Social media image and video size limits
What each platform accepts as an upload: how large a file may be, how long a video may run, how many files fit on one post and which formats go through. One table per platform, generated from our connector code.
這是平台限制，而非正在運作的排程功能
Why there are no pixel dimensions here
This dataset records what an upload is rejected for: file size, duration, attachment count and format. It does not record recommended pixel dimensions, so this page prints none. A recommended crop we had not verified would be a guess, and a guess is what sends a person back to redo the artwork.
Why a platform can be missing
A platform with no connector in this build has no recorded media limits, so it has no table here. An empty table of zeros would read as a set of real ceilings, which is the one thing it must not do.
Check a real file against these
The preflight checker takes a file size, a duration and a draft, and tells you which platforms would reject them. It runs in your browser as well.
這些數字從何而來
每項限制都是從此程式碼庫中的連接器功能程式碼產生，每一列平台都附有其來源的官方文件頁面，以及有人閱讀該頁面的日期。
這些工具不會發布任何內容。目前尚無任何連接器完成供應商驗證，因此此處尚無任何工具能連線帳號。
