About formats

AZW3, also known as Kindle Format 8 (KF8), is Amazon's advanced ebook format introduced in November 2011 alongside the first Kindle Fire tablet. It replaced the older MOBI-based AZW format with a substantially more capable layout engine built on HTML5 and CSS3 subsets, enabling fixed layouts, embedded fonts, SVG graphics, drop caps, and other typographic refinements that were impossible in earlier Kindle formats. Internally, an AZW3 file packages content in a structure derived from EPUB, wrapped in Amazon's proprietary Palm database container with optional DRM protection. The format supports both reflowable text for novels and fixed-layout pages for comics, cookbooks, and children's titles. One major advantage is rich formatting fidelity — publishers can produce visually sophisticated ebooks with complex page designs, nested tables, and precise font control that render consistently across the Kindle ecosystem. Another strength is backward compatibility: AZW3 files can bundle a MOBI fallback section so older Kindle hardware still displays the content, even without full KF8 rendering. The format integrates tightly with Amazon's Kindle platform, supporting features like X-Ray, Whispersync page tracking, and in-book dictionary lookups across millions of devices and apps 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 AZW3 to JPS?

JPS creates side-by-side stereoscopic pairs — a creative way to turn flat AZW3 ebook pages into 3D-viewable image content.

What applications open JPS files?

StereoPhoto Maker, IrfanView (stereo plugin), JPS Viewer, 3D-capable displays, and VR headset software support JPS files.

Can JPS produce real 3D from flat pages?

JPS stores a side-by-side pair — for flat content it produces a planar stereo view, which still works with 3D viewers.

Is JPS the same as JPEG?

JPS uses JPEG compression but packages left and right eye views together in one file — a specialized JPEG variant for stereo.

Does this cost anything?

No — AZW3 to JPS conversion is free on Convertio. Premium plans add more processing power for heavy or batch use.
