How to Choose a HEIC Converter

A practical checklist for choosing a HEIC converter: output formats, metadata, color, batch handling, privacy and compatibility with your system and apps.

HEIC is the image format many phones, especially iPhones, use for photos by default. It keeps files compact, but some older apps, websites, printers and Windows setups cannot open it. The right HEIC converter depends on where the converted images need to go and what details you need to keep. This guide shows you how to match a tool to the job.

Start with the intended use

Before you compare tools, write down what the converted files are for. A one-off upload to a form that rejects HEIC needs a different tool than an archive of several thousand family photos.

  • Destination: a website upload, email attachment, print shop, photo editor, document or long-term archive.
  • Volume: a few files now, or regular batches from a phone backup.
  • Environment: Windows, macOS, Linux, a phone or a browser on a shared or work computer.
  • Connection: whether you can send files to an online service, or must keep them offline.
  • What must survive: capture date, location, camera details, color accuracy, transparency or full resolution.

If you only need compatible files from a phone, you may not need a separate converter. iPhones can capture in a more compatible format instead of HEIC, and they can convert photos automatically when transferring them to a computer. Check your device settings first. This won't help with HEIC files you already have, but it can stop the problem for new photos.

Features that matter

Converters differ less in the basic task than in the details around it. Use the points below to read a feature list critically. A listed option tells you what a tool claims to support. It does not tell you how good the output looks, so test with your own photos.

Output formats

JPEG is the most widely accepted target and suits sharing and uploads. It is lossy, so pick a tool that lets you set the quality level. PNG is lossless and keeps transparency, but files are usually much larger than the original HEIC. Some tools also export WebP or AVIF, which are compact but not accepted everywhere. Choose the format your destination requires, not the one with the smallest file.

Metadata handling

HEIC photos often contain EXIF data such as capture date, camera model and GPS location. Some tools copy this data, some remove it, and some let you choose. For an archive, you usually want to keep dates. For public sharing, you may want to strip location. Also check whether the tool keeps the original capture date or only the file's modified date, because photo libraries sort by these differently.

Color and image content

Phone photos are often stored with a wide-gamut color profile. If a converter drops the embedded profile, colors can look duller or shifted in other apps. Look for an option to keep or convert the color profile, then compare a converted image with the original on the same screen. A HEIC file can also hold more than one image or extra data such as depth information. Many tools export only the main image. A Live Photo's motion part is a separate video file, so converting the still image will not include it.

Batch and workflow options

  • Converting whole folders, including subfolders.
  • Choosing an output folder so originals are not overwritten.
  • File naming rules and handling of duplicate names.
  • Resizing to a maximum width or file size for uploads.
  • Keeping or correcting image orientation.
  • Drag and drop, a right-click option, or a command-line mode for repeated jobs.

Privacy and file handling

Online converters upload your photos to someone else's server. Before using one, read its stated policy on how long files are kept, whether they are used for anything else and who can access them. Treat those statements as claims you cannot check yourself. For personal, medical, ID or work images, an offline tool on your own device avoids the upload entirely. With desktop software, check whether it needs an account, sends usage data or adds a watermark in a free version.

Check compatibility

Confirm that the tool runs where you work and can read your files before you rely on it.

  • Operating system: check supported versions, not just the platform name. Older systems may lack the HEIF and HEVC decoding the tool relies on.
  • Windows: some apps depend on Microsoft's HEIF and HEVC extensions from the Microsoft Store. The HEVC extension may not be free, so check whether your chosen tool needs it or includes its own decoder.
  • macOS: built-in apps such as Preview and Photos can open and export HEIC. Try them before installing anything.
  • Phones: some mobile apps convert on the device. Others send files to a server, so check which one you are using.
  • Input variants: make sure the tool accepts both .heic and .heif files, including photos from phones other than the iPhone.
  • Apps you already use: some photo editors and image viewers can open HEIC and save as JPEG, which may be all you need.

Build a shortlist

Turn your needs into a short list of requirements, then remove any converter that fails one of them. Do this before looking at extras.

  • Runs on my operating system and version without unsupported workarounds.
  • Exports the format my destination accepts, with quality control if it is JPEG.
  • Keeps, strips or lets me choose metadata, matching my privacy and archive needs.
  • Preserves capture dates where I need them.
  • Keeps or properly converts the color profile.
  • Handles my volume, including folder batches if needed.
  • Never overwrites originals by default.
  • Works offline if my files are sensitive, or has an upload policy I have read and accept.
  • Has no watermark, file-count limit or size cap that blocks my task, or I accept those terms.

Test each remaining tool on a small, varied sample: a normal photo, a portrait or depth photo, a burst or Live Photo, and one with location data. Compare the results with the originals for color, orientation, resolution, dates and location. Keep your original HEIC files until you have checked the converted copies. Converting back cannot restore detail or data that was lost.
