CopyTrans HEIC for Windows: Installation and Use

iPhones and some other cameras save photos as HEIC files, which older Windows setups often cannot open or preview. CopyTrans HEIC is a small Windows add-on built for this problem. This guide covers what it does, how to install it, how to use it day to day, and which details you should confirm for your own version.

Short answer: what CopyTrans HEIC does on Windows

CopyTrans HEIC for Windows is a plugin, not a standalone editor. After installation, Windows can show thumbnails for HEIC photos in File Explorer, open them in the classic Windows Photo Viewer, and convert them to JPEG from the right-click menu. The developer describes it as free for home use, with a paid license required for business use. Check the current license terms on the official CopyTrans website before installing it on a work computer.

Basic setup is the same as for most Windows programs: download the installer from the official CopyTrans website, run it, and follow the prompts. After that, browse to a folder of HEIC photos and confirm that thumbnails appear.

How HEIC and the plugin work

HEIC is a container format based on HEIF. It usually holds images compressed with HEVC (H.265). At similar visual quality, it typically produces smaller files than JPEG, which is why Apple made it the default on recent iPhones. The trade-off is compatibility. Windows needs a decoder before it can display or convert these files, and many older programs never added one.

CopyTrans HEIC provides that decoding as part of Windows itself. This is why it works in Explorer and in programs that rely on Windows image support, rather than only inside its own window. Programs with their own image engines may behave differently. Some can open HEIC without the plugin, and some still cannot open HEIC even with it installed.

Two kinds of detail need different treatment. That HEIC needs a decoder on Windows is a stable fact about the format. Supported Windows versions, the exact wording of context-menu entries, and which apps benefit from the plugin depend on the version you install. Check those in the current release notes or on the product page rather than relying on older guides.

Installing and using CopyTrans HEIC

Installation steps

• Download the installer only from the official CopyTrans website. Avoid third-party download mirrors.
• Close programs that are showing HEIC files, then run the installer and accept the prompts. Windows may ask for administrator permission.
• If the installer asks you to restart Explorer or the computer, do so before testing.
• Open a folder that contains HEIC photos and check whether thumbnails now appear.

Viewing HEIC photos

Once installed, the plugin should let Explorer show HEIC thumbnails, and you should be able to open the files in Windows Photo Viewer. If you use a different default viewer, test it separately. Its HEIC support depends on how that viewer decodes images, not just on the plugin.

Converting HEIC to JPEG

To convert, right-click a HEIC file in Explorer and choose the CopyTrans JPEG conversion entry. The exact label can vary between versions. You can usually select several files at once to convert a batch. After converting, check the folder for the new JPEG files and open a few to confirm they look right. Keep the original HEIC files until you have verified the copies.

Choosing between viewing and converting

• View only: for browsing your own photos on your own PC, installing the plugin is often enough. You keep the smaller HEIC files.
• Convert to JPEG: convert when you need to send photos to someone else, upload them to a site that rejects HEIC, insert them into older software, or print through a service that only accepts JPEG.
• Avoid the problem at the source: on an iPhone, Settings > Camera > Formats > Most Compatible makes new photos save as JPEG. In Settings > Photos, the Transfer to Mac or PC option set to Automatic can convert photos when you copy them over a cable. Both settings affect file size and only apply going forward.

Limits and related questions

Privacy and file handling

CopyTrans HEIC is described as a local plugin, meaning conversion runs on your computer rather than through an upload service. Treat this as a claim to verify, not a guarantee. Read the current privacy policy and installer screens, especially for photos containing people, documents, or location data. Also check whether converted JPEGs keep metadata such as capture date and GPS coordinates. If location privacy matters, inspect a converted file's properties before sharing it.

What the plugin does not cover

• Live Photos: the motion part of an iPhone Live Photo is stored as a separate video file, so converting the HEIC still image does not include the motion.
• HEVC video: HEIC image support does not make Windows play HEVC-encoded video files. Video playback needs its own codec.
• Editing: the plugin opens and converts photos. For cropping, color correction, or export settings, use a photo editor that supports HEIC or the converted JPEG.
• Quality: JPEG uses lossy compression, so converting creates a new compressed copy rather than an exact duplicate of the original.

Do you need it on Windows 10 or 11?

Recent Windows versions can open HEIC through Microsoft's own HEIF and HEVC extensions from the Microsoft Store. Whether these come preinstalled, and whether the HEVC part is free on your system, varies by Windows version and device. If the built-in Photos app already opens your HEIC files and you rarely need JPEG copies, you may not need a third-party plugin. CopyTrans HEIC is mainly useful for the Explorer thumbnails, Windows Photo Viewer support, and quick right-click conversion it adds.

Thumbnails still missing after installation

If HEIC thumbnails do not appear after installation, restart Windows first so Explorer reloads its image handlers. Make sure Explorer is set to show thumbnails rather than icons for that folder. Next, try a different HEIC file to rule out a damaged or unusual file. If the problem continues, check the developer's support pages for known issues with your Windows build. To remove the plugin, uninstall it from the installed apps list in Windows Settings, like any other program.
