About formats

FIG is the native file format of Xfig, a free vector graphics editor for the X Window System, originally written by Supoj Sutanthavibul at the University of Texas at Austin in 1985. The format uses a plain-text structure where each graphic object is described on one or more lines with numeric parameters specifying object type, coordinates, line properties, fill attributes, and depth ordering. FIG supports compound objects (groups), polylines, polygons, splines, arcs, ellipses, text strings, and imported bitmaps, each with configurable colors, line styles, arrow heads, and area fills. Files begin with a header line declaring the format version (currently 3.2), followed by a resolution specification and the object definitions. One advantage is exceptional simplicity — the entirely text-based format is trivially parsed, generated, and manipulated by scripts, making FIG popular as an intermediate format in automated diagram generation pipelines. The rich ecosystem of conversion tools is another strength: fig2dev exports FIG files to dozens of output formats including EPS, PDF, SVG, LaTeX picture environments, PSTricks, and TikZ. This made Xfig and FIG especially popular in academic and scientific communities, where authors generate publication-quality figures that integrate seamlessly with LaTeX documents. While graphical tools have evolved since the 1980s, FIG remains in use among researchers who value its scriptability, LaTeX integration, and well-documented format stability.

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.

Frequently Asked Questions

Why convert FIG to HEIF?

Xfig diagrams in FIG format are invisible to most software. Converting to HEIF turns them into universally displayable images.

Where can I open HEIF files?

You can open HEIF files with Apple devices natively, Windows with HEIF codec, GIMP, and Adobe Lightroom.

Does converting FIG to HEIF preserve quality?

Convertio optimizes the conversion to retain as much quality as possible. The output closely matches your original FIG diagram.

Is there an API for FIG to HEIF conversion?

Convertio offers a developer API for automated conversions. Check the API documentation for integration details.

Can I use this converter on any operating system?

The tool is browser-based and works on Windows, macOS, Linux, ChromeOS, and mobile platforms — no OS-specific software needed.

Can I batch convert multiple FIG files to HEIF?

Absolutely. Add several FIG files at once and convert them all to HEIF in a single batch — saves time on bulk tasks.
