Currently there is no file size limit. However, larger files will take more time to upload. Please reduce images or compress larger files to shorten this file upload time.

Images can be reduced in size by the following methods:

• Reduce the size of the image in an imaging program
• Reduce the resolution (e.g., from 300 dpi to 150 dpi)
• Optimize and compress the PDF

When reducing the file size of your PDF, first check the size of the graphics that are used in the document. To ensure a smaller file size, we recommend graphics be reduced to 150 dpi and charts and graphs be reduced to 72 dpi.In Acrobat?, depending on what version you are currently using, there is usually a way to optimize or reduce the file size through the file menu. Check your user manual to determine the best method for file size reduction in your version of Acrobat?.
