How to Convert HEIC to JPG

HEIC is the default photo format on iPhones since iOS 11, and it’s still a compatibility headache nearly everywhere else. Windows users double-click a shared HEIC and get an error; older photo-printing kiosks reject it; many web publishing tools and CMSes choke on it. JPEG, by contrast, works everywhere, at the cost of larger files and no support for features like HDR or multi-image burst storage. Converting is usually one-click, but there are quality, metadata, and workflow choices worth making consciously. This guide explains why HEIC exists, when to convert, and how to keep EXIF through the conversion.

Why iPhones shoot HEIC

HEIC (High Efficiency Image Container) uses the HEVC codec to compress photos roughly 50% smaller than JPEG at the same visual quality. On a 256 GB iPhone that’s real money: your Photos library holds about twice as many pictures.

It also supports multi-image containers (Live Photos, burst sequences), wider color gamut, and 10-bit color for richer HDR. These are the reasons Apple switched to it by default. The downside: HEIC is patent-encumbered HEVC, which has kept it out of many third-party ecosystems.

Where HEIC breaks compatibility

HEIC works in Apple’s ecosystem and modern versions of most major platforms, but has gaps:

• Windows 10/11: needs an extension pack (sometimes paid) to preview.
• Older Android: partial support; depends on OEM.
• Many CMSes and forums: rejected as unsupported upload.
• Print kiosks and photo labs: often require JPEG.
• Legacy desktop apps: Microsoft Office, many PDF generators, older image editors.
• Email previews: recipients on older mail clients see nothing.

If the destination is outside the Apple/iCloud bubble, JPEG (or WebP/PNG) is safer.

The quality cost of conversion

Converting HEIC to JPEG means decoding the HEIC, then re-encoding as JPEG. JPEG is less efficient, so a quality-matched JPEG is roughly 2× the file size of the original HEIC. A quality-90 JPEG typically looks indistinguishable from the HEIC source on a phone screen; dropping to quality 75 saves substantial bytes with minor visible cost.

Don’t convert and then re-compress repeatedly. Each round trip bakes in more artifacts. Pick a quality setting once and stick with the converted file.

Keep EXIF through the conversion

HEIC files carry full EXIF — capture date, GPS, camera settings. A good converter copies all of it into the JPEG. A bad converter drops metadata, which can cause:

• Sideways photos (lost Orientation tag).
• Photos appearing in “no date” sections of photo libraries.
• Lost GPS data for map views.
• Lost authorship and copyright for professional files.

Check the output of any new converter against one of your files before trusting it for a batch.

Live Photos and multi-image HEICs

A Live Photo is a HEIC image paired with a short MOV video. Converting the HEIC gives you the still image; the motion is lost unless the tool extracts the MOV separately. Some converters output both a JPEG and an MP4; most just give you the still frame.

Burst HEICs (multiple frames in one container) typically convert to the first or “key” frame unless the tool lets you extract all frames.

Batch conversion

The most common batch scenario: you transferred a folder of iPhone photos to a Windows PC for editing. Every file is HEIC and nothing wants to open them. A good batch converter:

• Handles recursive folder trees.
• Lets you set one quality level for the whole run.
• Preserves EXIF.
• Bakes orientation before stripping the tag.
• Outputs to a separate folder to preserve the HEIC originals.

Alternative targets: WebP and PNG

JPEG is the default HEIC conversion target because of ubiquity, but it’s not the only option:

• WebP matches HEIC’s efficiency roughly and is supported in all modern browsers and many tools. Good for web upload.
• PNG is lossless — use when converting screenshots or images with text/UI elements for archival quality.
• AVIF matches or beats HEIC efficiency and is gaining support; still too new for some pipelines.

If the destination is a website you control, converting HEIC straight to WebP skips the JPEG step entirely.

iPhone: stop shooting HEIC if you prefer JPEG

If HEIC consistently causes friction in your workflow, change the capture setting on the iPhone itself:

Settings > Camera > Formats > Most Compatible

This switches capture to JPEG (and H.264 video) at the cost of storage. Existing HEICs don’t convert retroactively, but all new photos will be JPEG from that point forward.

AirDrop and share-sheet auto-conversion

iOS tries to be helpful: when you AirDrop a HEIC to a Mac, it stays HEIC; when you share to many third-party apps, iOS often converts on the fly to JPEG. This is why some HEICs reach a Windows PC as JPEGs already — not because the source was JPEG, but because the share path converted.

If you’re getting inconsistent formats from different transfer methods, this is why. For predictability, either set Capture to “Most Compatible” or always transfer the originals (iCloud Photos download or a cable copy of DCIM).

Preserve color space

iPhones shoot in Display P3, a wider color gamut than the standard sRGB. When converting to JPEG, the tool can either:

• Embed the P3 profile in the JPEG (modern browsers and apps respect it, colors look correct).
• Convert colors to sRGB (safer for dumb viewers; wide-gamut colors get compressed).

For web upload where reach matters more than saturation, sRGB is the pragmatic choice. For photo printing and archival, keep the P3 profile if the printer or destination supports it.

Browser-based versus desktop conversion

Three categories of tools:

• Browser-based (client-side): files never leave your device; runs WebAssembly locally. Best for privacy; limited by browser memory on huge batches.
• Online services with upload: fast and scalable, but your photos are on someone else’s server. Read the privacy policy.
• Desktop apps: best for huge libraries and repeat workflows; slower to set up.

For sensitive photos — medical records, family photos, document scans — client-side tools are the only safe option. For mundane snapshots, upload-based conversion is faster and usually fine.

Handling conversion errors

Some HEIC files fail to convert because they contain features unsupported by the converter: Live Photo video streams, depth maps for portrait mode, or vendor-specific HDR containers. When a conversion errors:

• Try a different tool — different libraries handle different edge cases.
• Open the HEIC in Photos (Mac) or the iPhone and re-export to JPEG from there.
• If the file is on iCloud Photos, set “Transfer to Mac or PC” to “Automatic” in iPhone settings — this auto-converts to JPEG during sync.

Disk space impact

Converting a library of HEICs to JPEGs roughly doubles storage use for the image collection. A 200 GB iCloud library becomes a 400 GB folder of JPEGs. Think about whether you need all of them as JPEG or only specific ones (the ones you’re sharing, editing, or printing).

A selective-conversion workflow — keep HEIC as the master library, convert on demand for specific uses — beats full-library conversion for most users. Apple’s own Photos app does exactly this when you share outside the ecosystem.

Naming conventions for mixed libraries

If you’re mid-transition (some HEIC, some JPEG) and want to keep both, a clear naming suffix avoids confusion:

IMG_1234.heic       (original iPhone file)
IMG_1234.jpg        (converted, same content)
IMG_1234-edited.jpg (post-conversion edits)

Some converters append _converted automatically. Pick one pattern and stick with it — mixed conventions in a library with 5000 photos is a permanent organization problem.

Common mistakes

Using a converter that drops EXIF silently, and discovering weeks later that your converted library has no dates or GPS. Converting a HEIC to JPEG at quality 60, saving over the original, and losing detail that never comes back. Ignoring the Orientation tag and publishing sideways photos. Trying to email someone a HEIC and wondering why they can’t open it — convert first. And the subtle one: converting HEIC to PNG thinking PNG is “higher quality” — technically lossless, yes, but you can’t un-compress what HEIC already threw away, and the resulting PNG is often 4–8× larger for no visible gain.

Run the numbers

Our HEIC to JPG converter handles single files and batches, preserves EXIF, bakes orientation safely, and offers quality presets. For other format conversions — PNG to WebP, JPEG to AVIF — the more general image format converter covers them all. And if the converted files are still bloated, the image compressor trims them without touching pixel dimensions.
