How to reduce the PDF file size of MPDF

Question

I am creating a 15 to 20 pages PDF using MPDF on Form Submission. PDF file size comes around 2.5MB. Is there a way to reduce the file size below 1 MB?

Since the SetCompression() default value is True, I tried setting this to False and checked the file size of PDF. There is no change in file size. I tried SetCompression() and still no luck. I even reduced the PDF to 3 pages, size sill comes around 1.5MB. Is there any other way to reduce the file size?

Can someone help me with this?

Below is the link for the code which I used.

Answer 1

Compress your images.

Image raven_tours_treks_logo.jpg in your code is 619,75 kB. The file contains it twice - by compressing it correctly, you can save a megabyte or so.

raven_tours_treks.jpg has almost a megabyte. It can safely be reduced to 80kB or so - another megabyte saved.

Answer 2

Try whether pdftk compression significantly reduces the size of your PDF file.

pdftk file1.pdf output file2.pdf compress

If you are satisfied with the results, I can enhance our object-oriented PHP pdftk wrapper with the capability to compress PDF files.
