About formats

DFONT (Data Fork TrueType) is a font file format introduced by Apple with Mac OS X 10.0 in March 2001, created to solve a fundamental compatibility problem in the transition from classic Mac OS to the Unix-based OS X architecture. Classic Mac fonts stored glyph data in the resource fork — a secondary file stream specific to the HFS file system — but OS X's Unix foundation and its use of UFS had no native resource fork support. DFONT relocates the entire resource fork structure into the data fork, wrapping the same TrueType font tables in a resource map that standard OS X typography APIs can read. The file is essentially a resource-fork-less TrueType suitcase. Apple bundled DFONT as the default format for system fonts shipped with OS X, and it remains present in macOS system directories. One advantage is seamless backward compatibility with Apple's existing font rendering stack — the internal structure mirrors classic resource-fork fonts, so CoreText and its predecessors handle DFONTs without any special conversion path. The single-fork design is another practical strength, ensuring that DFONT files survive intact when stored on non-HFS volumes, transferred over networks, or managed by version control systems. While Apple has increasingly moved toward OpenType (.otf/.ttc) for newer system fonts, DFONT files continue to appear in macOS installations and in font collections originating from the OS X era.

JPS (JPEG Stereo) is a stereoscopic 3D image format that stores a left-eye and right-eye view pair within a single JPEG-compressed file, developed by VRex, Inc. around 1997 for use with stereoscopic displays and viewers. A JPS file is technically a standard JPEG file containing a side-by-side stereo pair — the left and right perspective images are placed horizontally adjacent within a single frame, with the full image width being twice the individual view width. The file uses standard JPEG compression and can be opened by any JPEG-compatible viewer (which will show the side-by-side pair as a single wide image), but stereo-aware applications parse the image into its left and right components for proper 3D presentation. JPS files can be viewed with dedicated stereoscopic software, anaglyph viewers (generating red-cyan images for colored glasses), autostereoscopic displays, VR headsets, and hardware like NVIDIA 3D Vision or passive 3D monitors. The format gained renewed interest with the consumer 3D photography boom of the late 2000s and early 2010s, when cameras like the Fujifilm FinePix Real 3D W1/W3 captured stereo pairs natively. One advantage is backward compatibility: because JPS uses standard JPEG encoding, the files work with existing JPEG infrastructure — they can be transmitted, stored, thumbnailed, and even viewed (as flat side-by-side images) without any special software. The format's simplicity is another practical strength — no specialized container or codec is required, and any tool that can crop and display JPEG images can extract individual views. JPS files are supported by StereoPhoto Maker, ImageMagick, and various 3D photo viewers.

Frequently Asked Questions

Why convert DFONT to JPS?

JPS creates side-by-side stereoscopic images — converting DFONT to JPS produces 3D font specimens viewable with 3D glasses, VR headsets, or stereo viewers.

How do I open a JPS file?

StereoPhoto Maker, SPM on Android, and most VR image viewers display JPS. Standard image viewers show the side-by-side stereo pair as a regular image.

Is JPS just a JPEG file?

Essentially yes — JPS uses JPEG compression but contains a side-by-side stereo pair. Any JPEG viewer opens it, but you need stereo software for the 3D effect.

Can I view JPS without special glasses?

Cross-eyed or parallel viewing techniques work without glasses. For the best experience, use anaglyph glasses, a VR headset, or a stereoscopic display.

Is the service free to use?

Convertio provides free DFONT to JPS conversion — fully online, no account needed, no software installation required.
