The performance score ranges from 0 to 100, with 90 or above considered excellent (green). Scores between 50 and 89 indicate areas that need improvement (orange), while scores below 50 are marked as poor (red) and may indicate significant media optimization issues. Striving for a score of 90 or higher ensures your website delivers fast, optimized media for a superior user experience.
ImageKit uses Lighthouse 12.2.0 to emulate both mobile and desktop environments for accurate performance testing. For mobile, it simulates a Moto G Power with a screen resolution of 412x823 and a Device Pixel Ratio (DPR) of 1.75, using HeadlessChromium 128.0.0.0 running on Node.js.
For desktop, it emulates a screen resolution of 1350x940 with a DPR of 1, also using HeadlessChromium 128.0.0.0. This ensures that your media is optimized for both mobile and desktop users, taking into account screen size, resolution, and device capabilities.
ImageKit uses a Lighthouse-based performance analysis tool to evaluate your website's media assets. It assesses image and video optimization across various factors, including appropriate sizing, lazy loading, and the use of modern formats like WebP, AVIF and AV1 for videos, providing recommendations to enhance performance.
The performance score is determined based on the impact of various media optimization audits. Each audit, such as properly sizing images, using modern image and video formats (e.g., WebP, AV1), and deferring offscreen media, is assigned a weight reflecting its importance. ImageKit prioritizes factors that most improve load times and user experience.
ImageKit automates media optimization by converting images to next-gen formats like WebP and resizing them based on device resolution. For videos, ImageKit recommends formats like WebM with VP9 or AV1 for superior compression without quality loss, ensuring faster load times and reduced data consumption.
Modern formats like WebP, AVIF, VP9, and AV1 provide better compression than traditional formats, reducing file sizes and improving load times. These formats maintain high quality while lowering data usage, which is critical for delivering faster, more efficient websites, especially on mobile networks.
Without optimization, large images and videos can slow down your site, leading to longer load times, higher bounce rates, and lower search engine rankings. Using outdated formats and improperly sized media increases data consumption, which can frustrate users, especially on slower connections.
Optimizing media with ImageKit improves your website’s speed, which positively impacts SEO rankings. Faster websites also engage users better, leading to lower bounce rates and higher conversions, particularly on image- and video-heavy pages.
Yes, ImageKit is designed to optimize both images and videos. It automatically converts images to formats like WebP and AVIF based on image content and device capabilities. Similarly, it converts videos to modern formats like WebM with VP9 or AV1 for efficient streaming and playback.
