iMazing HEIC Converter is one of the first free tools that showed up after Apple made HEIC its default photo format. You open the app, drop your HEIC files or a whole folder onto the window, pick JPEG or PNG, and click Convert. There is no account and nothing to configure before you start, which is a big part of why casual users like it.
The naming can confuse you, so it helps to be clear. The standalone tool is what most people mean by "iMazing HEIC Converter," and DigiDNA also bundles the same engine inside the full iMazing iPhone manager under a Tools menu. The vendor later renamed the standalone app to "iMazing Converter 2" when it added video conversion support, so a fresh download today may carry the newer name for the same core job. On iMazing's own product page, the app is described as free for Mac and PC, converting photos from HEIC to JPEG and videos from HEVC to MP4.

One detail matters for privacy. Conversion runs on your device, so nothing is uploaded and no internet connection is needed. If you want the full background on the format itself, Adobe notes that a HEIC file can use about half the space of an equivalent JPEG, which is exactly why iPhones ship in HEIC and why so many people end up needing a converter for Windows.

Here is what the tool actually gives you.

The Mac listing gives a sense of how light the app is. On the Apple App Store, the version at the time of writing is 2.0.13 at about 14.6 MB, and the store page shows no rating overview because it has not received enough ratings yet. Treat any star numbers you see on affiliate blogs with caution, since the official listings do not display one.

On price there is little to weigh. The standalone converter is free, with no premium plan and no account. It is a free companion to the paid full iMazing suite, not a trial that nags you to buy. What you pay is really in the friction, not in dollars, and that friction shows up mostly on bigger jobs.

We did not run our own timed benchmark for this review, so we will not quote a speed number as fact. No neutral, independent speed test of the tool exists either; the "finishes in under 30 seconds" figures you find on other review blogs come from sites that sell competing converters, so we treat them as marketing, not data. The vendor says the rebuilt app should "chew through thousands of media files at a time," which is its own claim to prove, not ours.
Where the picture gets mixed is reliability. Across several review write-ups, the single most repeated complaint is that batch conversion stalls or fails partway through a folder with no clear error. One competing-vendor review flatly states that "many users complained about the crash converting issues." That source sells a rival tool, so weigh it with care. Even so, the same complaint shows up often enough to note fairly. On the Aiseesoft write-up, the crash-on-convert theme is one of the headline gripes. For a free tool this is not a dealbreaker; for a folder of 800 vacation photos it is worth knowing before you rely on it.

The reliability complaint has two distinct shapes, and it helps to separate them. The first is the batch itself. Users report that a folder conversion freezes midway, or that some perfectly valid HEIC files get skipped or rejected with nothing on screen to explain why. On a small handful of photos you rarely see this. On a few hundred, the odds climb, and there is no pause-and-resume, so you often restart the whole job.

The second shape has little to do with the converter. It comes from Windows itself. HEIC support on Windows is patchy, and photos can throw a "We can't open this file" error even after the official HEIF Image Extensions are installed. A Microsoft Q&A thread shows how tangled this gets. It is a broad Windows-and-Photos gap that lands on whatever tool you happen to be using, no matter which converter you picked, so it reads as "iMazing not working" when the real fix is on the Windows side.

Start with editing. iMazing converts, and that is all. There is no way to crop or resize a photo on the way out, so if you need a batch of resized JPEGs you convert first and then reach for a second tool. Reviewers also note it keeps no history of what it already converted and cannot pause a running batch to drop a few images.
Then there is metadata drift. Converting HEIC to another format can lose the original capture date, which quietly reorders your library by conversion time instead of the moment the photo was taken. On the MacRumors forums, users chasing this exact problem found that even a dedicated shortcut "can't reassign initial timestamp for created images." It is a wider conversion pain, but it bites here too.

The last gaps are workflow ones on Windows. There is no right-click entry in File Explorer to convert a HEIC without opening the app, and no command line, so you cannot script a nightly job or a watch folder. For a quick one-off that is fine. For anyone converting HEIC every week, launching it by hand each time gets old. If Windows refuses to show your photos at all, the fix for when Windows Photos won't open HEIC covers the extension side of the problem.

SoftOrbits HEIC to JPG Converter takes the opposite approach on the two things iMazing leaves on the table. It runs a reliable batch and lets you edit before you save. It converts HEIC to JPG or PNG using all your CPU cores, so a full folder finishes as one job instead of stalling halfway. And it lets you rotate, crop, smart-crop, or resize a photo before conversion, which iMazing cannot do at all.

It also fills the workflow gaps. A built-in HEIC viewer lets you preview before and after. There is a right-click Explorer entry that converts without launching the app, a command line for automation, and a watch-folder option that converts files the moment they land. Full color-profile, HDR, and wide-gamut handling keeps the quality that HEIC captured. You can also rename output files by capture date, so your chronology survives the conversion. SoftOrbits HEIC to JPG Converter is a free download with a trial, and the license is paid. The honest trade against iMazing is money for reliability, editing, and automation. You can grab the heic to jpg converter download for Windows and try a batch before you decide.

We are honest about the trade-offs. Our tool is paid once you pass the trial, while iMazing is free forever. It runs on Windows 10 and 11 only, with no Mac or mobile build, so an iMazing user on a Mac stays with iMazing. And it is a focused converter, not the broad iPhone-management suite the iMazing brand is known for. If you convert HEIC often on a Windows PC, though, the batch and editing depth are the whole reason to switch.

Verdict: Choose SoftOrbits HEIC to JPG Converter if you convert HEIC regularly on Windows and want reliable batch plus editing. Stick with iMazing for a free, occasional job or if you are on a Mac.

iMazing HEIC Converter vs SoftOrbits HEIC to JPG Converter

Here is the side-by-side on the points people actually weigh. The facts below come from each vendor: iMazing details from imazing.com and the app stores, and SoftOrbits specs from our own product data.

We would not push everyone to a paid tool. iMazing genuinely wins in a few real cases. If you cannot spend anything, free and functional beats paid and better. It runs on macOS as well as Windows, so a Mac user has no reason to look at a Windows-only converter. And for someone who converts a dozen iPhone photos once a month, dropping them on a window and clicking Convert is genuinely less hassle than learning a deeper tool. The rebuild also closed the old "no quality control" complaint, so that mark against it is now mostly historical rather than a current fact. If your only need is converting a few shots to send to a friend, iMazing does that well and asks nothing in return.

There is no reason to treat iMazing HEIC Converter as unsafe. DigiDNA is a known developer, the app is listed on both the Microsoft Store and the Apple App Store, and there is no account to create or personal data to hand over. The strongest safety point is that conversion is local. Your HEIC photos are processed on your own machine and never uploaded, which is a real privacy edge over browser-based converters that ask you to send files to their servers. If you are converting private photos, a local desktop tool, whether iMazing or a Windows alternative, is the safer path than any upload-and-download web service.

iMazing is not the only option, and it is worth knowing the field before you settle. Here is what else we looked at and why each one landed where it did.

• CopyTrans HEIC is a free Windows-only tool that adds HEIC thumbnails and preview to File Explorer and a right-click "Convert to JPEG," but it outputs JPEG only, with no PNG and no batch quality slider.
• Apple's "Most Compatible" camera setting, under Settings then Camera then Formats, makes your iPhone capture JPEG instead of HEIC going forward. It stops the problem at the source but does nothing for the HEIC photos you already have.
• Generic online HEIC converters need no install and run in any browser, which is convenient, but they require uploading your personal photos to a third-party server, so you give up the offline, local processing that both iMazing and desktop tools keep.
• If PNG is what you actually need rather than JPEG, a dedicated HEIC to PNG converter keeps transparency and detail that JPEG flattens.
• On a plain Windows PC without iCloud, the step-by-step to convert HEIC to JPG on Windows walks through the whole path.
