One Image, Every Screen: How Vyso Automates Responsive Resizing

Updated on July 7, 2025
Vyso DAM Features & Innovations

Vyso automatically resizes and serves the perfect image variant for every screen, pixel density, and connection—so your users get speed and clarity without bloat.

Serving the right image to the right device shouldn’t require a separate file for every screen size, pixel ratio, or breakpoint.

Yet that’s how many teams still operate—manually generating variants, resizing assets in bulk, or relying on oversized images just to cover all bases.

It’s slow. It’s inefficient. And it doesn’t scale.

That’s why Vyso was built to take responsive image delivery completely off your plate—with a smart system that automatically resizes, formats, and serves the perfect variant based on device, screen density, and network conditions.

You upload one image—we handle the rest.

Upload Once, Deliver Everywhere

With Vyso, there’s no need to upload five sizes of the same asset. You simply upload the original, highest-quality version.

From there, every variant—thumbnail, mobile, retina, 4K, you name it—is generated automatically.

These variants aren’t pre-baked in advance. They’re created on demand, using clean URL parameters that let you specify dimensions, aspect ratio, format, and more—either through your frontend logic or via direct links.

Want a 400px-wide WebP version for mobile? Just request it. Need a square-cropped AVIF thumbnail for a gallery view? One URL change, and it’s done.

Optimization Built Into the URL

Each asset in Vyso can be resized, cropped, and reformatted on the fly using intuitive query parameters. For example:

https://cdn.vyso.io/hero.jpg?w=768&format=webp&fit=cover

The first time this version is requested, Vyso processes it instantly, caches it at the edge, and serves it just like any other asset. Every subsequent request—across any user, page, or device—gets that variant instantly, from the nearest CDN node.

No backend logic. No delay. No duplication of storage or processing.

This approach means your app, site, or CMS can generate responsive images dynamically without writing a custom resizing service or bloating your storage with redundant copies.

Pixel-Perfect Across Devices

Modern screens aren’t just big or small—they’re dense. Retina, 4K, and high-DPI displays demand more than a one-size-fits-all approach. Serving a standard image to a high-density screen means blurry visuals and a bad user experience. Serving a huge image to a low-density screen wastes bandwidth.

Vyso detects device characteristics and delivers appropriately scaled assets based on what the browser supports. That includes pixel density, viewport size, and supported image formats (AVIF, WebP, JPEG).

Your images always look crisp and load fast—no matter where they're viewed.

Cached for Speed, Not Reprocessed Every Time

Every variant generated via URL is cached automatically across Vyso’s global CDN.

That means if ten thousand users across the globe request the same 768px-wide image for mobile—only the first one triggers processing. Everyone else gets the optimized version directly from the edge.

This massively reduces server load, avoids duplicate processing, and ensures lightning-fast delivery even for complex layouts with lots of images.

Built for Real-World Workflows

You don’t need to predefine your breakpoints or pre-generate dozens of asset sizes. Just build your site or app the way you want—with responsive components, dynamic layouts, or lazy-loaded images—and request exactly what’s needed on the fly.

Vyso plays nicely with modern frontend frameworks, headless CMS setups, and static site generators. Whether you're building in Next.js, React, WordPress, or something custom, integration is as simple as inserting a URL.

Responsive image delivery shouldn't be a manual process—or a performance headache.

With Vyso, a single high-quality upload becomes a smart, flexible source for every screen your users touch. Automatic resizing. URL-driven optimization. Global caching. All handled behind the scenes.
