  • Optimizing your images can speed up your site and improve the UX.
  • Lossless compression creates smaller images by removing unnecessary metadata, the image is rendered without degrading the image quality.

When you’re meticulously creating your digital footprint, we recommend specific formats for these common types of web images.

Next-generation image formats (e.g. WebP and AVIF) aim to achieve smaller image sizes while providing advanced visual features.

The following sections provide a brief overview of each of the image file types supported by web browsers. GIF is the only animated image format supported in all major web browsers and most image editors. GIFs support transparency and animation and can be highly compressed to reduce file size.

Because we must think about the pixel dimensions of monitors rather than the size of the object being printed.

WebP and JPEG XR have a number of advantages over the standard formats like PNG and JPEG – image size being the major advantage. A WebP image is 26% smaller than a PNG and up to 34% smaller than a JPEG. It delivers both lossless and lossy compression, and supports transparency just like a PNG. If you see a low-quality image with a repeating motion, it’s probably a GIF. Despite using lossless data compression, GIF supports only 256 colors, which results in poor image quality.

Getting rid of the original image and resizing your larger images can also be done with this plugin. So with more and more HiDPI displays nowadays, it can be good to find a happy medium. Say 2x or 3x your website’s column or div size, but still less than the original size.

You can perform a lossless compression on your desktop using tools such as Photoshop, FileOptimizer, or ImageOptim.

The Optimus plugin for WordPress, for example, automatically removes metadata and compresses the image without affecting their visual appearance.

To reduce page weight, consider converting your JPG images to lossy WebP and PNG images to lossless WebP format. The WebP format has been created by Google with the aim to replace GIF, PNG, and JPG with a more lightweight and flexible image format that has both a lossy and a lossless version. WebP was first announced on the Chromium blog in 2010, and its first stable version was released in 2018. Use JPG for photographic images and photo-realistic digital graphics that don’t include any text. While the standard HTML element doesn’t support compatibility fallbacks for images, the element does. XBM uses a snippet of C code to represent the contents of the image as an array of bytes.

An ICO file can contain multiple icons, and begins with a directory listing details about each. Each icon’s data can be either a BMP image without the file header, or a complete PNG image . If you use ICO files, you should use the BMP format, as support for PNG inside ICO files wasn’t added until Windows Vista and may not be well supported.

Like SVG files, EPS is actually a text-based document that outlines shapes and lines with code, rather than mapping pixels and colors. Giant file sizes without noticeable quality gains over formats like WebP, GIF, or PNG. Replace JPEG and PNG files to save bandwidth and speed up your site.

We’d recommend aiming for an image file size of no more than 500KB where possible. To help achieve this, reduce the size of your image down before saving & uploading . Anything below 1500 pixels wide could start to look a little blurry. Most native project image file types like PSD, XCF, and AI also support transparency.
