Here is the real feature set. Each item is cross-checked against the official page and independent reviews rather than pulled from marketing copy alone.

• HEIC thumbnails directly in Windows Explorer. The plugin generates real previews, and your photo folders stop showing blank icons. The WidsMob review confirms this behaviour.
• Full-size viewing through Windows Photo Viewer or the Photos app. Double-click a HEIC file and it opens like any native image once the plugin is installed.
• Right-click "Convert to JPEG with CopyTrans." This is the core action. You select the photos, then right-click and convert. The MobiKin review confirms the same two-click flow.
• Batch conversion, capped at 100 images per operation. You can select a group and convert them together, but not more than 100 at a time.
• EXIF metadata preserved. Date taken and geolocation carry over to the converted JPEG, per the Apeaksoft review.
• Microsoft Office integration. CopyTrans says you can insert HEIC photos directly into Office apps like Word, PowerPoint and Outlook (Office 2010 and later).
• Direct printing of HEIC images without converting first.
• Offline, local conversion with no cloud upload, according to CopyTrans.
• Integration with third-party image viewers, plus Citrix and Terminal Server support for enterprise setups.

One inconsistency worth flagging. FileHorse's listing text claims CopyTrans HEIC can output "JPEG or PNG," but the official how-to and every other review we checked say output is JPEG only. We treat the PNG claim as a listing error, not a feature.

This CopyTrans HEIC review found the core plugin genuinely free for personal, non-commercial home use, and that is a big part of its appeal. But the freemium wedge shows up fast. Per CopyTrans' own Terms and Conditions, any commercial or corporate deployment of the free version violates the license. Businesses must buy a CopyTrans HEIC Business License, priced by number of PCs or server users, including one year of use with email support and updates. There is a stated 20% discount for non-profits and schools, and a broader "CopyTrans 7 Pack" bundle license. Crucially, there is no public price list, so you email [email protected] for a quote.

The batch limit is the headline performance constraint.

CopyTrans' own support article confirms the 100-image cap and states that the free build "will no longer be updated." For users who need more, the vendor points to a paid CopyTrans HEIC Pro tier with "limitless conversion," and for personal users it recommends the separate CopyTrans Studio product that converts "HEIC to JPEG, PNG and PDF with no limit." Both are quote-only or paid, so the moment you have a big library the free tool stops being the answer.

On raw performance, the tool is quick for a dozen photos. The problems appear with volume and control. There is no way to set JPEG quality or compression, so you take whatever the tool decides, and output stays JPEG only. Large libraries are painful. As one review puts it, if you want to adjust photo quality or convert over 100 images together, the tool "cannot help or is time-consuming," per the Coolmuster review.

For step-by-step visuals, CopyTrans links a video on its official how-to guide. Note that the same support page now nudges readers toward CopyTrans Studio as the recommended tool going forward, another sign the standalone plugin is on its way out.

The single biggest gap surprises people. CopyTrans HEIC only converts HEIC files that came from an iOS device, so if your HEIC came from a digital camera it will not convert. The WidsMob review confirms the tool "only works for HEIC images taken by iOS devices." Apeaksoft notes it "does not support Canon HEIC files," and Softonic's own cons list repeats "Doesn't support Canon HEIC file types." The "HEIC converter" label is really "iPhone HEIC converter."

The other limits stack quickly.

• 100-image batch cap. Fine for a phone dump of a few dozen shots, but a wall the moment you have a real library. If you routinely need to batch-convert hundreds of HEIC files, this tool cannot do it in one pass.
• No quality or resize control. It is a converter, not an editor, with no quality slider and no way to resize or crop before saving. WidsMob's comparison specifically credits rival tools with image rotation and resizing, capabilities CopyTrans lacks.
• JPEG-only output. No PNG or PDF, and no TIFF, from the free plugin.
• No command line at all. No source mentions a CLI or scripting hook, whether official or third-party. It is a manual, right-click GUI tool only.
• No macOS version. Confirmed across the Hitpaw and Coolmuster reviews. This is expected, since Mac handles HEIC natively, but it is worth stating.
• Antivirus false positives. The Coolmuster review reports some AV engines flag the installer, sometimes forcing users to temporarily disable protection, even though download portals like Softonic report a clean scan. MobiKin separately reports occasional stability issues and a 90-degree rotation bug during batch conversion, a single-source claim to treat as anecdotal.

Add the product-line confusion, where FileHorse flatly states "This program is now CopyTrans Studio," and you have a free tool that works for its narrow job but is visibly being retired.

If you hit any of the walls above, a dedicated converter is the fix. The workflow difference on a large library shows it clearly.

The SoftOrbits HEIC to JPG Converter is built for the exact cases where CopyTrans stalls.

• No 100-image limit. It runs batches across all your CPU cores, so hundreds or thousands of photos convert in one job. A 4,000-photo library finishes in a single pass instead of 40 manual chunks.
• Converts any HEIC, not just iPhone. Camera HEIC that CopyTrans refuses converts fine here.
• Real quality and size control. Set JPEG quality, then resize or crop with an optional smart crop. These are the editing controls CopyTrans has none of.
• HDR and wide-gamut handling, plus a built-in HEIC viewer. You are not stuck with the Windows Photos app.
• Command line and watch-folder automation. Point it at a folder and it converts new HEIC files automatically, which is genuinely useful for a repeatable workflow.
• Explorer integration and 100% local processing. Nothing leaves your PC.
• Output beyond JPEG. You are not locked to a single format.

To be fair, the SoftOrbits HEIC to JPG Converter is paid software. There is a free trial, though it is not permanently free like CopyTrans. If you only ever open a handful of iPhone photos on your PC, paying for a converter is overkill, and CopyTrans' free plugin is the sensible choice. The paid tool earns its price only when scale and source variety matter, or when you need quality control and automation. You can see the full feature list on the HEIC to JPG Converter landing page.

This CopyTrans HEIC review's verdict is not that one tool is bad. CopyTrans HEIC is a fine free preview-and-convert plugin for casual iPhone users. But if any row above matters to you, especially the batch cap and camera HEIC, or the lack of quality control and automation, then the SoftOrbits HEIC to JPG Converter covers exactly the gaps CopyTrans leaves open. That is why it is the stronger pick for anyone converting HEIC at real volume.

This review is not going to pretend CopyTrans HEIC is useless. That is what thin affiliate pages do, and it is dishonest. For a large share of people, CopyTrans HEIC is genuinely the right tool. If the situation is "a few iPhone photos copied to a PC, just to see the thumbnails and once in a while turn one into a JPEG," this free plugin does that in seconds with no money spent and no app to open. The Explorer thumbnail integration in particular is clean and low-friction.
Stay with CopyTrans HEIC if your HEIC always comes from an iPhone and you never convert more than about 100 photos at once. You should also not care about setting JPEG quality or output format, and you should not need a Mac version or automation. In that lane it is hard to argue with free. The one caveat is longevity. With the vendor steering users toward the paid CopyTrans Studio and the plugin frozen, do not count on new features.

Here is what each does and where it falls behind.

• Windows Photos with the HEIF Image Extensions add-on opens HEIC natively in Windows 11 once installed. The extension is a paid add-on for many users, and Photos still offers no batch conversion and no quality control, so it is viewing rather than a workflow.
• Online HEIC converters run instantly in a browser for free with nothing to install. They also upload your photos to a third-party server, a real privacy problem for personal images, and usually cap file count and size, which makes them fine for one throwaway image and wrong for a private library.
• iMazing HEIC Converter is a free desktop drag-and-drop tool for Windows and Mac that handles any HEIC source with basic quality control. It has no automation and none of the resize or crop depth of a paid tool, so it is a decent free middle ground rather than a scale tool. Our iMazing HEIC Converter review has the full breakdown.

If your target format is PNG rather than JPEG, for transparency or lossless quality, see our HEIC to PNG Converter, since CopyTrans HEIC cannot output PNG at all.

• Softonic listing Store rating of 3.8/5, with Canon and JPEG-only listed as cons.
• Apple Community thread Reports that auto-conversion of HEIC to JPG on PC transfer no longer happens despite the "Most Compatible" setting.
• Apple Community thread Trouble copying and opening HEIC files on a Windows computer.
• BleepingComputer forum thread Users asking whether the plugin is safe to install.
• MajorGeeks listing Editorial rating of 5/5 across 13 votes.
• Free-codecs reviews User rating of 4.5/5 on the standalone HEIC build.
