About formats

CMX (Corel Presentation Exchange) is a vector graphics exchange format developed by Corel Corporation, introduced with CorelDRAW 5 in September 1994. Designed as a cross-application interchange format within the Corel product suite, CMX stores vector objects, text, bitmaps, and rendering attributes in a structure accessible to CorelDRAW, Corel PHOTO-PAINT, Corel Presentations, and other Corel applications without requiring each program to understand the full CDR native format. The format uses a chunk-based architecture that encodes geometric primitives, fill patterns, outline properties, and color definitions in a standardized way, supporting both 16-bit and 32-bit variants. CMX gained significance beyond the Corel ecosystem through its adoption by third-party applications and its role in clipart distribution — many vector art collections from the mid-to-late 1990s shipped in CMX format. One advantage is interoperability within design workflows: CMX provided a practical bridge for moving vector content between different Corel applications while preserving visual fidelity, gradients, and transparency attributes. The format's inclusion of both vector and bitmap data within a single file is another strength, allowing complex mixed-media illustrations to be exchanged as self-contained units. Microsoft also added CMX import support to some Office applications, expanding the format's reach. While modern Corel applications primarily use CDR for native work and export to SVG, PDF, or EPS for interchange, CMX files from the CorelDRAW era remain widely encountered in legacy asset libraries.

AVIF (AV1 Image File Format) is a modern image format derived from the AV1 video codec, developed by the Alliance for Open Media and specified in February 2019. The format leverages the intra-frame coding tools of AV1 — a royalty-free video codec backed by Google, Apple, Microsoft, Amazon, Netflix, and other major technology companies — to compress still images with substantially higher efficiency than JPEG, PNG, or even WebP. AVIF stores images in the HEIF (High Efficiency Image File Format) container, supporting both lossy and lossless compression, HDR (high dynamic range) with wide color gamuts up to 12-bit depth, alpha transparency, and animated sequences. At equivalent visual quality, AVIF files are typically 30-50% smaller than WebP and 50-70% smaller than JPEG, representing the largest compression improvement in mainstream image formats in over a decade. One advantage is exceptional compression efficiency — AVIF delivers visually indistinguishable images at dramatically lower file sizes, directly reducing bandwidth consumption and improving page load times for web content. The royalty-free licensing model provides another key strength: unlike HEIC/HEIF which relies on patent-encumbered HEVC, AVIF's AV1 foundation is free for anyone to implement without licensing fees. Browser support has reached broad adoption, with Chrome, Firefox, Safari, and Edge all rendering AVIF natively. The format is rapidly gaining adoption for web images where quality-to-size ratio is paramount.
