Thread: how to make the PDF file smaller

Hi,

I'm kind of new to Latex, but was still able to write a paper using TexWork software.

My problem is that the PDF file I create it too big. For 73 pages with some figures (just 10 kb png files) it's about 800 kb.

I need it to be much smaller, even if it reduce the resolution of it. I saw some codes to convert it, but not sure how to use them, the way I created the PDF was with the TexWork feature.

It's very urgent.

Thank you very much,

Ideally, you could do without raster images and use vector graphics instead (LaTeX pictures, Metapost, TikZ/PGF, and the like); vector graphics also looks much, much better when printed out on paper.

Can you compress those png figures still more, using some tool like pngcrush, or make some of them grayscale instead of color images, maybe that would help?

The figures I have are graphs that I created with MATLAB, I'm not sure how to do it with what you suggested. Also, when I take all the figures out, it still 600 kb.

I think that there is a way to convert it in a way that will make it smaller file.

thanks

I don't have access to MATLAB, so I cannot give you specific advice, but usually a CAS offers several different target formats for graphics export. You might be able to export that graphics as EPS, or as SVG.
If you are using PdfLaTeX to compile your document you will have to convert that EPS file to a PDF: you could either use ImageMagick's convert utility for that, or install a (free) PDF printer on your system for that purpose. There are also SVG to PDF converters, I believe, but ImageMagick's convert cannot do that (at least it could not do it last time I checked).

Also, when I take all the figures out, it still 600 kb.

Well, ok, that means that optimizing the space requirements for those images will not give you much smaller PDFs. So the question is whether you are using any other funny feature of LaTeX that takes an inordinate amount of space. - I've currently no idea as to what that might be, except, perhaps, that you are using a great many different fonts, since (subsets of) the font files have to be stored in your PDF as well.

I think that there is a way to convert it in a way that will make it smaller file.

But note that, these days, 800KB is not that much data. I have here, right in front of me, lying on my desk, a very small memory stick that can store 16GB of data. That's more than 16'000 times the size of your file.

thank for your reply. I know that 800kb it's pretty small, but the problem is that i'm trying to submit an application for something and want to attach a paper that i wrote, and they have a limit of 200kb for each file attached.

Couldn't you split it into four PDFs, each with 200kB?

Wouldn't it be good enough to supply them with with a link to that PDF file, provided you can put it up somewhere on the net?

o.k. i'll think about it,
thanks

Hi,
The way to make the pdf files smaller is to split the PDF files into small number of files, i.e select the page from the large PDF file and split the selected page into new PDF file.
To split the large PDF files you should go for a third party tool like PDF split tool. This tool works for large PDF files and split the PDF files into small PDF files by giving page range as the input to the tool and output will be the PDF file containing the selected page range. There are n number of PDF split tools in the market, but i can suggest you a best PDF tool which i choose from the bundle of the PDF split tools.I use this tool oftenly and my friends and colleagues also use this tool in there daily routine.They are very please from this tool.
You can use SysInfoTools PDF Split. Try this tool and you will surely satisfy with its features and will surely be able to make your pdf files smaller.
