If you are still uploading JPEGs and PNGs to your CMS, you are publishing images in formats that were designed for the web of the 1990s. JPEG was standardized in 1992. PNG followed in 1996. Both were designed at a time when broadband internet did not exist and mobile devices were not a consideration. In 2026, there is a better option that every major CMS platform supports: WebP.
What WebP is and where it came from
WebP is a modern image format developed by Google and released in 2010. It uses more sophisticated compression algorithms than JPEG and PNG, delivering significantly smaller file sizes at equivalent visual quality. A JPEG image at 200KB typically becomes a WebP at around 120-140KB — a reduction of 30-40% with no perceptible difference in quality. WebP also supports transparency (like PNG) and animation (like GIF), making it a single format that covers most web image use cases.
What this means for your CMS
File size translates directly to page load time. Page load time translates directly to user experience and search engine ranking. Google's Core Web Vitals — the metrics that directly affect your site's ranking — include Largest Contentful Paint (LCP), which measures how quickly the largest visible element on a page loads. For most content pages, that element is a hero image. Publishing that hero image as a WebP instead of a JPEG can improve your LCP by 200-400 milliseconds — a meaningful difference in Google's scoring. For a CMS-driven marketing site with dozens of image-heavy pages, switching to WebP across all images compounds that improvement site-wide.
CMS support in 2026
WebP is now natively supported by every major CMS and is the recommended format across the board. WordPress has supported WebP uploads since version 5.8. Webflow accepts WebP natively and recommends it for all web images. Squarespace converts uploaded images to WebP automatically. Shopify serves WebP to supported browsers automatically. If your CMS is on this list — and virtually every modern CMS is — you can start uploading WebP files today with no configuration required.
The picmagIQ advantage
Most tools that export WebP are converters — they take a JPEG, re-encode it as WebP, and deliver a smaller file with the same flat digital look. picmagIQ combines color grading and WebP export into a single workflow. You apply a cinematic film look, export as WebP, and receive a finished file that is both visually graded and web-optimized. One tool, one step, one file ready for your media library.
