Compress Photos to Send Through Outlook
Get under Outlook's attachment size cap without splitting your email.
Outlook and Office 365 cap attachments at around 20 MB, and a few phone photos blow straight past it. Compressing them lets you attach more in a single email.
Set a maximum size and quality, add your photos, and download lighter versions ready to attach — with the date taken preserved. It runs in your browser so you can batch a whole set at once.
Frequently asked questions
What's Outlook's attachment limit?
Usually 20 MB for Outlook.com / Office 365 and sometimes less on corporate servers. Keeping your total well under that avoids bounce-backs.
