About formats

CDR is the native file format of CorelDRAW, a vector graphics editor developed by Corel Corporation and first released for Windows in January 1989. The format stores complex vector illustrations using a RIFF-based container structure (Resource Interchange File Format), organizing page content, object properties, color palettes, and metadata across multiple data chunks. CDR supports a comprehensive range of vector objects including Bezier curves, rectangles, ellipses, artistic text, paragraph text, powerclips, drop shadows, transparency lenses, contours, blends, envelopes, and multi-page document layouts. Each new major release of CorelDRAW introduces an updated CDR version, sometimes adding features that are not backward-compatible with older software versions. One notable advantage is rich feature density — CDR files can contain extremely complex artwork combining vector objects with embedded bitmap effects, multi-point color fills, and mesh fills, all within a single native document. The format's strong presence in certain professional niches is another practical strength: sign-making, screen printing, engraving, and vinyl cutting industries widely standardize on CDR as their primary working format, with direct output to cutting plotters and production equipment. While CorelDRAW originated as a Windows application and CDR remains most fully supported on that platform, import support exists in competing editors including Inkscape, Adobe Illustrator, and LibreOffice Draw.

ICO is the icon file format for Microsoft Windows), introduced with Windows 1.0 in 1985 and serving as the standard container for application icons, file type icons, and shortcut icons throughout the Windows ecosystem. An ICO file bundles multiple image variants within a single container — each at different sizes (16x16, 32x32, 48x48, 256x256, and others) and color depths (4-bit, 8-bit, 24-bit, 32-bit with alpha) — allowing Windows to select the most appropriate image for each display context, from tiny taskbar buttons to large desktop icons. The container structure consists of an ICONDIR header, an array of ICONDIRENTRY records describing each variant, and the image data itself. Since Windows Vista, ICO files support embedded PNG-compressed images for the larger sizes (typically 256x256), dramatically reducing file size while maintaining quality with full alpha transparency. One advantage is automatic size adaptation — Windows pulls the optimal resolution from the ICO container for each context (Explorer list view, desktop tile, Alt-Tab preview), ensuring crisp display without the application managing separate image files. The format's operating system-level integration is another core strength: ICO files serve as the identity mechanism for executables, file associations, and shortcuts across all Windows versions, and web browsers use favicon.ico for website identity in tabs and bookmarks. ICO creation and editing is supported by image editors like GIMP, Inkscape, and dedicated icon tools, and the format remains essential for Windows application development.
