The JPEG XL Viewer Chrome extension enables seamless viewing of JPEG XL images, a next-generation image format developed by Google and Cloudinary. It supports both lossy and lossless encodings, delivering smaller image sizes without sacrificing quality compared to existing browser formats.

Since JPEG XL is a new and not yet widely supported format, this extension allows web pages to load JPEG XL images normally without native browser support. Perfect for developers, photographers, and web users, JPEG XL Viewer brings cutting-edge image technology to your browser today.

User reviews

The JPEG XL viewer Firefox add-on restores support for the JPEG XL image format after native support was removed, offering users a way to view these images. Users appreciate it as a functional workaround, particularly for static images. However, major drawbacks include lack of animation support, dependency on JavaScript being enabled, and conversion to PNG which compromises some format advantages. Additionally, the removal of its source code repository raises trust issues among users. Despite limitations, it remains a valuable tool until official browser support is reinstated.

Pros

Restores support for the JPEG XL image format in Firefox, which was removed natively.
Provides a functional workaround for viewing JPEG XL images until official support returns.
Works well for static JPEG XL images without animations.
Offers a solution appreciated by users frustrated with Mozilla's removal of native support.

Cons

Does not support animated JPEG XL images.
Requires JavaScript enabled on webpages to display images; doesn't work if JavaScript is disabled.
Converts original JPEG XL images to PNG format internally, leading to loss of some benefits such as better performance or full specification support.
Source code repository and developer GitHub profile have been removed or are private, raising trust concerns.
Does not support features like transparency, wide color gamut, or complex metadata fully.

Not marked as compatible with Firefox Android. And more importantly the source code repository has been deleted or marked private. Very suspicious!

Both the source code repository (i.e. "extension source" link) and the developer's GitHub profile have disappeared.

Extension safety

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

JPEG XL viewer requires a few sensitive permissions. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Browser Add-ons, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.
