Convert JPG to TNS

Converting JPEG Images directly to TI-Nspire Documents (.jpg to .tns conversion), most likely, relates to users attempting to transfer JPEG images to the TI-Nspire series of graphing calculators (developed by Texas Instruments).

That is certainly possible, you will, however, need the correct size of your image file, as only a limited pixel size is transferrable.

Look for dedicated tools provided by Texas Instruments allowing users to transfer images, texts and documents to a calculator device.
