Transform images on the fly without altering the original file. Every time you apply an image processing operation, a new version of the image is delivered, while the original remains untouched. Additionally, to ensure lightning-fast delivery worldwide, all transformed image versions are cached on CDN nodes.

And you can make it even faster by using the Proxy, allowing you to apply image transformations without the need for uploading.

To make things even easier, we've implemented an automatic image format feature. If you specify any image processing operation, we will automatically select the most suitable image format supported by your browser.


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.
