Compression ratio 0.19%

[sanderjson]

Hello I am trying to compress a pdf from the unicli. Everything appears to be working however the compression is negligible (0.19%). This pdf does contain some large images - so I am not sure if there is something wrong with my command.

The watermark does show up as expected on each page.

$ ./unipdf optimize /path/to/myLargeFile.pdf -q 75 -P 100

@sanderjson Can you share the PDF file so we can check? Also might be worth updating the unipdf for the repository to latest version.

@sanderjson We have updated unipdf-cli to newest unipdf. Can you try again? And we do need the file in order to debug this.

[sanderjson]

yes I can update and try again, if the issue persists I can link this file later this evening

ok I have downloaded the latest version and I have tried optimizing a few different files with similar results. One pdf I tried to opimize resulted in 0.18% through the unipdf-cli but when I dropped it into a compressor website (https://pdfcompressor.com/) it reduced by 98%.

This document for example link compressed ~ 6% with the unipdf-cli but 31% with the online compressor.

Could this be due to an error in my installation?

@sanderjson We need access to the uncompressed input file in order to investigate that. Sorry about the late reply. Was just going through some old issues and seems like this had not been followed up on.
