What is HEIC?

HEIC (High Efficiency Image Container) is a modern image format developed by the HEVC industry group. It uses advanced compression to achieve much smaller file sizes than JPEG.

What is PNG?

PNG (Portable Network Graphics) is a raster graphics file format that supports lossless data compression. PNG was created as an improved, non-patented replacement for GIF.

When Should You Use HEIC vs PNG?

Use HEIC When...

Reach for HEIC when your priority is ios photography, mobile devices — its efficient compression makes sharing fast and storage minimal.

Use PNG When...

Reach for PNG when your priority is graphics, logos, images requiring transparency — its uncompromising quality ensures every detail is preserved.

HEIC vs PNG: Key Differences

  • •The core technical difference: HEIC relies on lossy compression whereas PNG uses lossless compression.
  • •Moving from HEIC (lossless) to PNG (lossless) means the output file will be larger — but every bit of the original is preserved.
  • •How transparency is handled: PNG supports transparency, so alpha information is preserved during conversion.
  • •HEIC files are typically 50% smaller than equivalent JPEG while PNG files range 20KB to several MB
  • •HEIC is optimized for ios photography, mobile devices while PNG is designed for graphics, logos, images requiring transparency — choose based on your specific workflow needs

Advantages of HEIC

  • ✓HEIC compresses data using lossy methods, keeping file sizes manageable for iOS photography, mobile devices.
  • ✓Industry-wide support means HEIC files open anywhere — from legacy systems to the latest devices.
  • ✓Small file sizes make HEIC ideal for email, web uploads, and cloud storage.
  • ✓From Adobe Photoshop to open-source alternatives, HEIC works out of the box.

Advantages of PNG

  • ✓PNG uses lossless compression tailored for Graphics, logos, images requiring transparency.
  • ✓PNG is supported natively on virtually every device, browser, and operating system.
  • ✓PNG files are bit-for-bit perfect, preserving every pixel and sample for professional work.
  • ✓PNG integrates seamlessly with all major creative tools and workflows.

Troubleshooting HEIC to PNG Conversion

  • !Converting HEIC to PNG gives blurry output → increase the quality setting before conversion
  • !Colors look different in PNG than HEIC → check color profile mismatch (sRGB vs Adobe RGB)
  • !File size changed more than expected → PNG uses different compression, file size differences of 2-5x are normal
  • !Transparent areas in HEIC turned white in PNG → PNG may not support transparency

About HEIC and PNG

HEIC

HEIC is Apple's efficient photo container. While compact and high quality, its limited support outside the Apple ecosystem makes sharing difficult.

PNG

PNG gives you a lossless, universally supported image with transparency. Converting HEIC to PNG is ideal when you need pixel-perfect fidelity or a transparent background for design and web work.

Common Use Cases

  • Use an iPhone photo as a lossless asset in a design or web project.
  • Preserve maximum quality before editing a captured image.
  • Create a transparent graphic from a photo shot on an iPhone.
  • Archive HEIC photos in a fully compatible, open format.

FAQs

Is converting HEIC to PNG free?

Yes, GoConvertFile offers free conversion of HEIC to PNG for files up to 100MB.

Does HEIC to PNG preserve quality?

Yes, PNG uses lossless compression. However, HEIC files from iPhones use HEVC compression, so the PNG will be larger but maintain full visual quality.

Why convert HEIC to PNG?

PNG has universal compatibility across all platforms, browsers, and image editors. Use PNG when sharing photos with users on older systems that do not support HEIC.

How long does it take to convert HEIC to PNG?

Most HEIC to PNG conversions complete within seconds for standard-sized files. Larger files may take longer depending on the conversion complexity.

What is PNG best used for?

PNG is ideal for graphics, logos, images requiring transparency. Portable Network Graphics - lossless compression with transparency

Does converting HEIC to PNG lose quality?

No, converting HEIC to PNG does not cause additional quality loss — PNG uses lossless compression. However, any artifacts already present in the original HEIC file will persist in the PNG output.

What file size should I expect after converting HEIC to PNG?

PNG files are typically 2-5x larger than equivalent HEIC files because PNG preserves all pixel data. This is expected and necessary for lossless quality.

Will transparency be preserved when converting HEIC to PNG?

Yes, PNG supports transparency. Alpha channel information from HEIC is preserved during conversion.
