List of open source command line (batch oriented) file converter. It inspired by online-convert.com which this page try to provide the offline solution instead.
Notes (READ THIS FIRST):
- All apps below that marked with *(fc) may additionally (require fontconfig downloads as follow
fc-cache.exe 0.4 MB (not strictly needed but more convenient as one-time initializer)
fc-cache.7z 9 KB (Config files, some apps may already have it, some may not. just extract to the same place of executable)
- You can portably install missing/custom fonts in various format supported by Freetype into "fonts" subdirectory.
Vec2Web
Part of QCAD 2.x, is a GPL licensed app that render DXF (de facto CAD interchange format) into raster file (PNG) or vector file (EPS/Postscript) or SWF using QCAD as backend.

DWG2DXF
Part of libdxfrw which is part of LibreCAD project (a QCAD fork from which DWG feature only available commercially). It will read DWG files and able to convert to DXF, it's probably the only open source DWG reader that actually works (already better than libdwg). DWG2DXF also works very well with Vec2Web as long as you choose lower version DXF as output.

Ghostscript (fc)
A well known professional grade Postscript interpreter and PDF writer. It also read PDF but poppler (xpdf) may be more appropriate in some cases. It support lots of output format with excellent printout quality and able to redirect to Windows printer spooler. This build here is compiled with MinGW but has more features than the official, such SVG output support (via cairo) and DJVU distiller. However since this is file conversion oriented, most of specific printer devices were omitted. This build also support fontconfig similar to Miktex's Ghostscript, just store your custom fonts in subdirectory "fonts" and you're ready to go. FYI since Adobe Illustrator (*.ai) basically either based on Postscript or PDF, Ghostscript thus can convert them, e.g into SVG.
Supported devices :

FFMPEG (fc)
Despite might be unpopular among end users, FFMPEG is the most commonly used backend for video/audio transcoding because most popular apps requiring video capability use it! (VLC, Blender, Mplayer/Mencoder and many more). While there are many available builds out there, this build here is probably the only feature complete build for windows. This one also include hundreds third-party A/V FX libraries (frei0r and ladspa). In nutshell FFMPEG convert from every A/V format to every A/V format that users ever imagined be it lossy, lossless, industry-standard even legacy and obscure ones are supported.

ImageMagick (fc)
Widely popular in linux and quite commonly used as image editing backend by webservers, ImageMagick is mature image converter and editor. While many newer and leaner alternative/fork exists (e.g. OIIO, GraphicsMagick), none beat the completeness and its robust documentation. In Windows world XnView/ACDSee maybe more popular GUI-based converter however you can bet in term of features they are lacking. The build offered here is more feature complete and faster than the official (yes, it is!). There are separate 32bit and 64bit binaries available due to memory usage issue. IM support pretty much all kind of raster format you've ever heard plus few vector format as input. This build is AIO executable (patched to behave like GraphicsMagick) and build with the efficient MozJPEG.

GDAL
Fundamental backend for Open Source GIS apps. Provided here as an AIO executable, it support conversion of many raster/vector format with many editing capability too.

Poppler (fc)
Cross platform PDF renderer fork of UNIX-only x-pdf. Poppler interpret better than Ghostscript in some cases especially newer PDF version. It could become SVG-PDF round-trip for RSVG as it also use Cairo (pdftocairo), also round-trip for HTMLDoc (pdftohtml). This version is built with experimental CMYK enabled and in AIO executable mode.
