Commons:Project scope/Allowable file types
Currently the following formats are allowed:
- Images: SVG (for vector graphics), PNG (lossless format), JPEG (for photographs), GIF ("semi"-lossless format, but PNG is preferred), TIFF (lossless format, but PNG is preferred), XCF (allows layers and text).
- Video: WebM using VP8 codec (and Vorbis for the sound) or Ogg using Theora codec (usually with Vorbis for the sound). (new software uses the .ogv extension instead of .ogg for video, although .ogg is still usable) - Help:Converting video.
While SXW, SWC, SXD, and SXI (OpenOffice.org 1.x), as well as ODT, ODS, ODG, and ODP (OpenDocument) are theoretically permissible under the similar provisions to Commons:Scope#PDF_and_DjVu_formats these formats are currently disabled because we are currently unable to prevent people from hiding harmful or otherwise impermissible content inside OpenOffice's ZIP based container format.
