I’ve been trying to upload some large files to free PDF compression sites all night. It’s been so frustrating! I tried compressing the files with the Quartz filter on Preview, but the results were horrible. It lost way too much quality and was barely legible! So I figured that I’d try this—couldn’t hurt. I in less than 5 minutes I compress the 3 files that I’ve been struggling with all evening! I’m in love! The quality is SO much better than the Preview method! Thank you, thank you, thank you!
