Questions and answers
Why do iPhones save HEIC instead of JPG?
Apple uses HEIC because it stores smaller photo files while keeping strong image quality. That reduces storage pressure on phones and cloud backups.
When should I convert HEIC to JPG?
Convert when you need broad compatibility for websites, forms, Windows software, document attachments, or clients who may not support HEIC.
Does converting HEIC to JPG reduce quality?
Any format conversion can change output quality, but for everyday sharing and uploads the practical tradeoff is usually acceptable.
