bnanes / shrink-pdf Goto Github PK

Hi,

There is Peter Szabo's pdfsizeopt which works by applying various image lossless image compression techniques to the embedded images in the original PDF.

Is shrink-pdf lossless? Can you provide some benchmarks/comparisons etc. against pdfsizeopt?

Please sign your binaries so they will run in Mavericks

Thanks for this nice piece of sw.
I wish to comment that output seems much cleaner than ghostcript based solutions.
I believe that PDFBox based tools (I also tried PDFFlattener but I need a pure CMD based approach - with same good outcomes) provide better optimization, in the sense that for same size output resolution is better.

Just one comment. For my 1GByte pdf input I had to add -Xmx2048m otherwise the run fails.

By the way, could I ask you to have a view to https://github.com/cityssm/pdfFlattener

In my tests, for my PDFs, I get 25% smaller files with your SW than with the pdfFlattener for at my eye similar quality, but would like to know if your sw also removes any active content.

If not, could you have a view to cityssm/pdfFlattener#4
Perhaps you could contribute easily a pull request to introduce a no gui version in pdfFlattener, or perhaps to fork or create one... I would do myself, but I am really illeterate on these subjects, just a CMD user... I tried to understand PDFBox and I am really not knowing where to start...

Thanks in advance!

This program has worked for me before but for some reason it is giving me rather strange output on these specific pdfs.
earth114_lect02.pdf
earth114_lect02_SHRUNK.pdf

I'm using the tool to compress lecture slides from all my past classes, so I don't have the source files. It has seemed to work fine for all my other classes.

There are two issues with the shrink-pdf.sh file in the pre-built app archive. It needs to have its executable bit set (not sure if this is possible in a zip file), and it needs to have unix line endings (i.e. LF instead of CR). Currently the user needs to make these two changes manually, which can be confusing for non-geeks.
