PSD to HTML Conversion

Design files are promises; code is delivery. In a world where Core Web Vitals directly impact search rankings and user retention, the transition from design to code must be executed with absolute precision. Whether your source is Photoshop, Figma, Sketch, or Adobe XD, we hand-code each pixel into semantic, performant, and accessible frontend code. At SoniNow, we treat every conversion as a frontend architecture project—building foundations that load fast, rank well, and look exactly like the design that inspired them.

Pixel-Perfect Implementation

Our frontend engineers match the original design with forensic precision, ensuring that every pixel from your design file is faithfully reproduced in the browser.

Layer-by-Layer Verification

We use a layer-by-layer overlay comparison technique, placing the original design file over the rendered HTML to verify alignment, spacing, typography, and color accuracy at every breakpoint. Adjustments are made at the code level until the rendered output exactly matches the approved design.

Design File Preparation

Before we write a single line of code, we prepare and audit your design files. We organize layers, identify typography specifications, extract color values, define spacing measurements, and document interaction states. This preparation ensures that nothing is lost in translation from design tool to browser.

Responsive and Fluid Layouts

Modern websites must adapt seamlessly to every screen size. We implement responsive architectures that preserve design integrity across devices.

Fluid Grid Systems

We build on CSS Grid and Flexbox, implementing fluid grid systems that scale gracefully from a 320-pixel phone screen to a 2560-pixel desktop monitor. Column widths, gutters, font sizes, and spacing are defined in relative units, ensuring that your layout adapts naturally without requiring rigid breakpoint-specific overrides.

Responsive Image Strategy

We implement srcset, sizes, and picture elements to serve the optimal image resolution for each device and viewport. Combined with automatic format negotiation (WebP, AVIF, JPEG) and lazy loading, your images are always sharp but never slow.

Cross-Browser Compatibility

Your website must work flawlessly for every visitor, regardless of their browser choice. We test and optimize across the complete browser landscape.

Testing Matrix

Every project is tested on Chrome, Firefox, Safari, Edge, and Samsung Internet across Windows, macOS, iOS, and Android. Feature detection, polyfills, and progressive enhancement ensure that functionality degrades gracefully when browsers lack cutting-edge CSS or JavaScript support.

Legacy Browser Strategy

For projects that require support for older browsers, we implement a progressive enhancement approach. Core content and functionality are accessible without modern CSS or JavaScript, while enhanced experiences are layered on for users with capable browsers.

Performance Optimization

Clean, optimized code is the foundation of fast-loading websites. We build performance into every line.

Minimal Code Footprint

We write clean, minimal HTML, CSS, and JavaScript with no framework overhead unless the project requires it. CSS is organized using a utility-first or BEM methodology that prevents class bloat and specificity conflicts. JavaScript is modular, scoped, and deferred to avoid blocking page rendering.

Build Tool Integration

For larger projects, we configure build pipelines using Vite, Webpack, or Parcel that automate code minification, CSS purging, image optimization, cache busting, and bundle splitting. The output is production-ready code that loads fast and is easy to deploy.

Framework Integration

Beyond static HTML, we convert designs into component-based frameworks for dynamic applications.

React and Next.js Components

We transform your design files into reusable React or Next.js components with TypeScript type definitions, Storybook documentation, and responsive props. Each component is isolated, testable, and ready for integration into a larger application architecture.

Asset Packaging and Documentation

Deliverables include the complete component tree, export configurations, integration documentation, and a style reference. Your development team receives a drop-in-ready frontend package that matches the design specification exactly.
