How to make a PDF accessible to screen readers
Open your PDF in Check PDF accessibility, choose Add tags, check the headings, paragraphs and reading order it proposes, and download. A screen reader follows a PDF’s tags; without them, it guesses the order.

Tag a PDF in six steps
- Run the check. Choose your PDF in Check PDF accessibility, then Check accessibility.
- Choose Add tags. Every part is numbered on the page in reading order.
- Check each part. Change what it’s Read as, move it, or choose Leave out, starting with any marked A guess.
- Set the Language. It picks the voice a screen reader uses.
- Choose Write tags. The tags are written into the file.
- Download the PDF. The tags are saved in it.
Good to know
- Have a person review it. Tags are guessed from the layout, so a numbered heading can merge with its sentence.
- Describe gives a picture words instead of “graphic”.
- Label names a form field.
- A missing title is offered from the first heading.
- Add form fields first? Make the form fillable before you tag it. Everything starts at pdfeditor.page, and there are 45 single-purpose tools at pdfeditor.page/tools.
Questions
What can the check not tell me?
Whether each description fits its picture, the reading order is right, the contrast is enough and each tag says the right thing: a person has to judge those.
Can it fix a PDF that already has tags?
It keeps the tags a PDF already has, and you can still describe a picture that has none.
