Add support for AVIF and JPEG XL image formats #987
Description
Feature Request: AVIF and JPEG XL Image Format Support
Summary
Request to add support for modern image formats: AVIF and JPEG XL, which offer superior compression and efficiency compared to traditional formats like PNG, GIF, and JPEG.
Motivation
- AVIF support: Chrome 85+, Firefox 93+, Safari 16+ (increasingly becoming the standard)
- JPEG XL support: Chrome 145+, Firefox 152+, Safari 17+
- AVIF is now being used universally across many websites, often replacing WebP, JPEG, and PNG
- Key advantages:
- More efficient compression compared to PNG/GIF (even in lossless conversion)
- Better quality-to-size ratio compared to JPEG
- Native animation support (like GIF but more efficient)
- Newer format with strong industry adoption
Current Status
AVIF is already widely supported and becoming more universal. JPEG XL support is growing with recent browser versions.
Suggested Implementation
Implement support for these formats while maintaining backward compatibility with existing image formats. Consider:
- Checking Laravel image handling capabilities (Linkstack's current framework)
- Progressive enhancement approach to support older browsers
- Resource compatibility with current Laravel version
Resources
- AVIF Format Specification
- AVIF Browser Support (Can I Use)
- JPEG XL Supported Software
- JPEG XL Official Site
This feature request was submitted based on Discord community discussion and feedback.

As long as these formats behave like any other of our supported file types, this can be implemented by updating the validation.
What we can't really do is convert or compress anything, at least on the backend.
If we update the upload form we could do this client side, using js.
We could add a config option to customize the supported file types. This might make this process more streamlined. Optionally this could then also be used to enable SVG support.
If you want to use these image formats right now the system should support these already. I think in the assets/LinkStack folder look for your image, copy the file name without the extension, delete it and upload your preferred image format and rename the file to the previous file name.
You may have to restart your server for this to apply but it's worth a try if you need this file format for yourself.
