HEIC vs JPEG vs WebP vs AVIF — Image Format Comparison

July 13, 2026

Image formats have evolved dramatically. JPEG dominated for decades, but modern formats like HEIC, WebP, and AVIF offer significantly better compression and features. If you are a photographer deciding on a shooting format, a web developer optimizing page loads, or an iPhone user wondering why your photos are HEIC instead of JPEG, this image format comparison covers everything you need to know.

Each format targets different use cases. JPEG is the universal standard with unmatched compatibility. HEIC is Apple's modern format for iPhone photography. WebP is Google's web-optimized format. AVIF is the next-generation format with the best compression but the least support. Choosing the right format depends on your specific needs.

Which image format has the best compression? ▼AVIF offers the best compression, achieving files about 50% smaller than JPEG at equivalent quality. HEIC is close behind. WebP is about 30% better than JPEG.Is AVIF better than WebP? ▼AVIF provides 20-30% better compression than WebP and supports HDR and higher color depth. WebP has broader browser support and faster encoding. The best choice depends on your priorities.Does WhatsApp support HEIC? ▼No. WhatsApp converts HEIC images to JPEG when sent from iPhones. Convert HEIC to JPEG first to avoid quality loss from recompression.Which image format is best for web use? ▼WebP is the best choice for current web use with ~98% browser support. Use a JPEG fallback for maximum coverage. AVIF is excellent for future-proofing but requires a fallback.What is the difference between HEIC and JPEG? ▼HEIC uses HEVC compression to produce files about 50% smaller than JPEG, with support for 16-bit color, transparency, and live photos. JPEG offers universal compatibility but larger files and limited features.
