If I don't use css OPACITY, I'm back to PDF being about twice the size of the HTML - which is fine.</P> Sat, 26 Apr 2025 16:46:41 GMT GrahamThomason 2025-04-26T16:46:41Z https://connect.mozilla.org/t5/discussions/pdf-bloat-by-repeated-font-embedding/m-p/94230#M36741 <P>When I print an HTML file which has no font changes to Microsoft Print to PDF, the PDF is about 2x the size of the HTNL – which is fine. But I have essentially the same content using a legacy TTF font with very many font changes (for Greek) using &lt;font face="GGTEphesian"&gt; ,,, &lt;/font&gt;. This in the past also gave a factor 2x for the size of the PDF, but now it is 160x, from 6 Megabytes to a Gigabyte. I suspect the font is being embedded again at every &lt;font&gt; keyword. &nbsp;Here is a typical fila in question</P><P><A href="https://www.faraboveall.com/050_BibleTranslation/NTinHTML_AVorder.html" target="_blank">https://www.faraboveall.com/050_BibleTranslation/NTinHTML_AVorder.html</A></P><P>GGTEphesian Font available here</P><P><A href="https://www.faraboveall.com/040_Fonts/01_Fonts.html" target="_blank">https://www.faraboveall.com/040_Fonts/01_Fonts.html</A></P><P>Please undo / fix the change which causes the PDF bloating.</P> Wed, 23 Apr 2025 10:47:39 GMT https://connect.mozilla.org/t5/discussions/pdf-bloat-by-repeated-font-embedding/m-p/94230#M36741 GrahamThomason 2025-04-23T10:47:39Z https://connect.mozilla.org/t5/discussions/pdf-bloat-by-repeated-font-embedding/m-p/94510#M36872 <P>OK.
