HEIC vs JPG: which should you actually use?
Most “HEIC vs JPG” articles crown a winner. That’s the wrong frame: one format is better at storing photos and the other is better at being accepted, and which matters more depends entirely on where your photos live. Here’s the comparison without the coronation.
The one-table version
| HEIC | JPG | |
|---|---|---|
| File size (same visual quality) | Smaller — commonly cited at ~40–50% less, varies by scene | Larger |
| Color depth | Up to 10-bit (smoother skies, less banding) | 8-bit |
| Transparency | Supported | Not supported |
| Multiple images per file | Yes (bursts, auxiliary data) | No |
| Opens on… | Apple devices, current Windows with codecs installed, Safari | Effectively everything since the 1990s |
| Browsers | Safari only | All |
| Upload forms, kiosks, old software | Frequently rejected | Universally accepted |
| Licensing | HEVC patent-encumbered | Patent-free for decades |
Read the table honestly and the shape of the answer appears: HEIC wins every technical row; JPG wins every compatibility row. The rest is deciding which rows describe your life.
Where the size claim comes from — and its limits
The famous “half the size” figure traces back to Apple’s 2017 introduction of the format, and independent comparisons since have generally landed in the 40–50%-smaller region for typical photos. But the ratio is scene-dependent: smooth gradients and skies compress brilliantly under HEVC; fine, noisy texture (foliage, fabric, low-light grain) narrows the gap. If you test your own photos, expect a range, not a constant. The honest summary is “HEIC is meaningfully smaller at matched quality, usually by a lot.”
Quality at matched size favors HEIC even more clearly: give both formats the same byte budget and the HEIC will show cleaner gradients and fewer block artifacts. That’s what a 25-years-newer codec buys.
The compatibility tax, itemized
What JPG’s universality actually saves you from, collected from the support-forum trenches:
- Windows machines that need a Microsoft Store codec (with a $0.99 component) before Photos will display a HEIC — details here.
- Chrome and Firefox showing a download prompt instead of the image, on every OS.
- Upload forms — job applications, government portals, listing sites — that reject the file outright, usually with an unhelpful error.
- Email recipients on older systems seeing an attachment they can’t open.
- Print kiosks and photo-book services that predate the format.
None of these are HEIC being a bad format. All of them are the world declining to license HEVC decoding. The distinction is philosophically interesting and practically irrelevant: the file still didn’t open.
Metadata: a tie, with an asterisk
Both formats carry full EXIF metadata — GPS location, timestamps, device model. Neither is more private than the other as shot. The asterisk: because HEIC files travel badly, they get converted a lot, and how you convert determines what leaks. Upload-based converters see your photos and their location data; a local converter sees nothing, and ours strips metadata from the output as a bonus. If privacy is a factor in your format choice, it’s really a factor in your conversion choice.
Recommendations by situation
All-Apple household, storage matters — stay on HEIC. You may literally never hit the compatibility wall, and you’ll fit years more photos on the same phone.
iPhone camera, Windows life — set the camera to JPEG (Settings → Camera → Formats → Most Compatible) and accept the storage cost. The daily friction of converting isn’t worth the megabytes for most people in this camp.
Photographer / archivist — keep HEIC originals (or better, shoot RAW where it matters); export JPG copies for anything that travels. Never let the traveling copy be your only copy regardless of format.
Occasional cross-platform sharing — keep shooting HEIC and convert the specific files that need it. The converter handles batches, so “that vacation folder for grandma’s PC” is one drag-and-drop.
Uploading to a picky form right now — convert to JPG at 90% quality; format-wise, JPG is accepted essentially everywhere a photo is expected. (Size and dimension limits are a separate question some forms add on top — the format conversion at least stops being the reason for rejection.)
What about WebP and AVIF?
They’re the same story with different politics. WebP (Google, 2010) and AVIF (from the Alliance for Open Media, royalty-free by design) are also better-than-JPEG formats, and both enjoy the full browser support HEIC never got — but desktop software and upload forms still lag on both. For web use, HEIC to WebP is a genuinely good conversion. For everything else, the gravitational pull of “opens everywhere” keeps ending at JPG, which is why our converter defaults to it.
Bottom line
There is no winner — there’s a storage format and an interchange format. HEIC is an excellent storage format hobbled by licensing; JPG is an ancient interchange format kept immortal by universality. Pick per role: HEIC (or RAW) at rest if the savings help you, JPG in motion, and a local, private converter as the bridge whenever a photo crosses from one role to the other.
