HEIC vs WEBP
A detailed comparison of HEIC Image and WebP Image — file size, quality, compatibility, and which format to choose for your workflow.
HEIC Image
Raster & Vector ImagesHEIC is the default photo format on Apple devices since iOS 11. It offers roughly 50% better compression than JPEG at similar quality but has limited support outside the Apple ecosystem.
About HEIC filesWebP Image
Raster & Vector ImagesWebP is a modern image format developed by Google that provides superior lossless and lossy compression. Files are typically 25-35% smaller than equivalent JPEG or PNG images at the same visual quality.
About WEBP filesStrengths Comparison
HEIC Strengths
- Roughly 50% smaller than JPEG at equivalent visual quality.
- 10- and 12-bit color depth supports HDR photography.
- Container format holds depth, Live Photo, bursts, and thumbnails in one file.
- Supports transparency and multi-image sequences.
- Built into iOS, macOS, and most modern Samsung and Google flagships.
WEBP Strengths
- Smaller file sizes than JPEG, PNG, and GIF at equivalent visual quality.
- Single format for lossy photos, lossless graphics, transparency, and animation.
- Full alpha channel support with smaller files than PNG.
- Now universally supported in all modern browsers.
- Open-source reference implementation (libwebp) by Google.
Limitations
HEIC Limitations
- Patent-encumbered (HEVC) — Windows users must buy a $0.99 codec pack from the Microsoft Store.
- Not supported by most web browsers or older image editors.
- Sharing to non-Apple platforms usually auto-converts to JPEG, losing metadata.
- Hardware decoding required for smooth performance; software decoding is CPU-heavy.
WEBP Limitations
- Some older software and image editors still don't read WebP natively.
- Max dimensions are 16,383 × 16,383 — lower than JPEG or PNG.
- Print workflows rarely support WebP (no CMYK, limited color management).
- Editing tools are less mature than JPEG/PNG; round-tripping can lose quality.

Frequently Asked Questions
HEIC (High Efficiency Image Container) is the default photo format on iPhones since iOS 11, based on the HEVC video codec. It offers roughly 50% smaller files than JPEG while maintaining superior image quality and supporting depth maps and Live Photos.
WebP is a modern image format developed by Google in 2010. It supports both lossy and lossless compression, transparency, and animation, while delivering files 25-35% smaller than JPEG and PNG equivalents.
HEIC files open natively on Apple devices, Windows 10/11 (with the HEIF extension from the Microsoft Store), and modern versions of GIMP and Photoshop. Google Photos also supports HEIC viewing and conversion.
WebP files open natively in Chrome, Firefox, Safari, Edge, and most modern image viewers. On Windows, the Photos app supports WebP. On macOS, Preview handles it from macOS Big Sur onward.
HEIC is superior in quality and file size but has limited support on non-Apple platforms. Use HEIC on Apple devices for storage efficiency. Convert to JPG when sharing with Windows users, uploading to websites, or printing.
AVIF offers even better compression than WebP (up to 50% smaller) but has less browser and software support. Use WebP for broad compatibility today. Choose AVIF for cutting-edge web performance if your audience uses modern browsers.
