HEIC vs JPG

HEIC stores photos at smaller sizes with more modern features, while JPG works almost everywhere with no conversion needed.

HEIC (a HEIF container using HEVC compression) is the default photo format on iPhones since iOS 11 and is designed to store the same image quality in roughly half the space of JPG. JPG (JPEG) is the long-standing universal photo format that every browser, operating system, and image editor can open. The practical trade-off is space and features versus compatibility: HEIC saves storage and supports newer capabilities, but JPG is the safe choice for sharing, uploading, and printing anywhere.

HEICJPG
CompressionHEVC-based, lossy (lossless is defined but rarely used); higher efficiencyDCT-based, lossy only; mature but less efficient
Typical file sizeOften around half the size of an equivalent-quality JPGLarger for the same visual quality
Color depth / HDRSupports 10-bit color and wide gamut; can carry HDR gain maps8-bit per channel, standard dynamic range only
Transparency & animationSupports alpha transparency and image sequences (e.g. Live Photo stills, bursts)No transparency, no animation; single still image
Browser supportLimited: Safari supports it; Chrome, Firefox, and Edge generally do not decode HEICUniversal across all browsers
Software & OS supportNative on Apple; Windows needs an extension; many older or non-Apple tools cannot open itOpens in virtually every OS, editor, and device without setup

Choose HEIC when

  • You want to save device or backup storage while keeping comparable image quality
  • You stay within the Apple ecosystem, where HEIC opens and edits natively
  • You need 10-bit color, wide gamut, or HDR detail preserved from the camera
  • You want a single file to hold transparency or an image sequence

Choose JPG when

  • You're uploading to a website, form, or app that may reject HEIC
  • You're sharing with people on Windows, Android, or older software
  • You're printing, or sending to a service that requires a standard format
  • You want a file that opens anywhere with no plugins or conversion

Keep HEIC if you live in Apple's ecosystem and want smaller files with modern color and HDR support. Convert to JPG whenever you need to share, upload, print, or open the image outside Apple devices, since JPG is accepted virtually everywhere. A common workflow is to store originals as HEIC and export JPG copies on demand.

Frequently asked questions

Why won't my HEIC files open on Windows or Android?
HEIC support outside Apple is patchy. Windows can open HEIC after installing the HEIF/HEVC extensions, and some Android versions and apps support it, but many tools and browsers (Chrome, Firefox, Edge) do not decode HEIC at all. Converting to JPG makes the image open everywhere without extra software.
Is converting HEIC to JPG lossy?
Yes. Both formats are lossy, so re-encoding a HEIC image as JPG applies a second round of compression. The quality drop is usually minor at high JPG quality settings, but it is not perfectly reversible. Keep your HEIC originals if you may need to re-export later.
Does converting HEIC to JPG lose HDR or wide-gamut color?
It can. JPG is limited to 8-bit, standard dynamic range, so 10-bit color, wide gamut, and HDR gain maps stored in a HEIC are flattened to standard color during conversion. The result still looks good on most screens, but the extra dynamic range is not carried over.
Will a HEIC photo really be smaller than the same JPG?
Usually yes. HEIC uses HEVC compression, which is more efficient than JPEG's older method, so a HEIC is often around half the size of a JPG at comparable quality. Exact savings depend on the image content and the quality settings used.
