This web app converts images to a format that can be viewed on a Texas Instruments TI-84+ CE or TI-83 Premium (as well as variants of each) using TheLastMillennial's HD Picture Viewer. Currently only the image format used in version 2.0.0-beta1 is supported, but new features and format changes are expected to be handled by newer versions of this converter as needed.

This converter was written by Peter Marheine and is open source, implemented in Rust with a custom HTML and Javascript frontend. The source code can be found at gitlab.com/taricorp/hdpictureconverter-rs and can be freely copied or modified subject to the terms of the (permissive) license found there.

Bug reports and feature requests for this converter should be made via the Gitlab issue tracker. Issues with the viewer itself should be reported to TheLastMillennial instead, such as on GitHub.
