How to compress pdf file
Hi all,
Is there an easy way to compress pdf file? I don't have pdf-compressor installed. Existing pdf size - 9.5MB I need to compress it to about 3MB I used the online pdf compressor http://www.ilovepdf.com/compress_pdf compressing it to 4.6MB. But I couldn't compress it again, the second time. I have "convert" here. Please help. Thanks Regards satimis |
what is in this pdf ????
text ONLY ? a bunch of png or jpg images ? what ? i find that xz compresses the most Code:
xz -z9kv Whatever.pdf |
Quote:
It is completed "Form", scanned satimis |
so a image
is it a tiff? jpg? png? windows bmp ? what ? for images reduce the size or if it is a black and white form there is NO need for it to be a Red Green Blue image convert it to grayscale or a 8 bit gif |
8bit png usually compresses best, but depending on the quality/contrast of the original, jpg can be better.
so, edit the image in gimp, export to pdf? if you use png, pngquant is really helpful with compressing! |
Hi all,
Thanks for your advice. The pdf file was received from another company not created/scanned by me. I have no way to recreate it. The file consists several pages. Can I split it into 2 pdf files? satimis |
ok.
search indicates that this can be done with fairly standard linux programs like gs (ghostscript) or convert (imagemagick). |
Good luck. It depends entirely upon what the producer of the file did (or didn't do).

@John VV was trying to steer you in the right direction. If you really need to reduce the size then you need to extract the image files and reduce their size to the smallest, but still legible, size. Then recreate the pdf using those smaller images. That will give you a smaller pdf. There are numerous tools to recreate a pdf from images.

Having read this I thought it was rather enlightening. I appreciate you finding the time and energy to put this content together. I once again find myself spending a lot of time both reading and posting comments. But so what, it was still worthwhile!.

Tradekare, hello and welcome to LQ.

It's a bit cumbersome with multi-page PDFs, but I've done this with *.PDFs that were too large in dimension so I could post them on a website:
I do know that rar compression program has the capability to splitting files into multiple parts during compression, but it requires a small registration fee. It's very popular on Usenet because of this feature. There is a Linux version available; it's strictly command line. |
