Useless, there are better tools online

I bought this for $4 thinking Id save some time over online solutions by not having to upload pdfs in order to compress them. Wrong! Any pdf I try to compress only drops about 4-7% regardless of the setting. In times like these, I wish we could opt for a refund. Save your money and stick with online solutions. BUYER BEWARE.
