How Client-Side File Compression Works
Digital media files (images, PDFs, audio, video) frequently contain redundant metadata, unoptimized quantization tables, and inefficient color channel encoding that bloat file sizes. Wivon Tools uses browser-native WebAssembly algorithms to strip bloat and re-encode data structures without requiring any file uploads to cloud servers.
