HEIC to JPG: the complete workflow on iPhone and Windows

Since the iPhone 7, Apple phones have saved photos in HEIC (High Efficiency Image Container) format by default. HEIC files are roughly half the size of equivalent JPEGs, which is kind to your storage — but plenty of upload forms, older Windows PCs, printers' kiosks and office software still refuse them. This guide covers every dependable route from HEIC to JPG: changing what the iPhone captures, converting on the phone, converting automatically during transfer, and converting on a Windows PC, plus the quality and privacy details that differ between them.

Option 1: Stop capturing HEIC (iPhone)

If a particular workflow always needs JPG — a work app, an older car head unit, a school portal — you can switch the camera itself:

1. Open Settings → Camera → Formats.
2. Choose Most Compatible instead of High Efficiency.

From now on the camera saves JPEG (and H.264 for video). The trade-off is real: JPEG photos take roughly twice the storage of HEIC at similar quality, and you lose some newer capture features in certain modes. This setting affects new photos only; it does not convert your existing library. Most people are better served by keeping High Efficiency and converting the few photos that need it — the options below.

Option 2: Convert during transfer (iPhone → computer)

The iPhone can convert on the way out, which is the least-effort route for a USB cable workflow:

1. Open Settings → Photos and scroll to Transfer to Mac or PC.
2. Choose Automatic (not "Keep Originals").
3. Copy the photos to the computer as usual; they arrive as JPG.

Note the limits of this trick: it applies to wired transfers to a computer. AirDrop to a Mac generally keeps HEIC unless the receiving app asks otherwise, and sharing sheets behave differently per app — the Files and Mail apps often convert, while some third-party apps pass the original file through untouched. If a form rejected your upload, do not assume the share sheet converted it; check the file name. A converted file ends in .jpg, an original in .heic.

Option 3: Convert on the iPhone itself

For a handful of photos, the built-in Files app works:

1. In Photos, select the pictures and use Save to Files to copy them into a Files folder.
2. In Files, long-press a photo (or select several), then choose Quick Actions → Convert Image where available, picking JPEG and a size.

Availability of that menu varies by iOS version. A Shortcuts workflow ("Convert Image" action) achieves the same thing on versions without it, and can process a whole album in one run. Converting on the phone is convenient, but check the output: some quick methods strip location metadata (good for sharing, bad for your own archive) and may downscale very large images. Keep the HEIC originals in your library as the master copies.

Option 4: Convert on Windows

Windows is where most HEIC frustration happens, and there are three levels to it:

1. Just viewing. The Windows Photos app can open HEIC once the HEIF Image Extensions are installed from the Microsoft Store (free; the companion HEVC Video Extensions is a separate, sometimes paid, item and is only needed for video). Viewing works, but many programs still cannot open the files.
2. Converting inside an app. With the extension installed, open the photo in Photos and use Save as / export to write a .jpg copy. Fine for one or two images; tedious for fifty.
3. Batch converting in the browser. For a folder of photos — say, a product shoot or a family album from someone else's iPhone — a local converter is faster and uploads nothing. The HEIC to JPG converter on this site decodes HEIC in your browser and exports JPG copies you can download individually or together; the files never leave your PC, which matters when the photos are someone else's.

Quality: what conversion does and does not lose

JPEG cannot hold everything HEIC can. Three differences are worth knowing. First, bit depth: HEIC can store 10-bit colour; JPEG is 8-bit. Converting can introduce slight banding in smooth gradients such as skies, though at high quality settings (90 or above) it is rarely visible in ordinary photos. Second, transparency and depth data: Portrait-mode depth maps and similar extras do not survive into a plain JPG — keep the HEIC if you may re-edit the portrait effect later. Third, Live Photos: a Live Photo is a still plus a short video; converting gives you the still frame only. None of this matters for a form upload or a print order, but it is why the HEIC original should stay in your archive even after you convert.

One pleasant surprise: converting does not normally rotate your photos wrongly. Orientation is carried in the EXIF data, and competent converters bake it into the pixels. If a converted photo appears sideways in an old program, that program is ignoring the orientation flag — re-exporting with a modern tool fixes it.

Metadata and privacy while you convert

Converted JPGs typically keep the capture date, camera model and — unless you remove them — GPS coordinates. Before you upload converted photos to a marketplace, forum or classifieds site, consider stripping location data with the metadata remover; the guide to EXIF and GPS metadata explains exactly what travels inside a photo. For your own archive copies, keep the metadata: future-you will want to know where a photo was taken.

Common problems

• "The file is damaged or unsupported" on a web form. The form accepts only JPG/PNG and the share sheet passed the HEIC through. Convert explicitly and check the .jpg extension before uploading.
• Photos open on one Windows PC but not another. The first has the HEIF extension installed, the second does not. Installing the extension fixes viewing; converting fixes everything else.
• Colours look washed out after conversion. Wide-gamut (Display P3) iPhone photos converted carelessly to sRGB can shift. Use a converter that performs colour management, and export at quality 90+.
• A .heic file that will not convert anywhere. It may actually be a HEIF sequence or a video in disguise (for example a Live Photo's .mov saved with the wrong name). Try opening it as video, or re-export the still from the Photos app.

Frequently asked questions

Is JPG quality worse than HEIC?

At the same file size, HEIC is more efficient. But a JPG exported at quality 90–95 from a HEIC original is visually indistinguishable in nearly all real uses — prints, web, forms and sharing. The conversion is not where quality problems come from; repeated re-saving at low quality is.

Can I convert HEIC to JPG without installing anything?

Yes — a browser-based converter such as the one on this site runs entirely on your device. No app install, and no upload to a conversion server.

Does converting remove the location from my photos?

Not reliably; many converters preserve EXIF data, including GPS. If privacy is the goal, remove metadata as a separate, deliberate step and verify the result.

Should I switch my iPhone to Most Compatible permanently?

Only if your everyday tools keep rejecting HEIC. You will roughly double photo storage use and give up some capture features. Converting the occasional photo is the cheaper habit for most people.

What about HEIC on Android or Mac?

Most modern Android phones open HEIC directly, and macOS has supported it natively since High Sierra — Preview and Photos can open HEIC and export JPG via File → Export. The pain point is mainly Windows and web forms.
