FixFixes by the rules
- Labels
- Every part of the page says what it is
- Reading order
- The order a screen reader reads the page
- Headings
- In order, with none skipped
- Lists and tables
- Items, rows and headers
- Fonts
- So every word can be read aloud
First we check your PDF, then we fix it. Here's what happens at each step, what Claude does, and what we can't fix for you.
Upload Check Fix Download
We check your file against the PDF/UA standard, using the version it says it follows or the one you pick. Every problem gets a short name, a count of where it happens, and the accessibility guideline it affects.
Checking is part of every plan and doesn't use any of your pages.
| Rule | What we tell you | WCAG |
|---|---|---|
| 5 | The file doesn't say it's accessible | 4.1.2 |
| 6.2 | The file doesn't say it's marked up | 1.3.1 |
| 7.1 | Text isn't marked up for screen readers | 1.3.1 |
| 7.1 | The document has no title | 2.4.2 |
| 7.1 | The window shows the file name, not the title | 2.4.2 |
| 7.2 | The language isn't set, or some text can't be read aloud | 3.1.1, 1.3.1 |
| 7.3 | Images have no description | 1.1.1 |
| 7.4 | Headings are out of order | 1.3.1, 2.4.6 |
| 7.5 | Tables have no headers | 1.3.1 |
| 7.7 | Math has no description | 1.1.1 |
| 7.9 | Notes aren't marked up | 1.3.1 |
| 7.18 | Links, form fields or comments aren't marked up | 4.1.2, 2.4.4 |
| 7.20 | Embedded content can't be checked | 1.3.1 |
| 7.21 | Some fonts can't be read aloud | 1.3.1 |
The numbers are sections of PDF/UA-1, and each covers several checks.
Most fixes follow the standard to the letter. A few need judgment, like what an image shows, and Claude handles those. You don't need to answer anything.
You get the fixed PDF and a list of every change. The ones Claude made are marked AI.
Only what it needs for each job, never your whole file. Claude is made by Anthropic.
The image, cropped, and the text near it.
Short snippets of the hidden text.
A picture of one page, with the paragraphs we found on it.
The opening text of the document.
A few problems need the original file or a PDF editor, like fonts that were never included in the PDF. We fix everything else, then tell you what's left and how to fix it yourself.
