Apple’s recently announced Safari 17 brings several key updates that promise to improve user experience and web page load times.
Introduced at the annual Worldwide Developers Conference (WWDC23), two new features in Safari 17 worth paying attention to are JPEG XL support and expanded font-sizing capabilities.
As Safari continues to evolve, these updates highlight the ever-changing landscape of web development and the importance of adaptability.
JPEG XL – a game changer for page speed optimization
One of the highlights of Safari 17 is its support for JPEG XL, a new image format that balances image quality and file size.
JPEG XL allows the recompression of existing JPEG files without any data loss while significantly reducing their size, up to 60%.
Page load speed is a crucial factor that search engines consider when ranking websites. With JPEG XL, publishers can dramatically reduce the file size of images on their sites, which can result in faster page loads.
In addition, support for progressive loading in JPEG XL means that users can start viewing images before the entire file is downloaded, improving the user experience on slower connections.
This benefits websites that target regions with slower internet speeds, improving the user experience and potentially reducing bounce rates.

Safari 17 extends the capabilities of font-size-adjust, a CSS property that ensures that the visual size of different fonts is consistent across all possible combinations of alternative fonts.

Conversely, the two-valued syntax provides more flexibility in adjusting different font metrics, supporting a wider range of languages and layout options.

Reimagining SEO strategies with Safari 17
Given these developments, SEO professionals may need to adjust their strategies to take full advantage of Safari 17’s capabilities.
This could involve:
Image optimization: With support for JPEG XL, SEO professionals may want to consider reformatting their website images to this new format.
Web design: Expanded font-size-adjust capabilities might require rethinking design strategies. Consistent font sizes across languages and devices can improve CLS, one of the lifeblood of the Google web.
Performance monitoring: SEO professionals will need to closely monitor the impact of these changes on website performance metrics once the new version of Safari is introduced.
To sum up
Apple’s Safari 17 brings new features that provide opportunities to improve several website performance factors crucial to SEO.
