Compressing large files to send via email

This week’s blog post is based on compressing files on your Mac. This is very useful when sending image attachments in emails, as you may or may not know that most email hosts block attachments over 10MB with the rare case of some email hosts, like Gmail, being 20MB. This useful, free and really simple way to compress the picture attachments should help you, if you have had this issue before.

  • Simply open the file in ‘Preview’ from the Applications folder
  • Select the ‘File’ then ‘Print’ option from the top toolbar and save as PDF (some older versions of an OS have an option for ‘Compress PDF’)

  • Save picture on the desktop as a PDF
  • On the desktop version you have just saved, right click (or ctrl click for those who do not have right click enabled) and there will be an option to Compress…..

Select this and it will create a .ZIP version of the picture, which will be smaller.
With multiple pictures you can also do this in the same way by launching ‘Preview’ clicking ‘Tools’ and selecting ‘adjust image size.’ Now you can make the resolution of the pictures smaller, then follow the steps above to make a ZIP’d version.
