This application is a local only web instance that can be spun up in termux.

Here is the source code.

Its configured to be a local only service utility although it wouldn’t take much to point this to the web.

After picking a image, you can configure the compression. I found large image files basically require the compression. There is a limit to how much text you can copy…its very large…but the higher quality the image the longer this string of text will be, so you may need to lower the quality if you run into problems.

You can either copy the text directly, or download a blob as the .txt file for transport.
