About formats

PIX is a raster image format originally developed by Alias Research (later Alias|Wavefront, then acquired by Autodesk) in the mid-1980s for use with their 3D animation and modeling software running on Silicon Graphics workstations. The format stores uncompressed 24-bit RGB image data in a straightforward scanline-by-scanline layout preceded by a minimal header containing the image width and height. PIX was the native output format of Alias's rendering engines, used to store individual frames of 3D animations and rendered stills from software that would eventually evolve into Maya, one of the most influential 3D content creation tools in entertainment history. The format's design reflected the priorities of high-end production rendering: raw speed for writing individual frames during batch renders, exact pixel fidelity with no compression artifacts, and compatibility with the hardware framebuffers used in professional compositing suites of the era. One advantage of PIX is its rendering pipeline heritage — the format can be read by tools throughout the VFX and animation industry, and legacy PIX sequences from Alias-era productions represent irreplaceable primary assets from foundational works in computer animation. The format's simplicity provides another practical benefit: with no compression overhead, metadata complexity, or container parsing required, PIX files can be read and written with minimal code, making them trivial to incorporate into custom rendering and compositing pipelines. PIX files are supported by ImageMagick, GIMP, XnView, and various professional compositing tools.

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.

Frequently Asked Questions

Why convert PIX to ICO?

Most image tools cannot open PIX files directly. ICO output lets you view, edit, and distribute images from early 3D animation and VFX easily.

What programs open ICO files?

You can open ICO files with any standard image viewer. Windows Photo Viewer, macOS Preview, GIMP, and web browsers all support ICO.

What makes PIX files historically important?

PIX images come from Alias PowerAnimator, the software behind groundbreaking CGI in early blockbuster films. They represent a pivotal era in VFX.

What happens to uploaded files?

Your PIX files are processed on secure servers, then deleted automatically. Converted ICO files are available for 24 hours, then erased.

Does converting PIX to ICO lose quality?

Conversion preserves the quality present in the PIX original. Any limitations come from the source resolution, not from the conversion step.
