How to check a PDF for accessibility
- Drop your PDF on the page or choose it from your device.
- Press Check my PDF.
- Read the list: each problem comes with one line on what to do.
- Fix the file at its source, export it again and check once more.
What the checker looks at
- Tags: the hidden structure that lets a screen reader read headings, lists and tables in order.
- Language: the document language, so a screen reader uses the right voice.
- Title: the name shown in the window and read out when the file opens.
- Real text: a scanned page is only a picture and a screen reader cannot read it.
- Bookmarks for long documents, descriptions for images, and labels for form fields.
How to fix what it finds
- Set the title and the language in the properties of the PDF in a PDF editor.
- Add tags, headings and image descriptions in the program that made the file, such as Word or InDesign, before you export to PDF.
- For a scanned PDF, run text recognition (OCR) so that the pages contain real text.
Good to know
This is a quick check of the basics and not a certificate. It does not check reading order, colour contrast or table structure, which need a person to look. Public bodies and many employers must provide accessible documents, so a pass here is a good first step. Your PDF is checked in your browser and never uploaded.

Questions
Is my PDF uploaded?
No. Everything runs in your browser.
Does a pass mean my PDF is accessible?
No. It means the basics are in place. Reading order, contrast and tables need a person to look.
How do I fix the problems?
Set the title and language in a PDF editor, and add tags and image descriptions in the program that made the file (Word, InDesign) before exporting.
