    APNGKit

    APNGKit

    High performance and delightful way to play with APNG format in iOS

    The APNGKit project is a high-performance framework for loading, displaying, and animating images in the UIKit / AppKit ecosystem (iOS, macOS, tvOS), specifically targeting the APNG (Animated PNG) image format. Unlike traditional static PNG images, APNG supports frame-by-frame animation with full-color images and transparency — yielding better visual fidelity than GIFs while remaining efficient. APNGKit offers a friendly API (e.g. APNGImage, APNGImageView) that behaves similarly to the standard image/image-view pattern, making it easy for iOS/macOS developers to adopt without learning complex new APIs. ...

    sharp

    sharp

    High performance Node.js image processing module

    The typical use case for this high speed Node.js module is to convert large images in common formats to smaller, web-friendly JPEG, PNG, AVIF and WebP images of varying dimensions. Resizing an image is typically 4x-5x faster than using the quickest ImageMagick and GraphicsMagick settings due to its use of libvips. Colour spaces, embedded ICC profiles and alpha transparency channels are all handled correctly. Lanczos resampling ensures quality is not sacrificed for speed. ...

    libavif

    libavif

    Library for encoding and decoding .avif files

    libavif is a portable, open-source C library that implements encoding and decoding for the AVIF (AV1 Image File Format), offering a robust, production-ready way to work with AVIF images across platforms. It supports all AV1-supported YUV formats and bit-depths, including alpha (transparency), and includes command-line tools (avifenc and avifdec) to easily convert to/from AVIF from common image formats like JPEG, PNG, or Y4M. The API is straightforward, allowing applications to integrate AVIF support natively — creating, decoding, compressing, or decompressing images programmatically. Recent developments have added experimental support for HDR gain maps, improved color-space handling (including wide color gamut and high bit depth), and better quality tuning modes for encoding, making libavif a cutting-edge tool for high-quality image compression.
