Why HEIC photos cause trouble
Expense apps, client portals and older Windows computers often reject HEIC files or show them as unknown attachments. Converting to JPG makes receipts and document photos open everywhere.
Going straight to PDF
If the photos are receipts or documents, you probably want a PDF in the end. JPG to PDF reads HEIC directly and puts each photo on its own page, upright.
Other ways to open HEIC
- On a Mac: open the photo in Preview and use File > Export to save a JPEG, one file at a time.
- On Windows: Microsoft's HEIF Image Extensions add HEIC support to the Photos app, but other programs and web uploads still often reject the files.
- On the iPhone: sharing a photo by email or AirDrop to a non-Apple device often converts it automatically, but not when you copy files over USB or sync them.
Converting here handles a whole batch in one go, on any computer, and nothing leaves your device.
Receipt photos for the books
For expense reports and receipt archives, keep receipts flat, well lit and cropped to the paper. JPG at the default quality keeps small print legible at a fraction of PNG's size. Name files with the date and vendor, like 2026-03-14_officedepot.jpg, so they sort in order and match the card statement quickly.
