HEIC (High Efficiency Image Container)
Apple's standard for high-quality, space-saving mobile photography.
HEIC (High Efficiency Image Container) is the default image format for iPhones and iPads. Introduced by Apple in 2017 (iOS 11), it is based on the HEVC (H.265) video compression standard. HEIC was designed to solve a specific problem: smartphone cameras were capturing more detail than ever, filling up storage space rapidly. HEIC files are roughly half the size of JPEGs with equivalent quality, effectively doubling the number of photos a user can store on their device. While technically superior to JPEG, HEIC is hindered by patent licensing issues, which has prevented it from being supported natively in web browsers like Chrome and Firefox. It remains primarily a storage and capture format rather than a web delivery format.
HEIC is a container format (based on ISO Base Media File Format) that wraps HEVC-encoded image data. Because it is a container, a single .heic file can hold multiple images (like a burst shot or a Live Photo), audio, and depth map data for portrait mode effects. It supports up to 16-bit color, enabling it to capture the wide color gamut (P3) used by Apple's displays and cameras. This is a significant upgrade over JPEG's 8-bit sRGB limitation.
The HEIF standard was finalized by MPEG in 2015. Apple adopted it in 2017, instantly making it one of the most common image formats in the world by volume of photos taken. Microsoft added support to Windows 10 via an extension, and Android added native support in version 10 (2019).
TIFF (Tagged Image File Format)
The venerable standard for print, scanning, and archival.
TIFF (Tagged Image File Format) is one of the oldest and most robust image formats still in use. Created in 1986 by Aldus (later acquired by Adobe), it was designed to be a universal standard for desktop publishing and scanning. TIFF is a container format, meaning it can hold almost any kind of image data—compressed or uncompressed, RGB or CMYK, 8-bit or 32-bit. This flexibility makes it the go-to choice for the printing industry, professional photographers, and archivists who need a format that preserves maximum quality and metadata without the compatibility headaches of proprietary RAW files.
A TIFF file is built around 'tags' that describe the image data. This allows it to support a vast array of features, including multiple pages (used for faxes and document scans), multiple layers (like a PSD file), and various color spaces like Lab and CMYK that are essential for printing. TIFF supports multiple compression schemes. The most common are LZW (lossless) and ZIP (lossless), but it can also hold JPEG (lossy) data. Uncompressed TIFFs are standard for archival because they are future-proof and require no decoding algorithm that might become obsolete.
TIFF was the first format to bring high-resolution, grayscale, and later color images to the desktop publishing revolution of the late 80s. While JPEG took over the web and consumer photography, TIFF remained the king of the pre-press and scanning world. It hasn't changed much since Revision 6.0 in 1992, which is a testament to its robust design.
