About formats

RB is the native ebook format of the Rocket eBook, one of the first commercially available dedicated e-reading devices, developed by NuvoMedia and released in October 1998. Founded by Martin Eberhard and Marc Tarpenning — who later co-founded Tesla Motors — NuvoMedia designed the Rocket eBook as a handheld device with a reflective LCD screen, capable of storing approximately ten books in its internal memory. The RB format packages HTML-based content along with embedded images, metadata, and a table of contents into a single binary container optimized for the device's limited hardware. Content was purchased and downloaded through NuvoMedia's RocketLibrarian desktop software. A notable advantage of the format was its early support for bookmarking, annotation, dictionary lookups, and adjustable font sizing — features now standard on modern e-readers but revolutionary in the late 1990s. The Rocket eBook demonstrated viable commercial demand for dedicated reading devices, paving the way for subsequent platforms from Sony, Amazon, and others. NuvoMedia was acquired by Gemstar-TV Guide International in 2000, which discontinued the device line in 2003. While RB files are largely a historical curiosity today, they can be converted to modern formats using ebook management tools, and the format remains significant as a pioneering chapter in the evolution of digital reading.

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.

Why convert RB to JPS?

RB is an obsolete 1998 ebook format. JPS conversion produces stereoscopic JPEG images viewable on 3D displays or with anaglyph glasses.

What opens JPS files?

StereoPhoto Maker, NVIDIA 3D Vision Photo Viewer, IrfanView with stereo plugin, and various 3D image viewers open JPS files.

Is JPS a real 3D format?

JPS contains side-by-side stereo pairs in JPEG format. When viewed with proper hardware or software, it creates a 3D depth effect.

Does this work without software?

The conversion itself is fully browser-based on Convertio — no software needed. Viewing JPS in 3D requires a stereo-capable viewer.
