Add images, video or a PDF to a post

Before you start

Pick your channels first. Each platform allows a different number of files, and the composer only lets you attach as many as the strictest selected platform accepts. See What each platform accepts.

Attach files

  1. In Create Post, under Media, click the add tile (Add or upload media).
  2. The Select Media window opens. The badge shows how many you picked out of the most you can attach, for example 2/4.
  3. Click files from your library to select them. Use Search media... to find one by name.
  4. To add a new file, click Upload and choose images, a video or a PDF. New files appear at the top and are selected for you.
  5. Close the window. Your files show under Media.

Set the order

Drag the files to reorder them. The order you see is the order they appear in the post, for example in a LinkedIn image post. Click a file to view it full size.

Rules to know

  • Images, video and PDFs don't mix. A post has either images, or one video, or one PDF. If you try to add a PDF next to images, you see Not on the same post.
  • Audio can live in your library, but it can't be attached to a post.
  • When you reach the most files allowed, extra clicks do nothing.
  • If you add a channel after picking media, the post may break that platform's rule, for example Only 4 images per post — 9 attached. Remove files or remove the channel.

If an upload fails

You see … file(s) failed with the reason. The usual causes:

  • the file is too large for this upload path — see the table above
  • the format is not supported — use JPG, PNG, GIF, WebP, MP4, MOV, WebM, M4V or PDF

Uploaded files stay in your Media library for next time.
