The Universal Batch Image Compressor & WebP Optimizer Studio by RiazHub is a modern, privacy-focused, browser-based performance suite engineered for web developers, content creators, and digital store owners. Operating 100% locally on your device via HTML5 Canvas 2D and asynchronous Web APIs, this utility allows you to optimize, resize, and transcode up to 50+ images simultaneously into modern WebP, JPEG, or PNG formats without ever transmitting sensitive photos to external servers.
With intelligent aspect-ratio locked downscaling (Full HD 1920px, Web Banner 1200px, Mobile 800px), live compression quality tuning (1%–100%), interactive split-screen before/after inspection, EXIF metadata stripping, and zero-dependency in-memory ZIP archive generation, you can slash image payloads by up to 70%–85% to dramatically improve Google Core Web Vitals (LCP) and boost your website’s PageSpeed score in seconds.
Universal Batch Image Compressor & WebP Studio
Compress, resize, and convert multiple images simultaneously to WebP, JPEG, or PNG with zero quality loss. 100% private in-memory processing with instant ZIP download.

📘 Core Web Vitals & Web Image Optimization Guide
Why WebP Delivers 25%–35% Smaller File Sizes at Equivalent Quality
WebP uses advanced predictive coding and discrete cosine transform algorithms originally developed for video codecs. It predicts neighboring pixel blocks and only encodes residual difference values, drastically reducing redundant image payload compared to legacy JPEG algorithms while offering full 24-bit RGB and 8-bit alpha channel transparency.
Impact on Google Core Web Vitals (Largest Contentful Paint - LCP)
Hero images and product photos are the primary cause of poor LCP scores on modern websites. Downscaling images to actual display breakpoints (e.g., max 1920px for desktop and 800px for mobile) combined with WebP compression ensures assets load within Google's recommended 2.5-second threshold, directly improving search rankings and visitor conversion rates.
Why Stripping Unneeded EXIF Metadata Saves Precious Kilobytes
Raw camera and smartphone photos embed extensive EXIF data including camera serial numbers, exposure configurations, software tags, embedded preview thumbnails, and sensitive GPS geolocation coordinates. Stripping this metadata through our HTML5 Canvas pipeline routinely trims 10 KB to over 60 KB per file before pixel compression even starts.
100% In-Browser Privacy Guarantee
All image processing, scaling, transcoding, and ZIP compilation routines occur 100% locally inside your client web browser memory utilizing JavaScript and HTML5 Canvas API. Zero images, personal files, or confidential documents are ever transferred to RiazHub.com or any third-party external cloud server.
