HEICPix / HEIC for Outlook
Sending HEIC photos in Outlook email
Your iPhone photos attach fine to Outlook — but the recipient can't open the .heic file on their Windows PC. Convert to JPG first and the photo just works in the email body.
The fix
Drop your HEIC into HEICPix, pick JPG, then attach the converted file in Outlook. Recipients on Windows, Mac, mobile — everyone sees the photo.

Outlook for Windows uses the system's image preview pipeline. Without Microsoft's paid HEIF Image Extensions installed, Windows can't decode .heic — so the attachment shows as a generic file icon and won't preview inline.
Even worse: many corporate IT policies block Microsoft Store installs, meaning your colleagues can't fix it on their end. Converting to JPG once on your end fixes it for everyone.
Inline embed vs attachment
JPG also lets you embed the photo inline in the email body (drag the file into the compose window mid-text). HEIC can't be embedded inline anywhere — Outlook silently converts it to an attachment.
Bonus: strip GPS from work photos
Photos taken on iPhone often contain GPS coordinates of where you took them — your home, your client's office, the cafe meeting. If you're emailing them externally, consider stripping that metadata first.
