About formats

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.

MNG (Multiple-image Network Graphics) is an animation and multiple-image format designed as the animated counterpart to PNG, with its specification reaching version 1.0 on January 31, 2001. Developed by Glenn Randers-Pehrson and members of the PNG development community, MNG extends PNG's capabilities with support for frame-based animation sequences, slide shows, complex sprite overlays, and JNG (JPEG Network Graphics) frames for lossy compression of photographic content within the same container. An MNG file consists of a series of chunks (following PNG's chunk-based architecture): MHDR and MEND chunks bookend the datastream, with embedded PNG or JNG images as individual frames and control chunks (DEFI, FRAM, LOOP, ENDL, TERM, BACK, BASI, CLON, PAST, DISC, SHOW) directing playback timing, looping behavior, layer compositing, and memory management. The format supports both full-frame replacement and delta (difference) updates for efficient encoding of animations with static backgrounds, as well as object-based animation where sprites are defined once and repositioned across frames. One advantage is technical sophistication: MNG provides a level of animation control that GIF and APNG cannot match — frame-accurate timing, nested loops, conditional branches, interframe compression, and mixed lossy/lossless content within a single animation. The PNG-based foundation ensures lossless quality with full alpha transparency for each frame. MNG is supported by ImageMagick, GIMP, and various media players, though browser support was limited, which led to APNG's emergence as a simpler alternative for web animation.

Frequently Asked Questions

Why convert PICON to MNG?

PICON originated in Unix file managers and has narrow compatibility today. MNG offers animated image format related to PNG — a far more practical choice for sharing.

What apps support MNG?

You can view MNG with ImageMagick, XnView, Konqueror browser. These tools cover all major desktop and mobile platforms.

Is PICON to MNG conversion free?

Standard conversions are available for free on Convertio. Larger volumes or higher usage may benefit from a premium plan for additional capacity.

Does converting PICON to MNG affect quality?

Quality is maintained to the extent MNG supports. Since PICON is a small thumbnail/icon format from Unix systems, the visual data transfers cleanly to MNG.

How long does PICON to MNG conversion take?

Most PICON to MNG conversions complete within a few seconds. The lightweight nature of PICON images means fast processing times.

Can I convert multiple PICON files to MNG at once?

Yes — upload several PICON files in one session and Convertio processes them all into MNG simultaneously, saving you time.
