JPS to JPE Converter
FileFlip converts JPS to JPE entirely inside your browser, using ImageMagick compiled to WebAssembly. The file is never uploaded to a server: it is read off your disk, converted on your own machine, and saved back by the browser. That means no file-size limit, no queue and no account.
How do I convert a JPS file to JPE?#
- Drop your JPS file onto the converter at the top of this page, or click it to pick one from your computer. You can add as many as you like.
- Leave the target set to JPE and the conversion starts on its own. FileFlip downloads 14.1 MB of WebAssembly the first time and nothing after that, then runs ImageMagick on your own machine.
- Save the JPE file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting JPS to JPE lose quality?#
Yes, a little. JPS and JPE are both lossy, so the file is decoded from one encoding and written into another, and detail goes each way. A single conversion is usually impossible to spot; converting back and forth repeatedly is not.
Is it safe to convert JPS files online?#
Yes, because nothing is uploaded. FileFlip converts JPS files inside the browser tab you already have open, using WebAssembly builds of the same engines a desktop converter would install. Your file is read from your own disk into the page's memory, and no request carrying it is ever made.
You do not have to take that on trust. Open your browser's network panel, run a conversion, and you will see the engine come down and your file go nowhere. There is no upload, no server-side copy, no retention window, and no account tied to what you converted.
How FileFlip works lists every engine, its version and its download size, and shows how to check for yourself that nothing leaves your machine.
What JPS to JPE actually does to the file#
Converting JPS to JPE runs on ImageMagick, downloads 14.1 MB of WebAssembly the first time and nothing after that, decodes one lossy encoding and writes another, keeps EXIF metadata and ICC colour profile.
| Engine | ImageMagick |
|---|---|
| Conversion path | One step: JPS → JPE |
| Downloaded to your browser | 14.1 MB, once, then cached by your browser |
| Quality | Lossy, second generation |
| You get back | One file |
| Where it runs | In a background worker, so the page stays responsive |
What survives the conversion
| What is in the file | This conversion | Why |
|---|---|---|
| EXIF metadata | Kept | Carried through into the converted file. |
| ICC colour profile | Kept | Carried through into the converted file. |
What is a JPS file?#
A JPS file is an ordinary JPEG photograph that holds two views of the same scene side by side, one for each eye, flagged as a stereo pair by an APP3 marker that most software simply ignores.
Save a stereo pair as JPS when the destination software, such as StereoPhoto Maker or an anaglyph viewer, reads the APP3 stereo marker and the pair needs to travel as one file.
Convert JPS to a plain JPG when only the flat side-by-side image matters, or split it into two separate JPGs when software needs the left and right views on their own.
What is a JPE file?#
A JPE file is a JPEG image saved with a less common three-letter extension, identical in every byte to a file ending in .jpg or .jpeg, dating from systems that limited filenames to three-character extensions.
There's no reason to choose JPE deliberately today; it exists only because early operating systems limited extensions to three characters, which .jpg already satisfies.
Rename or convert JPE to JPG when a website, app, or content system doesn't recognize the .jpe extension, since the underlying image needs no re-encoding to do it.
JPS to JPE questions people ask#
What is a JPS file?
A JPS file is a standard JPEG image containing two side-by-side views of the same scene, one per eye, for stereoscopic 3D viewing. An APP3 marker inside the file identifies it as a stereo pair, but the underlying image data is ordinary JPEG.
Can I open a JPS file like a normal JPEG?
Yes. Because a JPS file is a valid JPEG, any JPEG viewer opens it, but it will show the uncropped double-wide pair as a single flat photo rather than a 3D image, since ordinary viewers don't read the APP3 stereo marker.
How do I view a JPS file in 3D?
Open a JPS file in stereo-aware software like StereoPhoto Maker, which reads the APP3 marker and can display the pair as an anaglyph, a cross-eyed or parallel side-by-side view, or feed it to a 3D display. Most JPS files on the internet use the cross-eyed arrangement, with the right-eye view stored on the left.
What is a JPE file?
A JPE file is a standard JPEG image with a less common three-letter extension; the format itself is identical to .jpg or .jpeg. The variant extension dates back to systems that limited file extensions to three characters.
