HEIC vs JPG: Which Photo Format Should You Use?
HEIC saves storage; JPG opens everywhere. Here is what each format does well, how their quality and file size compare, and a simple rule for when to keep HEIC or convert to JPG.
If you own an iPhone, your photos are probably saving as HEIC without you ever choosing it - and most people only notice when a file refuses to open somewhere. So which is better, HEIC or JPG? The honest answer is that each wins in a different situation. Here is how to decide.
What HEIC is and why Apple uses it
HEIC (High Efficiency Image Container) is the file wrapper Apple has used for iPhone photos since iOS 11. It stores images encoded with HEIF, a modern format that squeezes a picture into roughly half the space of an equivalent JPEG while keeping the same visual quality. For a phone that doubles as everyone's main camera, that is a meaningful saving - more photos in the same storage, faster iCloud syncs, smaller backups.
HEIC also does things the decades-old JPEG simply cannot. It supports 16-bit color for smoother gradients, stores transparency and image sequences, and can hold the depth maps and edits behind features like Portrait mode and Live Photos in a single file. It is genuinely a better container - on Apple's terms.
Where HEIC breaks
The catch is compatibility. JPG (or JPEG) is the most universally supported image format in existence; essentially everything made in the last thirty years can open it. HEIC is newer and support is patchier, which is where the friction shows up:
- Windows PCs - older versions need an extra codec installed before HEIC files will even preview.
- The web - many sites, forums, and upload forms reject HEIC outright or fail to display it.
- Older apps and devices - non-Apple phones, legacy photo editors, and some email clients still choke on it.
If you have ever sent a photo and gotten "I can't open this" back, HEIC is almost always the reason. JPG never has that problem - which is its whole appeal.
Quality and file size compared
At the same visual quality, HEIC files are about half the size of JPEG, thanks to more efficient compression. Put another way, at the same file size HEIC generally looks better, holding up especially well in tricky areas like skies and shadows where JPEG tends to show banding.
Both are lossy formats, so every time you re-save you discard a little detail. The key thing to understand about converting is that HEIC to JPG is a one-way trade: you gain universal compatibility but give back the storage efficiency, and the JPG is re-compressed from the original. The result still looks great for everyday use, but if you care about archiving the best possible version, keep the HEIC original too.

When to keep HEIC vs convert to JPG
There is no need to pick one format forever. Match the format to what you are doing with the photo:
- Keep HEIC when the photos stay inside Apple's world - your library, iCloud, AirDrop to another iPhone or Mac - and you want to save space without losing quality.
- Convert to JPG when a photo is leaving your phone: emailing it, uploading to a website, sending to a Windows or Android user, or printing through a service that wants JPEG.
A good habit is to shoot in HEIC for the storage savings and convert copies to JPG only when you need to share. That keeps your library efficient while making sure nothing you send ever bounces. And if you are posting publicly, strip the location data on the way out - here is how to remove GPS and metadata from iPhone photos before they go anywhere.
When you do need JPGs, HEIC Snap makes the switch painless: batch-convert up to 100 photos to JPG, PNG, WebP, or PDF entirely on your device, with a quality slider and your originals left untouched. Keep the efficient format for yourself, hand out the compatible one - best of both.
