A simple command line tool to attempt at reducing the size of your humongous pptx file.
It doesn't touch your original file and generates a new one, so it should be reasonably safe. Use at your own risk!
- Convert TIFF files to PNG (lossless)
- Remove unused slide layouts and masters
- Remove unused associated medias
go install ./cmd/pptoptimizer
pptoptimizer -h
pptoptimizer -f myhugepresentation.pptx -a
This command creates a hopefully smaller myhugepresentation.new.pptx, applying all possible optimizations.
By default, the only optimization applied is conversion of TIFF pictures to PNG.
