LinkedIn is a key platform for professional communication, announcements, and personal branding. To ensure that all users can access your content, it’s important to follow a few basic accessibility practices when posting images and videos.
Image Posts
Images on LinkedIn support alt text, which allows you to provide a written description of the image for screen reader users. LinkedIn does not currently generate alt text automatically, so it’s up to you to add it when uploading an image.

Tips for Writing Good Alt Text
- Be concise and specific—describe what matters in the image.
- Include context where relevant (e.g., “Team presenting at annual strategy meeting”).
- Skip redundant phrases like “image of”—screen readers already indicate that.
- If the image is decorative or purely aesthetic, it can be left without alt text.
Video Content
LinkedIn supports automatic captions for uploaded video content, which can be edited before publishing to ensure accuracy. Captions are essential for users who are deaf or hard of hearing, and they also help improve engagement for all users—especially those watching without sound.

Other Considerations
- Avoid text-only images—key information should be in real text, not just baked into a JPEG of a chart.
- Use readable fonts and high-contrast colors in any graphic content.
- Keep captions on-brand, but functional—“thrilled to share” can stay, but make sure the content is actually shareable for everyone.
- Don’t forget document attachments—LinkedIn allows uploading PDFs and other files. These should also be accessible, with tagged headings and selectable text. See this site’s section on PDF accessibility for more info.
