Review by T2Muser

Instantly reduced my PDF to 25% of original size - Despite the recent negative review from someone who wasn't able to save a converted file, I had absolutely no problem with this app. I needed to compress and email a PDF contract that was over 24MB in size while keeping the quality good enough to print clearly. I didn't even need to read any help files; the controls were very intuitive and provided an instant preview of the results when any setting was changed. I easily converted the doc down to 6MB in size without any noticeable loss to print quality. If this is what you need, I highly recommend this app.

Review by LostMonies

Did Not Work For - I place a 4.3 MB pdf file in the app and it came out the same size 4.3 MB- NO reduction??. Not quite sure how they other people got it to work but I wish I had my $2.99 cents back. Save your pennies.Wish the creator would post why it does not work when it fails; would be helpful: Trouble Shooting.

Review by FredsterHere

Excellent! - I scanned a 10 page document of text and it was 44 megabytes. Preview app just wasn’t able to give me good quality at all. I even started to test the ColorSync tool. This has been challenging on Mac for as long as I can remember and apps have been way too pricey. This app did the job perfectly. In less than a minute I figured our how to change the document to gray scale, export, and magically my document is only 1.3 megabytes. Worth every penny!

Review by sportster002

Works like a charm! - I have been struggling to find a way to reduce the size of scanned documents while maintaining legibillity of text. I could not figure out how to do it with the OS X built in tools. I tried to compress with Preview and even Color Sync Utility. The files would compress but the text would be illegible, or the text would remain legible but the compression was too little. This neat little app did the trick. Well worth the 3 bucks! Thanks PDFOptim!

Review by Enderlyn

Greate app. Worth well more than its price tag. - This app saved my bacon. I had 168 PDF files that totaled 36GB in size and needed to reduce them drastically in size while still maintaining a reasonably high quality for printing. PDFOptim did the job in about 20 minutes, reducing the space required to just 370MB for all 168 files. This app saved me a ton of time.

Review by FrizzleFryBen

Super easy and quick - On first open, I was able to quickly convert 9 print res PDF’s into versions for email attachments. Saved on average around 35% and they weren’t even image heavy. Love that I can see original and conversion proof side-by-side while making adjustments. I tweaked it exactly where I needed the dpi and jpg quality, saved the settings and now I’m good to convert the other 200 or so with little effort. This will stay in my essentials toolbox! If you’re unconvinced, they have a lite (trial) version that adds a watermark…but will show how well it works. $2.99 for full version is a no-brainer.

Works Great 84% File Size Reduction - I took a 15 mb PDF of a multi-page text document down to about 1.5 mb. The interface is well done, and easy to use. The app works great.
