Many websites look visually appealing but hide a serious technical flaw behind the scenes: the use of outdated image formats. I see many developers still delivering projects loaded with heavy JPGs and PNGs, treating performance as an afterthought.
At vmoode, our development process does not compromise on technical efficiency. A truly fast website requires images to be handled intelligently, adapting perfectly to the screen of the device the visitor is holding.
The end of legacy formats (JPG and PNG)
Formats like JPG and PNG were created in an era when the internet was static and screens had low pixel density. Today, using them in a professional project is like trying to run a modern engine with low-quality fuel.
We exclusively use WebP (and in specific cases, AVIF). These formats offer superior compression without losing visual clarity. In practice, this means we can reduce an image's weight by up to 80% compared to traditional formats, ensuring your content appears instantly on the user’s screen.
Sizing precision: Neither more nor less
Another common mistake I see in the market is loading images in generic sizes. Many sites force a customer’s phone to download a 4000-pixel image to be displayed in a space of only 400 pixels. This is a waste of bandwidth and processing power.
Our process is intentional:
- Responsive scaling: We create multiple variants of each image where your customer’s browser only downloads the version that fits their screen width perfectly.
- Pixel density: We automatically adjust resolution for Retina displays and standard monitors, maintaining sharpness without overloading the network.
Direct impact on LCP (Core Web Vitals)
Google uses a metric called LCP (largest contentful paint) to measure how long it takes for the largest element on your page to load. Most of the time, this element is a hero image.
When we eliminate unnecessary weight and use modern formats, we ensure this metric stays in the excellence zone with 90+ scores. This not only improves the user experience but also reduces the Customer Acquisition Cost (CAC) in paid traffic campaigns, as the algorithm rewards pages that deliver content fluidly.
We treat every visual asset as a piece of engineering that must be delivered with maximum precision, as optimizing images is not just about making the site lighter, but about removing friction between your brand and your customer. If your current site still relies on technologies of the past, you are paying the price in performance and losing your audience's attention to those who already treat the web with the technical rigor it demands today.
