Stereoscopic Output

JPS creates a 3D stereo pair from your SFD font rendering — a novel way to present typeface designs in stereoscopic and VR environments.

Cloud Rendering

All processing happens on Convertio servers. No local FontForge or stereo imaging tools required on your machine.

Multi-Device Viewing

View JPS font specimens on 3D TVs, VR headsets, and stereo image viewers — or as a regular JPEG on any standard device.

About formats

SFD (SplineFont Database) is the native source file format of FontForge, the free and open-source font editor originally created by George Williams in 2000 under the name PfaEdit. The format stores a complete font project — glyph outlines (cubic and quadratic splines), advance widths, side bearings, hinting instructions, kerning and OpenType feature tables, naming records, and metadata — in a single human-readable text file. Each glyph is described by its Unicode code point, outline coordinates, reference composites, and anchors, making the entire font design inspectable and diffable with standard text tools. SFD functions as the editable working format during font development, from which finished fonts are compiled to binary formats like OTF, TTF, or WOFF. A primary advantage is version control friendliness — because SFD is plain text, font designers can track changes to individual glyphs, merge contributions from collaborators, and maintain full revision history using Git or any other VCS. The format's completeness is another strength: it preserves every piece of data that FontForge can represent, including TrueType instructions, contextual substitution lookups, and multiple master axes, avoiding round-trip data loss during editing. The SFD specification is publicly documented and has evolved through several versions. FontForge's widespread adoption in the open-source type design community means SFD serves as the source format for hundreds of freely licensed font families distributed worldwide.

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 SFD to JPS?

JPS is a stereoscopic JPEG format for 3D viewing. Convert SFD to JPS to create 3D font renderings viewable in stereo viewers and VR headsets.

How do I view a JPS file?

JPS files open in stereo image viewers like StereoPhoto Maker, 3D TVs, and VR headsets. Standard JPEG viewers show the side-by-side pair.

Does JPS create actual 3D depth?

JPS stores a side-by-side stereo pair. The 3D effect depends on the source content — font renderings appear as a stereo presentation of the glyphs.

Is JPS compatible with regular JPEG viewers?

Yes, JPS is a standard JPEG with stereo data. Any JPEG viewer can open it, though you see both left and right images side by side.

Is the conversion free?

Convertio converts SFD to JPS for free online — no stereo tools or FontForge needed on your device.
