Why shouldn't I upload my writing as a PDF?

[edit]
  • PDF files are impractical, verging on impossible, for other users to edit. Wikis are supposed to be a collaborative effort, not just a single user dropping off a finished document.
  • The MediaWiki software treats PDF files like images, and only displays the first page in thumbnails and other previews. Reading the full document requires multiple clicks, and the reading experience is not integrated with the wiki.
  • Text in PDF files is not accessible to the wiki's search features, and sections of longer documents cannot be linked to. This makes it exceedingly difficult for readers to find relevant content in these files.

What should I do instead?

[edit]

That depends on what you're uploading:

An encyclopedia article I've written
Encyclopedia articles belong on your language's Wikipedia.
An essay or instructional piece I've written
That sounds like it might belong on Wikibooks or Wikiversity. Head over there and see if it'd be a fit.
My CV or autobiography
Please don't upload these. Wikimedia is not an appropriate place for these documents.
A picture
Please don't upload images as PDF. Photographic images should be uploaded as a JPEG file; vector graphics should be SVG.

Wait, why does Commons accept these files at all?

[edit]

Because, in some cases, there's no viable alternative.

Most legitimate PDF uploads fall into four basic categories:

  1. Official government publications which were released in PDF format.
  2. Published academic papers which have been released under an open license and are referenced from project wikis.
  3. Scans of out-of-copyright books used on Wikisource.
  4. Slides for presentations made within the Wikimedia organization, or at its events.
