Use this guide when an email bounces because an attachment is too big, a website upload rejects your file or you need to send many photos at once. Keep the original files safe, as you will make smaller copies.
Step by step
Check the limit and the file size
Find the size of your file by right-clicking it and choosing Properties on Windows or Get Info on a Mac. Check the limit for where you are sending it: email providers and upload forms state a maximum, and the recipient's limit can be lower than yours. If you are only slightly over, compressing is quick; if you are far over, skip to sharing by link in step 6.
