How To Post On LinkedIn

Any great LinkedIn profile is fed by content. Content is the best way for people outside your network to find you and learn about who you are. The List of content you can post on LinkedIn has grown massively over the years. So, here is an easy step-by-step guide to posting on LinkedIn. 


You can upload single images with a maximum file size of 5MB. A moderator of LinkedIn stated the ideal image size is 552 pixels wide by 368 pixels tall (or an aspect ratio of 3:2). If the image is larger then the image will be centred and cropped. This is especially important if you have any text in your image, as important letters could be cropped out of the final result. 

You can also upload multiple images at once. The limit is 9 for any single post, but there is a lot you can do with those 9 images. I’ve seen marketeers use them for 8 step guides, panoramic views of a building and even creative members using the carousel to lengthen their arms like a comic book villain. 

To share a Photo head over to your feed, click on the Photo icon. Choose the photo or photos you want to upload, add your caption in the text box and post. 



A natively uploaded video will always perform better than a link. LinkedIn prefers it when you keep people on their platform. So, by uploading a video to LinkedIn rather than uploading somewhere else you’ll be able to have much greater reach for your content. 

One of the main reasons why a video won’t post is the file type isn’t supported.

LinkedIn supports the most common video formats such as MP4, MPEG-1, MKV and WebM. 

But, LinkedIn doesn’t support AVI, MPEG-2, Raw Video WMV1, Quicktime or .MOV. 

For the full list of supported file types and codecs you can visit this troubleshooting guide. 

The maximum file size you can upload is 5GB, which means you have a lot of room for your files to work with. 

The minimum duration your video has to be is 3 seconds and the maximum duration for your video is 10 minutes. So, you can’t upload full 30 minute TED talks or 2 second gifs. But, everything else is up to your creativity. 

Sharing a video is very similar to a photo. Click on the Video icon, choose your video file, caption and post. 


Uploading documents is one the latest additions to LinkedIn’s content ability with members now able to upload powerpoint presentations, PDFs and word documents. Fantastic for CV’s, product highlights and design. 

A few quick tips for documents: 

  • The file size cannot exceed 100MB
  • You cannot exceed 300 pages, or slides
  • You can only edit the description of your document after posting not the document itself 
  • Members that can view your post will be able to download your document as a PDF. 

To upload a document click on Start a post from your feed, click on the document icon, choose your file and add your description. Finally click post! 

LinkedIn has multiple tools you can use to grow your engagement, connections and most importantly achieve more clients.
