How to less pdf size without losing any quality?

My 30-page PDF report is over 50 MB, but every compressor I try makes the images completely blurry. How can I reduce the file size significantly while keeping the text and graphics sharp?

had the same thing last month. if you still have the original, i just resize the pics in word or whatever you made it in before exporting the pdf. tbh that keeps text and graphics sharp and the size drops a lot. those compressors always make mine look terrible.
