HEIC vs JPG: Why iPhones Use HEIC and When to Switch Back

HEIC vs JPG: Apple's modern HEIF/HEIC format, half the file size, but compatibility headaches. How to convert when you need to share with Windows or older software.

Quick verdict

HEIC saves storage on your iPhone with zero visible quality loss. JPG is what you convert to when sharing outside Apple — Windows, web, social media, email attachments.

Since iOS 11 (2017), iPhones save photos as HEIC (a flavor of the HEIF standard) instead of JPG. HEIC files are roughly half the size of equivalent JPGs at the same quality, with no visible difference. They also support transparency, 16-bit color, and multi-frame "Live Photos" — none of which JPG can do.

The problem: outside Apple's ecosystem, HEIC has poor support. Windows 10/11 needs an extension to view it. Most web browsers cannot display it. Older photo viewers and some printers reject it entirely.

Feature HEIC JPG
Typical file size ~50% of JPG Baseline
Quality at same size Better Worse
Transparency Yes No
Color depth 10-bit / 16-bit 8-bit
iPhone / Mac Native Native
Windows Requires HEIF extension Native
Web browsers No (must convert) Yes
Email forwarding Often fails for non-Apple recipients Universal

Keep HEIC when

  • You're only viewing photos on iPhone, iPad, or Mac.
  • You want to save storage (50% less per photo at no visible quality loss).
  • You shoot in 10-bit color or HDR and care about the extra dynamic range.

Convert to JPG when

  • You're sending the photo to a Windows or Android user.
  • You're uploading to a website, an old CMS, or a print service.
  • You're emailing the photo to anyone outside the Apple ecosystem.
  • You want maximum compatibility for the long term.

FAQ

Can ConvertFilesNow convert HEIC files?
Not yet, unfortunately — browsers do not include a HEIC decoder, so we cannot process HEIC files entirely in-browser without uploading them to a server (which we deliberately don't do). The simplest fix is to change your iPhone's camera format: Settings → Camera → Formats → "Most Compatible". This switches the camera to JPG.
How do I change my iPhone to save photos as JPG instead of HEIC?
Open Settings → Camera → Formats → tap "Most Compatible". From this point on, new photos are saved as JPG. Existing HEIC photos in your library are not converted — they stay HEIC.
Will switching to "Most Compatible" reduce photo quality?
You won't see a visible difference in the photos themselves, but the JPG files will be roughly twice the size of the equivalent HEIC. You also lose 10-bit color and Live Photo HDR.
Why does my Windows PC refuse to open .heic files?
Windows 10 and 11 can open HEIC after you install the free "HEIF Image Extensions" from the Microsoft Store. Without it, double-clicking does nothing. Alternatively, share the photo from iPhone using "Save to Files" with the format set to JPG.
Is HEIC really better than JPG?
Technically yes — same visual quality at half the file size, with extra features. But in 2026 HEIC is still a walled garden. JPG remains the universal format. For sharing: convert. For personal iPhone storage: HEIC is fine.
