HEIC from iPhone — how to open and convert to JPG

Apple saves photos in HEIC by default — smaller than JPG at the same quality. Problem: Windows without an extension, older apps, and many services don't support HEIC.

Solution: convert HEIC → JPG or HEIC → PNG in Toolando.tech before emailing, uploading, or printing. You can also set iPhone to "Most Compatible" (JPG) in Settings.
