Common use cases
iPhones default to HEIC because it stores roughly the same image quality as JPEG at about half the file size, but the format only travels cleanly inside Apple's own ecosystem. Send a HEIC to a Windows recipient, paste one into a marketplace listing form, drop one into a slide deck running on an older Office build, or attach one to a customer-support ticket and the file lands as a broken-image placeholder more often than not. Apple knew this when HEIC shipped as the iOS 11 default in 2017 — Apple's own support documentation says iOS may share HEIC media "in a more compatible format such as JPEG" when the receiving device or app cannot read HEIC, and that fallback is what AirDrop, Mail, and Messages do silently when iOS detects the recipient is on Android, Windows, or any non-Apple platform. The conversion is invisible, automatic, and the same one-step decode-and-encode every browser-based HEIC-to-JPG tool performs (including this one). What this tool does is make that same conversion available outside the Share sheet — for HEICs you've already saved to disk, copied off a memory card, exported from Photos in bulk, or inherited from someone else's iPhone shoot. The output is a folder of plain `.jpg` files, one per HEIC, that any photo viewer, marketplace uploader, slide deck, social feed, or attachment field will accept without a codec install. The conversion happens in the browser tab — the HEIC source never leaves the device, the JPGs materialise locally, and the only network traffic is the page load itself.
