How to Convert HEIC to JPG While Keeping Your Originals

Guides & Tutorials / Photo compatibility

To convert HEIC to JPG, open the photo in an app that supports HEIC and export a new JPEG copy. On a Mac, use Preview’s File → Export command. On an iPhone with Preview, use its Export menu. On Windows, a HEIC-capable editor such as GIMP provides an offline route. Keep the original until the exported file opens correctly and works in the destination.

Changing a filename from .heic to .jpg does not convert the picture. You need an export operation that writes JPEG image data. The useful goal is a compatible delivery copy, not replacing your whole photo library.

Convert for the destination, then keep the original

HEIC is associated with HEIF, the High Efficiency Image File Format. Apple’s HEIF and HEVC guidance explains why these formats are used: efficient storage with good visual quality. A HEIC photo is not necessarily broken because an upload form rejects it.

First read the receiving service’s requirements. It may specify JPG, a maximum file size, minimum pixel dimensions, or all three. A conversion solves the format requirement; it does not automatically solve every size or quality requirement.

Create two folders, such as Original HEIC and JPG for Upload. Use recognizable matching names so you can trace each delivery file back to its source. For important collections, retain an independent backup before reorganizing anything.

Convert HEIC to JPG with Preview on Mac

For a few images, Preview avoids installing another app. Apple documents this workflow in its image conversion guide:

1. Open the HEIC file in Preview.
2. Choose File → Export.
3. Choose JPEG from the Format menu.
4. Adjust the quality control if needed.
5. Choose a new filename or your separate output folder, then save.

For several files, open them in one Preview window and select the intended images in its sidebar before exporting. Check the selection and destination carefully. Begin with a small group so a mistaken setting does not produce hundreds of unsuitable copies.

If the images are inside Photos

Use the library’s export command rather than searching through its internal files. Select the images, choose File → Export → Export [number] Photos, select JPEG as the photo kind, and review size, quality, and color-profile options. Apple’s Photos export documentation covers these controls.

Choose the export that matches your purpose. An unmodified-original export preserves the source format, so it is not the route to request when you specifically need a JPG. If the library image has edits, decide whether the recipient needs that edited appearance or the original capture before exporting.

Export a JPEG copy on iPhone

On an iPhone with the Preview app available, open the image there. If it currently exists only in Photos, first save a copy to Files through the share sheet so it can be opened as a file. Apple’s Preview export instructions describe the conversion:

1. Open the image in Preview.
2. Tap the actions menu beside the filename, then Export.
3. Select JPEG and adjust its size/quality slider.
4. Confirm the export, choose a location, optionally rename the copy, and save.

If those controls are absent, check the user guide for your installed version or use the Mac or Windows route below. Do not assume that every older iPhone has the same app and menus.

Changing the camera setting affects future captures

On supported devices, Settings → Camera → Formats → Most Compatible selects JPEG for new photos. Apple documents this separately from exporting existing media. It does not retrospectively convert the HEIC files already in your library.

Use that setting only if it fits your ongoing workflow. If you normally benefit from efficient storage and need JPG only occasionally, exporting selected delivery copies may be more convenient than changing how every future photo is captured.

Convert on Windows with an offline editor

There are two separate capabilities: decoding the source image and exporting the target format. Installing a codec addresses the first. Microsoft’s HEIF guidance notes that Windows may need additional codecs to open downloaded files. It also says OneDrive for iOS stores HEIF originals; a successful OneDrive preview should not be mistaken for conversion.

For an offline editing route, obtain GIMP from its official download page. Its format-support reference lists HEIC import and JPEG export, while noting that HEIC support can depend on how a package is built.

1. Open one HEIC photo with File → Open.
2. Confirm the picture displays correctly before proceeding.
3. Choose File → Export As.
4. Choose the output folder and a filename ending in .jpg, or select JPEG in the file-type list.
5. Export, review the JPEG options, and complete the export.

GIMP’s Export File documentation explains the distinction: Save uses its native XCF project format, while Export produces formats for other applications. Renaming an XCF project to JPG would not solve an upload problem either.

If HEIC import fails, check that you are using a current official build and that the full source file downloaded successfully. Try another known-good HEIC to distinguish a file-specific issue from missing support. You can also export from the originating Apple device instead of troubleshooting an unfamiliar codec installation.

Choose quality and dimensions separately

JPEG quality controls compression; pixel dimensions describe the image’s width and height. Keep both in view. A large image with strong compression and a smaller image with gentle compression can have similar file sizes while looking quite different.

GIMP’s JPEG export reference explains that ordinary JPEG export is lossy and that repeated editing and exporting can discard more detail. It also cautions that quality numbers are not equivalent across applications. A value of 85 is not a promise to retain exactly 85% of an original.

Start from the original for each new delivery version. Inspect faces, small text, fine edges, and smooth gradients at a useful viewing size. If the result has obvious blocks or halos, increase quality or reconsider how much resizing the destination actually requires.

Do not promise a fixed percentage reduction. HEIC is already efficient, so a JPG copy can be larger. Also compare the visual result: some source capabilities may not survive the chosen output format or export settings. Keep the original for later editing and for any features the delivery copy does not preserve.

Review metadata before sending the copy

Changing the format is not a privacy-cleaning process. Apple’s location metadata guide explains that photographs can contain capture coordinates. Inspect the information attached to the exported file if the location of a home, customer site, or other private place should not be disclosed.

For sharing through iPhone Photos, Apple documents turning off Location in the share sheet’s Options. That is a control for that sharing workflow; do not assume it proves a separately exported file has no location information.

In an editor, review the export’s metadata options and inspect the saved copy. Consider what should remain, such as credit or copyright information, as well as what should be removed. Check the filename and the visible scene too: a street sign or document in the photograph can reveal information even without embedded coordinates.

For confidential photos, prefer an approved local workflow over uploading them to an unfamiliar conversion website. When sharing the finished copy, use suitable recipient permissions; our secure file-sharing guide covers that separate decision.

Verify the copy before deleting or delivering anything

• Open the output: confirm the actual exported file opens in another suitable viewer.
• Check the type: verify it is JPEG, not merely a renamed HEIC or an editor project.
• Check dimensions and size: compare both with the receiving service’s requirements.
• Inspect appearance: check orientation, crop, brightness, color, and fine details.
• Review privacy: inspect available metadata, the filename, and visible identifying details.
• Test delivery: upload one sample and inspect the receiving service’s result.

Once the sample works, convert the remaining group with the same reviewed settings. Inspect exceptions rather than assuming every photograph behaves identically. Retain the source collection and a clear distinction between archival originals and delivery copies.
