How can I reduce the file size of PDF files in C#?

Question

Is it possible to reduce the file size of a PDF?

I have couple of things saved in DB as PDF, image, docs, etc. saved as base64, but mostly PDFs and images.

I am able to reduce/scale down images, but would it be possible for PDFs too?

This is for a mobile application. I can compromise on quality (which I am doing with images).

Edit

Can't say what's in the pdf, depends on the client, I guess there is no easy/direct way to reduce the size of pdf.

What's your thoughts on compressing the PDF and decompressing at mobile side? Will it have any effect on reducing the size?

Try converting the pdf into images page at a time, and cache this, sending the image down to the mobile app — Don

PDFs contents may or may not already be very condensed. You should analyse your PDFs first. — mkl

I am not sure why this question was down voted. If they could explain, I would be able to ask good question next time. — Vineeth Vijayan

It mainly depends on your PDF:

You can remove embedded fonts

You can reduce images quality

You can optimize resources if duplicated (if source is iText it isn't a remote option)
