iQIYI optimized its app’s visual experience by progressively replacing JPG with WebP, HEIC, and finally AVIF—using a caplist‑driven CDN, self‑developed decoders and on‑demand production pipelines—to cut image sizes, reduce CDN bandwidth by over 30 % and maintain quality across static, transparent and animated assets.
The guide shows how to shrink a Baidu iOS app by converting PNGs to HEIC within Asset Catalogs—leveraging Xcode’s actool for compression, avoiding pngquant‑induced alpha issues, and employing combined static LinkMap/Mach‑O parsing and runtime isa‑flag checks to prune never‑instantiated classes.
The article details Baidu’s iOS bundle‑size reduction strategy by converting PNG/JPG assets to HEIC using macOS tools or ImageMagick, storing them in Asset Catalogs for iOS 10+ compatibility, handling alpha‑channel quirks, and employing combined static‑link‑map and runtime class‑initialization analysis to safely prune unused Objective‑C classes.
The article details Baidu’s iOS image‑size reduction strategy, combining automated detection and removal of unused PNG/WebP assets, migration to Xcode’s Asset Catalog for lossless compression, and selective conversion to HEIC format, which together shaved roughly 9.75 MB from the app bundle.
The article details Baidu APP iOS package size reduction by identifying and removing unused images, converting resources to Asset Catalogs, and leveraging HEIC and appropriate compression, achieving a 9.75 MB saving while outlining scripts, regex extraction methods, and best‑practice recommendations.
