Textmaker jpg image Compression?

[bolinrs]

Evaluating Textmaker on Win7, saved 1-page blank document to tmdx, file size was 12,477 bytes. Then added 104,371 byte jpg file, saved again. New tmdx file size is only 96,293 bytes. Is Textmaker compressing the jpg? Other explanation?

No, it doesn't do this silently. But .tmdx and .docx are basically ZIP files, so there is some additional (lossless) compression at the document level.

Thanks, that explains it quite well.
