About formats

TXT (Plain Text) is the most fundamental digital document format, storing unformatted text as a sequence of character codes with no embedded styling, layout instructions, or metadata beyond the characters themselves. The foundation of plain text computing traces to the ASCII standard published in 1963 by the American Standards Association (now ANSI), which defined 128 character codes including uppercase and lowercase Latin letters, digits, punctuation, and control characters. Modern plain text files typically use UTF-8 encoding, a variable-width Unicode scheme that encompasses virtually every writing system worldwide while maintaining backward compatibility with ASCII. Line endings vary by platform convention — LF on Unix/macOS, CR+LF on Windows — though most contemporary tools handle both transparently. One advantage is absolute universality — TXT files can be created, read, and edited on every computing device ever manufactured, from 1960s mainframes to modern smartphones, without any specialized software. The minimal overhead is another core strength: plain text carries zero formatting baggage, making TXT files ideal for configuration files, log output, data interchange, source code, scripts, and any context where content must be processed programmatically. Plain text serves as the substrate for structured formats like CSV, JSON, XML, YAML, and Markdown, and remains the input/output medium for virtually all command-line tools and programming environments. Despite decades of richer alternatives, TXT endures as the one truly universal document format.

HEIF (High Efficiency Image File Format) is a container format for images and image sequences standardized by the Moving Picture Experts Group as ISO/IEC 23008-12, first published in 2015. HEIF is built on the ISO Base Media File Format (ISOBMFF, the same container used for MP4 video), providing a flexible structure that can hold single images, image collections, image sequences (like animations or bursts), and derived images with non-destructive editing operations. The container is codec-agnostic — while the most common implementation pairs HEIF with HEVC/H.265 compression (branded as HEIC by Apple), the standard also accommodates AV1 compression (creating the AVIF variant), H.266/VVC, and other future codecs. HEIF supports features that JPEG lacks: 10-bit and 12-bit color depth, wide color gamuts (Display P3, BT.2020), lossless compression, alpha transparency, depth maps, thumbnail images, and Exif/XMP metadata — all within a single file. Auxiliary image items can store computational photography data like depth maps, HDR gain maps, and semantic segmentation masks. One advantage is the format's future-proof architecture: by separating the container from the codec, HEIF can adopt newer, more efficient compression technologies without changing the file structure, metadata handling, or application-level APIs. The substantial compression improvement over JPEG is another core strength — HEVC-based HEIF typically achieves 40-50% file size reduction compared to JPEG at the same visual quality, beneficial for storage and bandwidth. HEIF is supported by Apple's ecosystem (iOS, macOS), Windows 10/11, Android 10+, GIMP, ImageMagick, and Adobe products.
