Created attachment 203628 [details] Simple example file from the Candy template If the attached file, made from the Candy template, is minimized, then the file size is not reduced much. This happens because of the 4 large PNG inside, only one gets converted to jpg and reduced in size. 1. Open attached file in Impress 2. Tools - Presentation Minimizer 3. Press Finish without changing any setting -> the file size is changed from 1.6 Mb to 1.2, which is not a lot Version: 26.2.0.0.alpha0+ (X86_64) / LibreOffice Community Build ID: c7b3ea692f293346fbbdf2a391d9d971c34fa1f2 CPU threads: 8; OS: Linux 6.8; UI render: default; VCL: gtk3 Locale: hu-HU (hu_HU.UTF-8); UI: en-US Calc: threaded Works like this since this range in 6.0: https://cgit.freedesktop.org/libreoffice/core/log/?qt=range&q=b29bae1064c9f980cc50a667e8b96c5e370326d7..77da7b934d782153be9271605691ceee6c66233a but, nothing is suspicious about these cleanup commits. Anyways, just before this commit it was not good either: nothing was compressed, which is another regression compared to 5.3, where all images were properly compressed. Unfortunately, under linux bibisect repos the oldest of 5.4 is already bad, the latest of 5.3 is still good -> bibisectrequest.

Maybe because almost all are shapes, not images?
Gave it another try, looks like yesterday I was not paying attention to choose the smallest option in the first page of the wizard, which made the difference between 5.3 and 5.4. On the other hand, if I choose the "Email (96 DPI)" option from the dropdown on the first page of the wizard, I'm getting weirdly different results since 7.5: https://cgit.freedesktop.org/libreoffice/core/commit/?id=7243f7c706ceb49d6b3e4dfb8ff72ab43c65dd86 author Noel Grandin <noel.grandin@collabora.co.uk> 2022-12-07 14:08:45 +0200 committer Noel Grandin <noel.grandin@collabora.co.uk> 2022-12-07 17:17:33 +0000 commit 7243f7c706ceb49d6b3e4dfb8ff72ab43c65dd86 (patch) loplugin:unusedmethods Which has indeed touched the minimizer dialog implementation. Before this, the result from minimizing the attached file was 0.2 Mb with all 4 images changed. After this the result is 1Mb, with only one image changed. This behavior gives similar result to choosing "Web (150 DPI)" option, so this has confused me. New steps: 1. Open attached file in Impress 2. Tools - Presentation Minimizer 3. Choose the "Email (96 DPI)" option from the dropdown on the first page of the wizard 3. Press Finish without changing any other setting -> the file size is changed from 1.6 Mb to 1.2, which is not a lot
