About formats

EMF (Enhanced Metafile) is a vector graphics format developed by Microsoft as the successor to WMF (Windows Metafile), introduced with Windows NT 3.1 in July 1993. EMF records a sequence of GDI (Graphics Device Interface) function calls that describe vector shapes, text, embedded bitmaps, and rendering attributes in a device-independent manner. Unlike WMF's 16-bit coordinate system limited to 65,536 units, EMF uses 32-bit coordinates and adds support for Bezier curves, advanced path operations, world coordinate transforms, gradient fills, and extended text capabilities including Unicode. The format functions as a graphics recording mechanism — applications capture their drawing operations into an EMF file, which can then be replayed at any scale on any device with full geometric precision. One advantage is native Windows integration: EMF is the standard clipboard and spooler format for vector content across the Windows ecosystem, enabling lossless copy-paste of graphics between Office documents, design tools, and presentation software without rasterization. Resolution independence is another key strength — EMF graphics scale smoothly from screen display to high-resolution print output. An extended variant, EMF+, introduced with GDI+ adds anti-aliasing, alpha transparency, and advanced brush types. EMF remains deeply embedded in Windows-based publishing, technical documentation, and enterprise document workflows.
Developer: Microsoft
Initial release: July 27, 1993
SIX is a file extension for SIXEL (Six Pixel) graphics data, a bitmap graphics format developed by Digital Equipment Corporation (DEC) in 1983 and introduced with the LA50 dot matrix printer. SIXEL encodes images as a sequence of printable ASCII characters, where each character represents a column of six vertical pixels (a 'sixel') — the character's ASCII value minus 63 provides a 6-bit binary pattern, with each bit controlling one pixel in the vertical column. The encoding is structured as a series of sixel bands (each six pixels tall) across the image width, with control sequences for color selection (up to 256 registers with HLS or RGB specification), repeat counts (run-length encoding for efficiency), carriage return, and newline commands. SIXEL data is transmitted to the output device using DEC's standard escape sequence protocol, embedded within the text stream alongside regular character output. Originally designed for DEC's line of printers and later supported by DEC VT-series terminals (VT240, VT330, VT340), SIXEL has experienced a remarkable revival in modern terminal emulator software. One advantage is terminal-native image display: SIXEL allows images to be rendered directly within a text terminal session without requiring a graphical window system, enabling command-line tools to display graphs, photographs, and previews inline with text output. This capability has driven adoption in modern terminals like mlterm, xterm, WezTerm, and foot. SIX/SIXEL data can be generated by ImageMagick, libsixel, and chafa, and viewed in any SIXEL-capable terminal emulator.

Why convert EMF to SIX?

Windows Enhanced Metafiles lack broad compatibility. Converting to SIX lets you use the graphic on the web, on mobile, or in any editor.

Which applications support SIX?

You can open SIX files with DEC terminal emulators, xterm with Sixel support, or mlterm.

Is EMF to SIX conversion free on Convertio?

Yes — convertio.tools lets you convert EMF to SIX at no cost. Premium plans offer expanded capacity for larger workloads.

Is a Convertio account needed for EMF to SIX?

No — you can convert EMF to SIX without creating an account or providing any personal information.

Can I convert EMF to SIX on a Mac or Linux machine?

Yes — Convertio is browser-based and works equally well on Mac, Linux, Windows, Chromebooks, and mobile devices.

Is EMF to SIX conversion fast?

Very fast — Convertio processes files on cloud servers, so even older or mobile devices get quick results.
