Take a photo on an iPhone and, depending on your settings, you get a HEIC file: smaller, better-compressed, and completely unreadable to Windows by default. Double-click it and Photos offers to fetch a codec, or simply shrugs. You cannot paste it into an email, upload it to many websites, or open it in older editors. The format is better; the compatibility is worse.
So iPhone owners on Windows end up converting HEIC to JPG, a task that should not be complicated and becomes a small industry of sketchy converter websites if you do not know the good tools. Here are the good tools, with trade-offs, including one that requires no installation at all.
One note first: JPG loses the quality and size advantages of HEIC, since it is the older format. Converting is a compatibility move, not an upgrade.
CopyTrans HEIC: drag, drop, done
CopyTrans HEIC installs a codec plus a right-click converter. Once it is on your machine, HEIC thumbnails appear in Explorer like normal images, and converting is a matter of selecting files, right-clicking, and choosing to convert. Batch conversion of a whole folder works too, and your photos stay on your machine.
The strengths:
- After install, HEIC files simply behave like images in Explorer and Photo Viewer
- Right-click batch conversion with no interface to learn
- Free for personal use, with a paid license for business use
The trade-offs: it is Windows-only by nature and it is another program installing itself into your system, which some people reasonably dislike. The free tier is personal-use only. And a codec quietly extends your system rather than living in its own box, so if you are the type who keeps a lean machine, factor that in.
iMazing Converter: simple and standalone
iMazing is known for iPhone backup software, and its free converter tool does one thing: turn HEIC into JPG (and back), and convert video to MP4, with drag-and-drop simplicity. It is a standalone app, so nothing burrows into your system.
The strengths:
- Genuinely simple: drag files in, pick the format, click convert
- Batch conversion, so a hundred photos take one operation
- Free, standalone, and from a company with a real reputation in the iPhone space
The trade-offs: it is a hand-rolled tool from a company whose main product is something else, so do not expect advanced options. Quality and compression settings are limited. And like any desktop app, it is one more thing to install and eventually uninstall. For most people converting vacation photos, that simplicity-versus-control trade lands on the right side.
The Microsoft Store codec: make Windows do it
The straightforward fix is the HEIF Image Extensions package in the Microsoft Store, which lets Windows Photos open HEIC natively. There is also a separate HEVC video extension that some HEIC files need for their embedded content, and that one costs a small one-time purchase.
The strengths:
- Photos app just opens HEIC afterward; no conversion step at all for viewing
- Official Microsoft software, no third parties involved
- Works for viewing and for Windows' own editing features
The trade-offs: the HEVC piece costs a small amount, which is a strange tax on opening your own photos, and plenty of people balk on principle. It also solves viewing more than conversion: if a website or an older app demands a JPG, you still need to export one. And Store apps occasionally fail to install for reasons nobody can explain. When it works, it is the cleanest option; when it does not, it is the most frustrating.
BrowserStay Image Converter: nothing to install
If this is a one-time job or you are on a locked-down machine, BrowserStay's image converter does HEIC to JPG in the browser. Drag the files in, get JPGs out, no account, no install.
The strengths:
- Works anywhere Windows runs a browser, including work machines where you cannot install software
- Fast for typical batches of personal photos
- Nothing persists on your machine afterward
The trade-offs: browser tools are not the right answer for converting thousands of files regularly, and for large batches a local app will always be faster and less tedious. If you convert HEIC weekly, install a proper tool; if you convert it twice a year, the browser is the sensible choice.
Which one should you pick?
- Convert photos often, want it to just work: CopyTrans HEIC
- Occasional batches, prefer a standalone app: iMazing Converter
- Want native viewing, okay with a small Store purchase: the HEIF extension
- One-off job, no installs allowed: BrowserStay's image converter
Whichever you pick, keep your HEIC originals somewhere safe. They are the smaller, better files; JPG is just what the rest of the world can read.
