What LinkedIn alt text is (and who hears it)
LinkedIn alt text gives someone listening to a feed photo or article image the information a sighted reader gets from it. It usually stays out of the visible post. Your caption can introduce an idea or invite discussion; the alt text explains the image supporting that idea.
For a headshot, identify the person only when you know their name and that identification matters. For a product demonstration, describe the action. One precise sentence is more useful than a string of promotional adjectives. Do not infer a person’s identity, emotions, or job from appearance alone.
LinkedIn alt text character limit: API maximum vs recommendation
Hard max vs recommended length
The 4,086-character ceiling belongs to the documented Images and MultiImage API altText fields. LinkedIn Help publishes no in-app character limit. LinkedIn Help publishes no in-app character limit. The recommendation is fewer than 120 characters. LinkedIn Images API and LinkedIn MultiImage API support these numbers; LinkedIn Help does not give a separate in-app maximum.
Why Handykit targets 80–125 characters
A short draft gives you room for a subject, an action, and a distinguishing detail. The upper end of Handykit’s range exceeds LinkedIn’s recommendation, so shorten it before pasting. Count spaces and punctuation too. A short image description is a starting point, not a reason to remove information essential to understanding a chart.
For a dense dashboard, describe the takeaway in the alt text and put supporting figures in accessible post text. Check every number against the original. A draft that fits the counter but reverses a trend is less useful than a slightly longer accurate sentence.
How to add alt text on LinkedIn desktop
- Upload the image to your post or article.
- Click Alt.text below the image.
- Write or paste the description, checking it against the photo.
- Click Save, then finish reviewing your post.
These labels follow LinkedIn Help. Save the image description before publishing the post. If you replace or crop the image, revisit the description so it still matches what readers receive.
How to add alt text in the LinkedIn mobile app
- Upload your image in the LinkedIn app.
- Tap ALT below the image.
- Enter your description and tap Done.
- Review the image and caption together before sharing.
A phone preview can hide small chart labels. Zoom into the original before describing figures, dates, or names. Keep the alt text focused on information a reader would otherwise miss.
Does LinkedIn auto-generate alt text?
LinkedIn may assign a description when you leave the field empty. LinkedIn Help says desktop uploads receive an alert when this happens; mobile uploads do not. Silence on your phone therefore does not establish that the image lacks an automatic description.
Custom wording lets you explain the relevant detail instead of relying on object recognition. Compare any generated draft with the actual picture: check company names on a sign, the direction of a line chart, and which object is the subject. Keep marketing language in your caption.
Multi-image and carousel posts
The LinkedIn MultiImage API documents sets of 2–20 images and per-image altText values. Give each photo its own description, rather than repeating one sentence for the whole set. This API evidence concerns image collections, not every format people call a carousel.
In an event sequence, one photo might show the speaker and another the audience exercise. Describe the difference. If a set tells a sequence, make each description intelligible in order. Do not assume an uploaded PDF document has the same editing controls as a multi-image post.
LinkedIn alt text examples
Illustrative examples follow; use them only when their details match your actual image. Counts include spaces and punctuation.
- Founder headshot:
Founder Mira Chen wearing a navy jacket, seated beside a window in the workshop.
(80 characters) - Product:
Black task lamp with an adjustable arm illuminating an open notebook on a wooden desk.
(86 characters) - Chart:
Line chart showing support response time falling from 14 hours in May to 6 hours in June.
(89 characters) - Event:
Three speakers answering audience questions on a conference stage beneath a green banner.
(89 characters)
These examples name visible content without starting with “image of.” The chart includes its message, not just “a graph.” The event description avoids guessing who the speakers are. Replace sample names and figures with verified details; if a name adds no useful context, describe the subject without it.
Alt text limits compared
Field capacity and writing advice answer different questions. API limits apply to API fields; they do not establish an undocumented in-app maximum.
| Platform | Documented maximum | Writing guidance and source |
|---|---|---|
| 4,086 characters (API) | Under 120 recommended; LinkedIn Images API | |
| Shopify | 512 characters | 125 or fewer recommended; Shopify Help: adding alt text |
| Etsy | 250 (Etsy Help guidance; no published hard max) | Keep it concise; Etsy Help: listing image alternatives |
| 500 characters | Describe what is visible; Pinterest Help: alternative text | |
| 1,000 characters (API) | No in-app cap confirmed; Instagram Graph API: media |
See the full alt text character-limit guide. Handykit’s 80–125 character target is a drafting preference, not an accessibility standard.
Review the draft in context
Alt text conveys the information an image adds to the surrounding page. The W3C WAI Images Tutorial distinguishes informative, decorative, and complex images: a product photo needs a useful description, while a chart may also need a fuller explanation nearby.
Describe visible details in ordinary language. Google Search Central image guidance advises useful, contextual descriptions instead of keyword stuffing. That guidance concerns Google image search; it does not promise better reach inside a social platform.
