What is a .ICB file?
ICB is a Truevision raster image - the same TGA format used by Targa video boards, here named for the Image Capture Board.
- Did you know
- TGA, ICB, VDA and VST are all the same Truevision raster format under different extensions named after the company’s 1980s graphics cards.
- Truevision's Targa boards in the 1980s were among the first to put true-colour 24-bit images on a PC, and the TGA family of formats grew up around them.
- TGA and its .icb sibling were a staple of early 3D rendering and games, thanks to optional fast run-length compression and an alpha channel.
- What Analyser reads
- Decode and preview extra still-image formats in pure JavaScript - Truevision TGA, QOI, Netpbm (PPM/PGM/PBM), PCX, farbfeld, WBMP, XBM/XPM, Sun Raster and SGI are fully rendered - and read header metadata from codec-heavy formats: Radiance HDR, DirectDraw Surface (DDS) game textures, OpenEXR, JPEG 2000, JPEG XR, EPS/PostScript, Windows WMF/EMF metafiles, Apple ICNS icons, CUR/ANI cursors, MNG and Lottie animations.
- Depth of analysis
- .ICB is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .ICB file
- Drag a .ICB file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
