Click Audit space usage to check the space usuage for specific document elements and decide which items needed to be optimized; 2. I have about 50-60 pdf files images that are 1.
Batch Processing You can take advantage of Bash to quickly do batch processing of many images. You simply need to list several input files before the output file, i. Vishnu Kumar I'm glad you asked. The compression settings are also advanced, including custom options for algorithms and image types. But I see that converting the full document requires again a lot of memory.
