What Is Digital Accessibility? Everything With a Screen

Web accessibility is your website. Digital accessibility is your website, your app, your PDFs, your email, your kiosk, and the software your staff use all day.

Last reviewed August 28, 2026

Digital accessibility is the umbrella term. It covers every digital thing your organisation puts in front of a person, whether that person is a customer, a citizen, or an employee.

Most owners meet the idea through their website, discover the term later, and then find out the scope is wider than the thing they just fixed. Better to know the shape of it up front.

The Seven Things It Covers

What digital accessibility covers, and the standard that applies to each

The Part Organisations Forget

Two of those rows catch people out repeatedly.

Documents. A site can pass every check while the price list, the menu, and the annual report hanging off it are untagged PDFs. The law does not care about file format. Our PDF accessibility guide covers what makes a document readable, and our free PDF checker will tell you where yours stands in about ten seconds.

Internal software. Accessibility is usually framed as a customer question, which quietly excludes your own staff. If your HR portal, your rota tool, or your ticketing system cannot be used by a screen reader, you have made a hiring decision without meaning to. This is where a supplier's VPAT earns its keep: ask for one before you buy, not after somebody cannot do their job.

Web Accessibility vs. Digital Accessibility

The terms get used interchangeably and they are not the same size.

  • Web accessibility is websites and web applications. Standard: WCAG.
  • Digital accessibility is everything above. Standards: WCAG for anything with a user interface, plus PDF/UA for documents and EN 301 549 or Section 508 for procurement.
  • Accessibility, unqualified, usually includes the physical world too: buildings, doors, parking, signage. Different laws, different specialists, not our field.

We work on the digital side, and the majority of that work is web and documents.

Where to Start

In this order, because each step makes the next one cheaper:

  1. Start with the website, because it is the highest-traffic thing you own and the most likely to draw a complaint. Our free scan gives you the mechanical picture in minutes.
  2. Then the documents people actually download. Price lists, forms, menus, reports. Not the whole archive, the ones with traffic.
  3. Then the mobile app, if you have one, since it is usually a separate codebase with separate problems.
  4. Then procurement. Start asking vendors for a VPAT before you sign. This is the cheapest step and it stops the problem renewing itself.
  5. Then internal tools, working backwards from whatever your staff use most.

One honest limit

We audit websites, web applications, and documents. We do not test native mobile apps or hardware kiosks, and we would rather say so than take the work and wing it. If that is what you need, ask us and we will point you somewhere that does it properly.

Common questions

What is digital accessibility?
Making all your digital content and tools usable by people with disabilities: websites, mobile apps, PDFs and documents, email, video, kiosks, and internal software. Web accessibility is the largest piece of it.
What is the difference between web accessibility and digital accessibility?
Web accessibility covers websites and web applications. Digital accessibility is the umbrella term covering those plus apps, documents, email, video, kiosks, and internal systems.
Does digital accessibility include PDFs?
Yes, and PDFs are the most commonly overlooked part. A document published on your site is content you published, and the same laws apply. PDFs also have their own standard, PDF/UA, alongside WCAG.
Does digital accessibility apply to internal software?
Yes. Employees with disabilities need to use your systems to do their jobs, and in the US that is employment law doing the work. Section 508 binds federal agencies and the US Postal Service rather than private employers, which is why federal buyers are the ones who ask for a VPAT. Asking your own suppliers for one before you sign is the practical control either way.
