HEIC vs JPEG vs WebP vs AVIF — Image Format Comparison
July 13, 2026
Image formats have come a long way. JPEG was king for decades, but newer formats like HEIC, WebP, and AVIF give you way better compression and features. Whether you're a photographer choosing a shooting format, a developer trying to speed up your site, or an iPhone user wondering why your photos are HEIC instead of JPEG, this image format comparison has you covered.
Each format targets a different use case. JPEG is the universal standard — everything supports it. HEIC is Apple's modern format for iPhone photos. WebP is Google's web-focused format. AVIF is the newest kid on the block with the best compression but the least support. Which one you pick depends on what you're trying to do.
Frequently Asked Questions
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.
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.
No. WhatsApp converts HEIC images to JPEG when sent from iPhones. Convert HEIC to JPEG first to avoid quality loss from recompression.
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.
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.
