Sparkforge Social Planner can publish PDFs to LinkedIn as carousel or document posts — one of the most engaged formats on the platform. You can also import a PDF and convert each page to a separate image for use on Instagram and other networks.

Create a LinkedIn carousel or document post

  1. Go to Marketing > Social Planner.
  2. Connect your LinkedIn account (Page or profile).
  3. Click New Post to open the post composer.
  4. Pick LinkedIn from the socials dropdown and add your post copy.
  5. Click the file upload icon (between the image and video upload icons).
  6. Upload one or more PDFs to post as a LinkedIn carousel, or import images to post as a PDF.
  7. Optionally rename the PDF or add a watermark.

Constraints to know

  • LinkedIn allows up to 300 pages and 100 MB per document.
  • When you import a PDF, Sparkforge converts the pages to images. If Instagram is in the same post, the images are auto-cropped to Instagram's aspect ratio.
  • Hover over a media preview to reveal an X for deletion.
  • If you choose post as a PDF, all uploaded images are converted into a single PDF and posted to LinkedIn.
