The Business Need

Modern image conversion tools face a fundamental privacy vs. functionality dilemma. Server-based solutions require uploading sensitive images, while client-side tools often lack professional features. Users need unlimited bulk conversion without compromising privacy or paying subscription fees.

Technical Approach

Leveraged modern browser APIs to create a fully client-side image processing pipeline. Used HTML5 Canvas API for format conversion, File APIs for local access, and CSS clip-path for Interface.

Technology Stack

Primary Technologies

HTML5 CSS3 JavaScript ES6+

Supporting Tools

Canvas API File API Blob API

Integrations

WebP Format JPEG Format PNG Format

Key Features

Interface

Real-time before/after comparison with draggable slider overlay. Users can see exact quality differences pixel-by-pixel as they adjust settings.

Batch Processing with Thumbnails

Process multiple images simultaneously with visual thumbnail navigation. Click any thumbnail to preview in the main comparison view.

Advanced Quality Controls

Granular quality settings with real-time size estimation. Includes compression effort levels for optimal file size vs. processing time balance.
