Lossless Animation

MNG stores sequences with PNG-quality lossless frames — perfect for creating high-fidelity animated previews of your T42 font glyphs.

PNG-Based Quality

Built on the PNG standard, MNG inherits full alpha transparency and lossless compression — converting T42 fonts yields crisp, artifact-free results.

Server-Side Generation

All rendering and encoding happens on our servers. No animation tools or font rasterizers required on your machine.

About formats

T42 (Type 42) is a PostScript font format developed by Adobe Systems that wraps a TrueType font inside a PostScript font dictionary, enabling PostScript printers equipped with a TrueType rasterizer to print TrueType fonts natively. The name reportedly references Douglas Adams' "The Hitchhiker's Guide to the Galaxy," where 42 is the answer to the ultimate question. Type 42 was introduced with PostScript interpreter version 2013 in the mid-1990s, with Adobe publishing the formal specification as Technical Note #5012 in July 1998. The format embeds the complete TrueType font data — outlines, hinting instructions, and tables — as a binary string within the PostScript sfnts dictionary entry, while wrapping it in standard PostScript font structure including CharStrings, Encoding, and FontInfo dictionaries. One advantage is preserved TrueType hinting: because the original quadratic spline outlines and grid-fitting instructions are passed directly to the TrueType rasterizer, the printed output matches the screen rendering quality that TrueType hinting was designed to deliver. This is superior to the alternative approach of converting TrueType outlines to Type 1 cubics, which discards hinting. Type 42 also enables PostScript workflows to incorporate the vast library of TrueType fonts bundled with Windows and macOS without manual font conversion. PDF generators commonly use Type 42 embedding when including TrueType fonts in PostScript-based output pipelines. The format bridges two major font technologies that evolved separately, ensuring interoperability across the PostScript and TrueType ecosystems.

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 T42 to MNG?

MNG extends PNG with animation support — it provides lossless frame sequences, making it suitable for animated font specimens or glyph showcases.

How do I open an MNG file?

GIMP, Konqueror, and some Firefox builds support MNG. ImageMagick and FFmpeg can also process and convert MNG files.

How does MNG compare to GIF?

MNG supports full-color lossless frames and alpha transparency, while GIF is limited to 256 colors. MNG is technically superior but less widely supported.

Can I convert many T42 fonts at once?

Yes. Convertio handles batch uploads — submit several T42 files and receive individual MNG outputs.

Is the conversion free?

Yes — completely free on Convertio, with no registration and no desktop software needed.
