v4.0
- Major update with the only solution to optimise PDF vector graphics. Added new 'Optimize graphics' compression option which can remove superfluous information to reduce vector graphics heavy PDF. Increase in optimize graphics from 'Level 1' to 'Level 5' reduces output PDF file size less to more respectively. Choose appropriate Optimize graphics level to balance file size and visual fidelity. Choose Optimize graphics option 'None' to avoid vector graphics optimization.
This option is very useful when PDF content mainly consist of high precision vector graphics. This option removes such superfluous information, thereby reducing the size of your PDF files. Usually PDF drawing, note-taking and PDF markup apps creates large vector graphics heavy PDF files on iOS and macOS. Now such PDF files will be compressed efficiently using PDFOptim Optimize graphics option.
- Now PDFOptim for Mac is macOS universal app, fully optimised to run natively on both Apple Silicon Mac and Intel-based Mac computers.
- Full compatibility with macOS Big Sur.
- [Fixed] File specific issue taking longer time to compress.
- Minor bug fixes and improvements. Thank you all users for your feedback :)
