About formats

HEIC (High Efficiency Image Container) is Apple's branded implementation of the HEIF (High Efficiency Image File Format) standard that uses HEVC (H.265) as its image compression codec. Apple adopted HEIC as the default photo format on iPhones and iPads starting with iOS 11 in September 2017, replacing JPEG for newly captured images. HEIC files store photographs compressed with the intra-frame coding mode of the HEVC video codec, which applies sophisticated prediction, transform, and entropy coding techniques that achieve roughly 50% better compression than JPEG at equivalent visual quality. The ISOBMFF (ISO Base Media File Format) container supports multiple images in a single file, enabling Live Photos (a still plus a short video clip), burst sequences, depth maps from dual-camera systems, and HDR gain maps that allow compatible displays to render extended dynamic range. HEIC also stores alpha channels, auxiliary images for computational photography features (portrait mode depth data, semantic segmentation masks), and comprehensive EXIF/XMP metadata. One advantage is storage efficiency: iPhones shooting HEIC use roughly half the storage of equivalent JPEG captures with no visible quality loss, a significant benefit on devices where storage is finite and photos accumulate rapidly. The format's integration with Apple's ecosystem is another key strength — HEIC files are natively supported across macOS, iOS, iPadOS, and iCloud Photos, and automatic JPEG transcoding during file sharing ensures compatibility when sending photos to non-Apple devices. HEIC can also be opened by Windows 10/11 (with codec), GIMP, ImageMagick, and Adobe Lightroom.

PICON (Personal Icon) is a small-format image type used in the X Window System ecosystem, developed by Steve Kinzler at Indiana University around 1990 as part of the picons (personal icons) database project. Picons are small, typically 48x48 pixel, color images used as visual identifiers for people, organizations, domains, and Usenet newsgroups in Unix mail readers, news readers, and other communication tools. The picon format is essentially an XPM (X PixMap) image stored with specific naming conventions and directory structures that allow software to look up the appropriate icon based on email address, domain name, or newsgroup name. The picons database organized thousands of these small images in a hierarchical directory structure keyed by domain name components (e.g., faces/com/example/user.xpm), enabling mail clients like exmstrstrstr and faces to automatically display a sender's photo or organizational logo alongside their messages. The system predated the modern concept of contact photos and avatars by more than a decade. One advantage is the system's pioneering role in visual identity for electronic communication: picons introduced the idea that email and Usenet messages should display a visual representation of the sender — a concept that eventually became standard in every modern email client, messaging app, and social media platform. The XPM-based format ensures that picons are displayable on any system with X Window libraries. Picon images are supported by ImageMagick, GIMP, and X Window display utilities, and the historical picons database remains archived online at Indiana University.

Frequently Asked Questions

Why convert HEIC to PICON?

PICON creates compact icon representations for X Window System desktops — useful for creating small preview icons from your iPhone photos.

What software uses PICON?

X Window System applications, ImageMagick, and Unix/Linux desktop environments that display personal icon thumbnails.

What size is a PICON?

PICON images are intentionally small — typically thumbnail-sized representations designed for icon display purposes.

Will my photo be reduced in size?

Yes — PICON is a compact format, so your HEIC photo will be scaled down to icon dimensions during conversion.

Is HEIC to PICON conversion free?

Yes, standard conversions are free. Premium plans handle batch processing for multiple icon generation.
