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.

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.

When Should You Use PNG vs HEIC?

Use PNG When...

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

Use HEIC When...

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

PNG vs HEIC: Key Differences

  • •The core technical difference: PNG relies on lossless compression whereas HEIC uses lossy compression.
  • •Moving from PNG (lossy) to HEIC (lossy) means the output file will be significantly smaller — but at the cost of some visual fidelity.
  • •How transparency is handled: HEIC does not support alpha channels — transparent areas in the source will become opaque.
  • •PNG files are typically 20KB to several MB while HEIC files range 50% smaller than equivalent JPEG
  • •Primary audience: PNG is built for graphics, logos, images requiring transparency scenarios, while HEIC focuses on ios photography, mobile devices — pick the format that matches your output requirement.

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.

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.
