JPS to JPG Converter

You have a .jps file, probably a 3D photo made for a stereo viewer, and normal image programs do not offer to open it. This converter reads it and saves an ordinary picture on your own device. The two camera views stay together in one image, so you can see exactly what the file contains before deciding what to do next.

How to convert JPS to JPG

  1. Add your JPS files by dropping them, clicking the drop zone or pasting.
  2. The output format is already set to JPG. Adjust quality or size if you need to.
  3. Press Convert and compare the original and new size for each file.
  4. Download each file or all of them as a ZIP.

When to convert, and when not to

  • You want to preview or share a stereo photo in a program that does not know the .jps extension.
  • You need a plain picture to attach to a message or insert into a document.
  • You want to inspect both views side by side before cropping one of them in an editor.
  • Do not use this tool if you need to split the left and right views into two separate files, because it does not separate them.

What changes

  • The picture is written out as it appears, with the left and right views side by side in one image.
  • The tool does not split, swap or align the two views, and it does not create a 3D or anaglyph picture.
  • The result is a new lossy JPG, so the quality slider controls the detail kept against file size.
  • Metadata such as camera details and location is not carried over to the new file.
  • A rotation tag, if present, is applied before saving.

What is inside a JPS file

A JPS file is a JPEG that holds two photographs taken from slightly different positions, one for each eye. They sit next to each other in a single wide picture. Stereo viewers and some 3D software read that layout and show each half to the matching eye, which produces the sense of depth.

An ordinary image viewer has no idea about that. It just sees a very wide picture made of two near-identical halves. That is why the file may look odd in a normal program and why many programs refuse it based on the extension alone.

What you get after converting

The converter gives you exactly that wide picture as a standard file, ready to open anywhere. Nothing about the depth effect is added or removed, because the effect depends on how a viewer shows the two halves, not on the file format.

If you want only one view, crop the left or right half in a picture editor after converting. If you want to view the pair in 3D, use a stereo viewer or a headset that accepts side-by-side pictures. Many of those accept ordinary JPG files laid out this way.

Choosing the output format

JPG keeps the file small and is accepted nearly everywhere. PNG avoids another round of lossy compression, which can matter if you will edit the pair afterwards, but the file is larger. Compare the sizes shown for your own picture before you convert a whole folder.

Privacy: your files stay on your device

  • The tool decodes, resizes and encodes your pictures with your browser. The files are never sent to a server.
  • To check it yourself: open the browser developer tools (F12), open the Network tab, convert a file, and look for any request that carries your image. You will see none.

Frequently asked questions

Does the tool make a 3D image?

No. It saves the two views side by side as one ordinary picture. Showing them in 3D needs a viewer that supports side-by-side stereo.

Can I get the left and right pictures as separate files?

Not with this tool. Convert first, then crop each half in an image editor.

Why does the picture look doubled?

That is normal. The file holds one photo for each eye, placed next to each other.

Will the converted picture be lower quality?

A little, since JPG is lossy and the picture is saved again. A high quality setting keeps the change small.

Is my stereo photo uploaded?

No. Everything happens in this browser tab and the file stays on your device.

Can I convert it to PNG instead?

Yes. Choose PNG on the options panel to avoid a second lossy pass.
