What are Image Formats?
Image formats are standardized methods for organizing and storing digital images. Each format uses different compression algorithms, color depths, and features that affect file size, quality, and compatibility. Understanding these differences helps you choose the right format for your specific needs.
🆕AVIF (AV1 Image File Format)
Overview: AVIF is the newest image format, based on the AV1 video codec and HEIF container. It offers superior compression efficiency and supports modern features like HDR and wide color gamut.
Compression: Provides ~50% smaller files than JPEG with similar or better quality. Uses both lossy and lossless compression with up to 12-bit color depth.
Features: Supports HDR, wide color gamut, transparency, and animated sequences. 94% browser coverage as of 2025.
Pros: Best compression ratio, excellent quality, modern features, royalty-free
Cons: Slightly less browser support than WebP/JPEG, slower encoding
🌐WebP (Web Picture)
Overview: WebP is a modern format developed by Google, designed specifically for web use with excellent compression and feature support.
Compression: 30-50% smaller than PNG and significantly smaller than JPEG at similar quality levels. Supports both lossy and lossless compression.
Features: Transparency support, animation, 8-bit color depth. 97% browser coverage.
Pros: Excellent compression, universal support, fast encoding/decoding, transparency
Cons: Slightly larger files than AVIF, not ideal for print
🖼️PNG (Portable Network Graphics)
Overview: PNG is a lossless format designed as a replacement for GIF. It's ideal for graphics requiring perfect quality and transparency.
Compression: Lossless compression with no quality loss, but results in larger file sizes compared to lossy formats.
Features: Alpha channel transparency, 8-bit color (24-bit RGB), universal browser support, APNG for animation.
Pros: Lossless quality, transparency, universal support, excellent for graphics
Cons: Large file sizes, inefficient for photographs, no HDR support
📷JPEG (Joint Photographic Experts Group)
Overview: JPEG is the most widely used image format for photographs, with decades of adoption and universal support.
Compression: Lossy compression optimized for photographs. Small file sizes but quality degrades with repeated saves.
Features: 8-bit color depth, 97%+ browser coverage, fast processing, mature ecosystem.
Pros: Universal support, small file sizes for photos, fast, mature
Cons: Lossy compression, no transparency, limited to 8-bit color, no HDR
📄TIFF (Tagged Image File Format)
Overview: TIFF is a professional format used in print media, scanning, and archival applications where quality is paramount.
Compression: Supports both lossy and lossless compression, but typically used uncompressed for maximum quality.
Features: Multiple color spaces, rich metadata, layer support, lossless quality.
Pros: Lossless quality, professional standard, metadata rich, supports layers
Cons: Very large file sizes, not suitable for web, limited browser support
🍎HEIC (High Efficiency Image Coding)
Overview: HEIC is Apple's implementation of HEIF, used as the default photo format on iPhones, iPads, and Macs since iOS 11.
Compression: Uses HEVC (H.265) compression, providing 50% smaller files than JPEG with similar quality. Supports 16-bit color depth.
Features: Live Photos, depth data, HDR support, transparency, multiple images in one file.
Pros: Excellent compression, high quality, modern features, Apple ecosystem native
Cons: Limited web browser support, patent licensing concerns, limited compatibility outside Apple
