iPhones shoot HEIC by default. JPEG has been the universal photo format for thirty years. When you share a photo outside the Apple ecosystem, the format you use determines whether the recipient sees the image or a broken file icon. This article compares the two across every dimension that matters for sharing.
File size
HEIC wins decisively on file size. A typical iPhone photo in HEIC is 2–4 MB. The same photo saved as JPEG at equivalent visual quality is 4–8 MB. Over thousands of photos the difference is meaningful: HEIC roughly doubles how many photos you can fit in a given storage budget.
The size advantage comes from HEVC compression, which is significantly more efficient than JPEG's older DCT-based algorithm. HEVC can represent the same visual information in fewer bits by analyzing larger regions of the image at once instead of fixed 8×8 blocks.
Image quality
At the same file size, HEIC produces noticeably better quality than JPEG. Smooth gradients like sky and skin tones show less banding. Fine detail in hair, fabric, and foliage is better preserved. Compression artifacts — the blocky patches that appear in low-quality JPEGs — are less visible at equivalent sizes.
At high quality settings, both formats look excellent for casual viewing. The difference becomes apparent when you zoom in to 100% or print large. For everyday sharing on a phone screen, the quality gap is not the deciding factor — compatibility is.
Browser and platform compatibility
JPEG is universally supported. Every browser, operating system, email client, messaging app, social platform, image editor, and upload form has accepted JPEG for decades without any exceptions worth noting.
HEIC is not. As of 2026, only Safari on Apple platforms decodes HEIC natively. Chrome, Firefox, and Edge require OS-level codecs that most Windows and Linux users do not have. Android apps, most web upload forms, Windows email clients, and many image editors will either reject the file or display nothing.
For sharing to a mixed audience — a friend on Android, a colleague on Windows, a web form for an application — HEIC is the wrong format.
Inside the Apple ecosystem
If everyone in the exchange uses an Apple device running a recent OS, HEIC works transparently. AirDrop between iPhones, iMacs, and iPads handles HEIC without conversion. Photos app on macOS and iOS previews and edits HEIC natively. iCloud syncs HEIC files without modification.
Apple also added automatic conversion: when you share a photo outside the Apple ecosystem via the share sheet, the system re-encodes it as JPEG on the fly. This works for standard share actions but not for direct file transfers through iCloud Drive, third-party apps, or web upload forms.
EXIF metadata and privacy
Both formats carry the same EXIF metadata fields: GPS coordinates, capture time, camera model, lens data, and software version. Neither format is safer or more private than the other by default. Before sharing either format publicly, verify what metadata the file contains and strip fields you do not want to share, particularly GPS location.
When to stay with HEIC
- Personal storage on Apple devices where you never share externally
- AirDrop transfers exclusively within the Apple ecosystem
- iCloud libraries viewed only through Photos app
- Archiving photos where storage efficiency matters and compatibility does not
When to convert to JPEG
- Sharing with anyone on Android, Windows, or Linux
- Uploading to websites, forms, CMS platforms, or e-commerce systems
- Sending email attachments to a mixed audience
- Submitting photos for official applications, job postings, or government forms
- Publishing to social media via the web or third-party tools
- Any situation where you are unsure what device or app will open the file
How to convert before sharing
PhotoTools converts HEIC to JPG directly in your browser without uploading files to a server. Drop in the HEIC files, select JPG as the output format, and download the converted copies. The originals in your Photos library are not affected.
If you want to strip GPS and other metadata from the converted files before sharing, run them through the EXIF remover after conversion. The two tools together give you a compatible, privacy-clean file ready for any recipient.
Frequently asked questions
Should I use HEIC or JPG?
Use HEIC for personal storage on Apple devices, where it saves roughly half the space. Use JPG whenever you share outside the Apple ecosystem, upload to websites or forms, or send to Android and Windows users — JPG is universally compatible.
Is HEIC better quality than JPG?
At the same file size, yes — HEIC shows less banding in gradients and preserves fine detail better thanks to HEVC compression. At high quality settings both look excellent for casual viewing, so for sharing the deciding factor is compatibility, not quality.
Why won't my iPhone photo open on Android or Windows?
Because it's a HEIC file, which most non-Apple browsers and apps can't decode. Convert it to JPG before sharing and it will open on any device.
Does converting HEIC to JPG remove location data?
Not always — some converters carry EXIF (including GPS) into the JPG. If privacy matters, run the converted file through an EXIF remover and verify before sharing.
