Attaching files

You can convey information by attaching a variety of file types to your issues and pull requests.

警告:如果在拉取请求、问题评论或 GitHub 支持门户 票证中附加了文件,则任何人都可以查看匿名 URL,无需身份验证,即使该拉取请求位于专用存储库中。 要对敏感媒体文件保密,请从需要身份验证的私有网络或服务器提供它们。 有关匿名 URL 的详细信息,请参阅“关于匿名 URL”。

To attach a file to an issue or pull request conversation, drag and drop it into the comment box. Alternatively, you can click the bar at the bottom of the comment box to browse, select, and add a file from your computer.

When you attach a file, it is uploaded immediately to GitHub and the text field is updated to show the anonymized URL for the file. For more information on anonymized URLs see "About anonymized URLs".

Tip: In many browsers, you can copy-and-paste images directly into the box.

The maximum file size is:

  • 10MB for images and gifs
  • 10MB for videos uploaded to a repository owned by a user or organization on a free GitHub plan
  • 100MB for videos uploaded to a repository owned by a user or organization on a paid GitHub plan
  • 25MB for all other files

We support these files:

  • PNG (.png)
  • GIF (.gif)
  • JPEG (.jpg)
  • SVG (.svg)
  • Log files (.log)
  • Microsoft Word (.docx), Powerpoint (.pptx), and Excel (.xlsx) documents
  • Text files (.txt)
  • PDFs (.pdf)
  • ZIP (.zip, .gz)
  • Video (.mp4, .mov)

Note: Video codec compatibility is browser specific, and it's possible that a video you upload to one browser is not viewable on another browser. At the moment we recommend using h.264 for greatest compatibility.
