These options, and more, are fully documented on their website. From memory, GMail provides over 10MB per email.
#RESIZE PDF FILE PDF#
You could also split the PDF file into pages with pdftk, as suggested in his edit, or split the archive and recombine at the other end.ĢMB is also a rather small attachment limit, you may want to look into other email providers. This brought the file size down to 0.43MB on that test PDF (reducing the JPEG compression quality has a much more drastic effect).
#RESIZE PDF FILE ZIP#
If you're still tight for space, especially for the multipage PDFs, you could compress further by adding the files to a ZIP (or other) archive.
On your example PDF, this makes the small print at the bottom pretty much unreadable, though. If you want a smaller size (both of the file and of the image/PDF), you can use -resize #%, e.g. Using the Dialog Go to Pages Tab > Resize Pages on the toolbar Choose the page size settings and values for the document Click OK to apply the settings. These options bring your 1.7MB sample down to 0.5MB, while keeping it readable. Setting it at 20, it looks almost as good as the original (a little fuzzier and the small text at the bottom is a little hard to read, but it was originally anyway). JPEG compression should either auto choose a level or default to 92 on a scale of 1 to 100 with 100 being the best. It looked alright at 150, and was a little smaller, but if you want to cater for a range of PDFs 200 should work. By setting it higher we can get a higher resolution and therefore acceptable quality. This worked quite well for me: convert -density 200 -compress jpeg -quality 20 test.pdf test2.pdfĭensity defaults to 72 DPI. I've done some testing on your provided sample PDF. While mogrify will convert in place, I recommend you use convert so you can keep the originals in case of accident. To convert PDF files with ImageMagick, you need to have GhostScript installed. $ mogrify -rotate 270 -density 300x300 -compress lzw pg_*.pdf Adding in the compression option helps keep the overall size of the PDF smaller, with no loss in quality.įor multipage PDFs, you may want to use pdftk, then use mogrify from ImageMagick to convert each page in place: $ pdftk in.pdf burst
The density parameter is important because otherwise ImageMagick down-samples the image (for some reason). You can also use the compress option (there's an example here): Rotate a PDF $ convert -rotate 270 -density 300x300 -compress lzw in.pdf out.pdf I've never used it personally, but you can try to play around with that. ImageMagick supports PDFs and has a resize option with its convert tool. I'm suggesting a command line tool here, which can be easily batched with loops in built-in scripting languages in Windows, Linux, OS X, etc.
