Here are a few tips on optimizations when using pdf2htmlEX or deploying HTML files produced by pdf2htmlEX.

To Embed or Not to Embed

Resource files can be embedded into the HTML file via Data URI Scheme, or they can be stored separated. The behaviour can be tweaked via the --embed option. Embedding files into HTML will save HTTP requests, at the cost of 1/3 extra space due to the base64 encoding. Publishers should tweak the options carefully based on the actually file sizes and target network environments.

Enable HTTP Compression

HTML file produced by pdf2htmlEX are often slightly larger than the original PDF file. One reason is that PDF has built-in compression support while HTML does not. This can be compensated by enabling HTTP compression on your HTTP server, often gzipped-HTML is smaller than the original PDF.
