Hit Gold on My Second Try ,

Excellent Results. Excellent Price

I compared Squeezer to Cisdem, NX Power, NCH and PDF2GO compressors by optimizing three documents using each of the programs, then giving them they eyeball test. In other words, this wasn’t heavy science, just what “looks better". Squeezer beats them all. It offers the best combination of maximum quality and minimum size. One of the others can make slighter smaller files, but they’re illegible, a big disadvantage in my opinion. One of the others can make a file as small and as legible as Squeezer, but it has to drain out the color to do it. Squeezer keeps the color and the legibility at the minimum size. I actually bought one of the other compressors awhile ago at a much higher cost than Squeezer. It’s now retired, and the cost written off to yet another learning curve. Save yourself time and money; get Squeezer.

Use it all the time, super simple

It does exactly what it promises! It allows you to choose the resolution of the “squeezed” file. The lower the resolution, the smaller the file size, but the files look perfectly fine even at the lowest resolution settings in my experience. This helps a lot with shrinking the file size of scanned documents. Some scanners will save the file as a PDF, but each page will be several MBs in size as if it were a JPEG or some other image file which takes up a lot of space. I have to send a lot of PDF documents for work and some recipients can’t receive very large attachments by email, so this really comes in handy. Having a smaller PDF file also saves space on your computer and generally makes it faster to open. I have this on my dock and use it all the time.

WOW! As a graphic designer I am blown away! 320MB to 5.4MB with perfect quality

As a graphic designer I have tried about every pdf size reducer available online and in my graphic apps. Adobe pdf isn’t capable of reducing files like this, no online version can reduce it THIS much. I literally discovered a site earlier today that smashed my 300MB file in 6MB, and my 220MB into 870KB, but you can only use their service twice an hour without paying $6/mo. I didn’t want to pay so downloaded this and it’s just as good but I only have to pay $5.99 once not every month! it turned 320MB file to 5.4MB with no quality loss - I am blown away. I had to leave a review immediatly because this is the best compressor I have every used. Would recommend to anyone!
