Alternative text explains meaningful Google Docs images to readers who cannot see them. Describe the information or purpose the image contributes, rather than merely repeating that it is an image.
Add or revise the description
- Select the image, drawing, or graphic.
- Open Image options > Alt text.
- Enter a useful description.
- Use the advanced title option only when it adds value, then review the saved wording.
The official guidance also lists platform-specific shortcuts for opening alternative-text settings. Check the command for your keyboard if you prefer to work without the mouse.
Describe the relevant meaning
For a diagram, explain the important relationship. For a screenshot, identify the control or state that the article discusses. For a chart, provide the key trend and make essential values available in text or a suitable table.
A long visual report may need a detailed explanation in the body rather than an enormous alt-text field. The description should help the reader access the content, not become a hidden substitute for necessary prose.
Check accuracy after image changes
Some images receive automatic alternative text. Google recommends checking that it is correct. Do not assume a generated description identifies the right product, person, or chart conclusion.
Update the text after replacing or materially cropping an image. Also inspect the final delivery format and accessibility workflow rather than assuming all exported files retain every feature identically. Keep private information out of descriptions as well as visible images, and ensure the wording remains consistent with the document’s actual claims and the audience’s needs.
