Won't Windows recipients struggle with HEIC?

Possibly - ironically the format that solves the Mac side needs the HEVC Video Extensions (a Microsoft Store add-on) on Windows 10/11. If your newsletter audience is mostly on Windows PCs, convert the output through HEIC to JPG before emailing; if it's iPhone-and-iPad heavy, ship the HEICs as-is and enjoy the smaller attachments.

Supported devices and browsers

heic.now is a regular web app — it works on anything with a modern browser:

Desktop: Chrome, Firefox, Safari, Edge, Brave, Opera, Vivaldi — last two major versions of each.
iPhone / iPad: Safari 14+ and any WebKit-based browser (Chrome on iOS uses WebKit too).
Android: Chrome, Firefox, Samsung Internet, DuckDuckGo browser — anything from Android 8 onwards.
Linux / Chromebook: any modern browser.

No app install, no plugin, nothing to side-load. If your browser can open this page, it can run the converter.

Working with phone photos

iPhones produce HEIC by default since iOS 11; modern Androids may produce HEIC or JPG. Both work in heic.now: drop the file straight from the camera roll into the dropzone and we'll handle it. The same goes for live photos (we extract the still frame), burst-mode photos, and screenshots.

If your iPhone is set to Most Compatible in Settings → Camera → Formats, photos are already JPG. Otherwise they're HEIC — use our HEIC to JPG converter to get a universally-compatible JPG.

Differences across platforms

The conversion itself is identical on every platform — the work runs on our servers, not your device. The only differences are at the edges:

iOS Safari sometimes asks twice before letting a site read files from Photos. Tap Allow when prompted.
Android Chrome exposes the gallery via the system file picker — pick from "Files" or "Photos" depending on where the image lives.
Desktop supports drag-and-drop from your file manager and from other browser tabs.
