Created attachment 170417 [details] Libreoffice PDF export that demonstrates the increase in size and slow performance Dear all, I try to promote within my workplace the use of free software including LibreOffice. I noticed that if I embed an SVG logos of 400 KiB in an otherwise empty ODT and export this to a PDF, than the PDF has 13MB and many PDF readers (if not all) suffer from huge performance issues in rendering the PDF. I have tried the following PDF readers: 1. Okular (KDE Linux) 2. Acrobat Reader (Windows) 3. Firefox (Linux, I can literally see the individually steps of the logo painting) I would instead expect that the PDF is under 1MB and loads as fast as a PDF file stemming from the Inkscape SVG to PDF export. I assume that the SVG logo uses some features (like gradients) that the LibreOffice export does not handle efficiently.

Confirm a big PDF size in Version: 7.2.0.0.alpha0+ (x64) / LibreOffice Community Build ID: 9d8accf03984a64a4105826e55b221962628eb93 CPU threads: 4; OS: Windows 6.1 Service Pack 1 Build 7601; UI render: default; VCL: win Locale: ru-RU (ru_RU); UI: en-US Calc: CL But when I opened that result PDF in Firefox I saw some drawing of symbols in logo and then scrolling was too fast Export ODT to PDF from LO 5.2 gave me 6 mb PDF file
I have exported the same odt file to pdf using: LibreOffice 6.0.4.2 (x64) CPU threads: 8; OS: Windows 10.0; UI render: default; locale: en-GB (en_GB); Calc: group Also here, the pdf is about 6mb (6.774KB). I have opened the pdf in Acrobat reader and the initial rendering of the logo takes several seconds.
