​
Adding media

There are several ways to add media to your post:
  • Drag and drop - Drop files directly into the editor
  • Click the media button - Click the (+) button to browse your computer
  • Paste from clipboard - Cmd/Ctrl + V for screenshots or copied images

​
Editing images

Click on the paintbrush icon next uploaded image to open the built-in image editor. You can make adjustments before publishing without leaving Ordinal.
Select from preset aspect ratios or enter a custom ratio.Presets include:
  • Square (1:1) - Instagram, LinkedIn, Facebook
  • Portrait (4:5) - Instagram Feed, Facebook
  • Landscape (16:9) - Twitter, YouTube
  • Vertical (9:16) - Reels, Stories, TikTok, YouTube Shorts
You can also type a custom aspect ratio (e.g., “3:2”) for specific needs.
Ordinal automatically compresses oversized files to meet platform limits.

​
Reordering assets

For posts with multiple images or videos, hover over the assets and click the Reorder button. From there, drag and drop assets to reorder them. The order you set is the order they’ll appear in the published post. On platforms that support carousels (Instagram, LinkedIn, Twitter, Facebook, Threads), the first image becomes the cover that users see before swiping.

Cover photos for videos

For Instagram Reels, Facebook video and Reels, and LinkedIn video posts, you can set a custom cover photo that previews your video on each platform. Open a video post and select Cover Photo to launch the cover photo modal. Use the source dropdown at the top of the modal to choose how to set the cover:
Pick any frame from the video you uploaded - no external image required.
  1. In the cover photo modal, choose Select cover photo from uploaded video.
  2. Scrub the filmstrip or use the left and right arrow keys to move the playhead. The preview and timestamp update as you scrub.
  3. Select Save Cover Photo to set the chosen frame as your cover.
Your selection is saved with millisecond precision, so reopening the modal restores the exact frame you picked.
To clear a custom cover and fall back to the platform default (the first frame of the video), switch to Select cover photo from uploaded video, select Reset to Default (0:00), and then Save Cover Photo. Saving at 0:00 deletes any existing cover photo.

Troubleshooting

  • Check file size - Images under 10MB, videos under 350MB
  • Check format - JPG, PNG, GIF for images; MP4, MOV for video
  • Try refreshing - Connection issues can interrupt uploads
  • Ensure video uses H.264 codec
  • Try re-encoding with a tool like HandBrake
  • Verify the file isn’t corrupted
Each platform crops to its preferred aspect ratio. Use the image editor to crop to the right dimensions before publishing, and preview to see exactly how it will appear.
