Is JPEG-XL worse than AVIF on non-photographic images?

In comparison to AVIF, JPEG-XL typically provides higher versatility and efficiency when dealing with non-photographic pictures.

It is a good option for a variety of image kinds, including graphics and diagrams, thanks to its lossless mode, progressive encoding, and effective compression techniques. While AVIF is effective for photographic images, its major concentration on photographs and the lack of standardized lossless support may prevent it from consistently delivering the best results for non-photographic information.

Let’s talk about it in depth:

1. Effectiveness with Non-Photographic Images

JPEG-XL

JPEG-XL is made to be a flexible format that can handle different picture formats, including non-photographic ones. To achieve great compression efficiency, it combines methods including color quantization, predictive coding, and spatially variable filtering. JPEG-XL can frequently offer effective compression when non-photographic images include significant sections of uniform color or gradients.

AVIF

Since it is primarily designed for photographic images, AVIF frequently delivers remarkable results in that area. Its performance with non-photographic pictures can, however, be inconsistent. As AVIF’s optimization is primarily focused on photographic content, it occasionally produces larger files than anticipated, especially with basic graphics and solid colors.

2. Lossless option

JPEG-XL

JPEG-XL has a lossless compression option that is notably useful for maintaining the quality of non-photographic images, especially when accuracy and detail retention are important considerations. It works nicely for graphics and diagrams because of this characteristic.

AVIF

Unlike JPEG-XL, AVIF does not have a standardized lossless mode. Although it has a lossless mode, it might not be widely supported and its compression efficiency might not be as good as JPEG-XL’s.

3. Progressive encoding

JPEG-XL

JPEG-XL allows progressive encoding, which enables images to be shown at lower resolutions as they load. This feature provides quicker initial rendering in web and mobile applications, which can be advantageous for non-photographic images.

AVIF

Similar to JPEG-XL, AVIF also enables progressive encoding, which is useful for non-photographic images. It makes it possible for online and mobile applications to display images more quickly when they first load.

4. Adoption

JPEG-XL

JPEG-XL is becoming more widely used, but it may not be as widely accepted as older formats like JPEG. However, it is anticipated that support will extend more broadly in time.

AVIF

As more online browsers and image editing programs implement AVIF, consumers will find it easier to use. Its acceptance may, however, lag behind those of well-known formats like JPEG and PNG.

Note

It’s important to consider the distinctive qualities of your photographs while choosing between JPEG-XL and AVIF for non-photographic images. Consider the following:

1. Image Content

JPEG-XL’s adaptive encoding methods, which guarantee the preservation of clarity and fine details, may be more advantageous for non-photographic images with text, graphics, or sharp contours.

2. Colour Diversity

The JPEG-XL color space modifications can be useful for keeping accurate color fidelity when your non-photographic images have a diverse color palette.

3. Tests to be Run

It is advice to use your own collection of non-photographic picture samples to run thorough tests. You will be able to decide which format best meets your unique usage requirements by balancing image quality and compression effectiveness.
