Why Decorative Images Should Be Hidden with ARIA-Hidden
Introduction
As websites continue to evolve with more dynamic, image-rich designs, accessibility must remain a top priority. While imagery enhances visual appeal and user experience, not every image contributes meaningful information. In fact, many are purely decorative. These decorative images, if not marked correctly, can clutter screen reader output, confuse users of assistive technology, and degrade the overall usability of a website.
That’s where accessibility techniques like aria-hidden="true" come into play.
In this blog post, we'll explore why decorative images should be hidden using ARIA attributes, how this practice supports digital accessibility, and how tools like allyWay—a scalable, AI-powered accessibility solution—can help organizations improve inclusion while saving time and resources.
Understanding this best practice is essential not only for meeting standards such as WCAG, EN 301 549, the European Accessibility Act (EAA), and the ADA—but also for designing digital spaces that truly cater to everyone.
Let’s dive into the importance of properly handling decorative images and how to set your website up for accessibility success.
What are Decorative Images?
Decorative images are visual elements that do not convey important information or meaning. They're often used to enhance aesthetics, create mood, or provide visual separation between sections.
Common Examples of Decorative Images
- Background patterns and textures
- Icons used solely for design purposes
- Divider lines or borders
- Stock images that don’t add content value
- Transparent spacers or placeholder images
- Decorative quotes or symbols with no semantic meaning
Essentially, if removing the image doesn’t subtract from the content’s clarity or usefulness, it’s likely decorative.
Why Decorative Images Can Impact Accessibility
Screen readers and other assistive technologies interpret digital content linearly. That means every image with an "alt" attribute—or one missing proper labeling—will be announced to the user. Decorative images, when not marked correctly, can cause several problems:
1. Disrupts User Experience
Imagine listening to a screen reader describing every abstract shape or visual flourish with no meaningful relevance. It can become frustrating and confusing for users with vision impairments.
2. Increases Cognitive Load
More content for screen readers means more time, more distractions, and a higher chance of users disengaging. Excessive or irrelevant details ruin the streamlined experience users need.
3. Fails Accessibility Standards
According to the Web Content Accessibility Guidelines (WCAG) 2.1 and upcoming WCAG 2.2 or 3.0, content should be perceivable, operable, understandable, and robust. Improperly marked decorative images violate these principles.
4. Creates Legal Risks
While no solution can guarantee legal compliance, neglecting accessibility risks unwanted attention. Marking decorative images correctly is one of many proactive steps that support legal protection efforts.
Why Use aria-hidden="true"?
The ARIA (Accessible Rich Internet Applications) specification helps developers make dynamic content and user interface components more accessible to people with disabilities.
aria-hidden="true" is a powerful attribute. When applied to an element:
✓ It tells assistive technology to ignore that element
✓ The element does not appear in the accessibility tree
✓ It is completely skipped by screen readers
Proper Usage Example
<img src="decorative-stars.png" alt="" aria-hidden="true">
Here, both alt="" and aria-hidden="true" reinforce the signal: “This image is not important for screen reader users.”
Using both attributes redundantly ensures that if one method fails (due to user settings, browser issues, or device limitations), the other still supports the intended goal.
Comparing Accessibility Approaches for Decorative Images
Let’s look at how different techniques stack up:
| Technique | Screen Reader Friendly | Recommended Use | Notes |
|---|---|---|---|
alt="" |
✓ | Highly Recommended | Best for simple decorative <img> tags |
aria-hidden="true" |
✓ | Supplementary | Ideal for additional safeguard |
Missing alt |
✗ | Not Recommended | May be treated as meaningful content |
| Invalid ARIA Usage | ✗ | Not Recommended | Poor syntax causes more harm |
Using both alt="" and aria-hidden="true" on decorative <img> elements is a best practice for robust accessibility.
Accessibility Guidelines and Standards
Understanding which standards motivate this practice helps clarify its importance.
WCAG (Web Content Accessibility Guidelines)
Under WCAG 2.1 Guideline 1.1 – Text Alternatives, decorative images should be given:
→ Empty alt attribute (alt="")
→ Or marked with aria-hidden="true"
This prevents them from being included in accessibility APIs.
EN 301 549 & European Accessibility Act (EAA)
EU standards require that websites and mobile apps be accessible to all users, including people with disabilities. Proper labeling of decorative images contributes to meeting these expectations.
ADA (Americans with Disabilities Act)
While the ADA doesn't define technical standards, court rulings often refer to WCAG as a benchmark. Marking decorative images correctly aligns with the principles of equal access.
Important Note: While following these practices reduces legal exposure, tools alone cannot guarantee ADA or WCAG compliance.

Best Practices for Implementing ARIA-Hidden
Here’s how to implement aria-hidden="true" effectively:
✅ DO
- Use it for purely decorative elements
- Combine with empty alt attributes for
<img>tags - Test with screen readers (NVDA, JAWS, VoiceOver)
❌ DON’T
- Use it on meaningful images or content
- Assume it's a shortcut—context still matters
- Apply it to entire parent containers with interactive elements
Bonus Tip:
Use semantic HTML and only add ARIA where necessary. Avoid "ARIA hell" by keeping markup clean and intentional.

FAQs About ARIA-Hidden and Decorative Images
Q: Is using alt="" enough for decorative images?
A: For regular <img> tags, alt="" is typically sufficient. However, using aria-hidden="true" in combination is a redundancy that adds protection across all assistive tech.
Q: Do background images need ARIA attributes too?
A: No. Background images in CSS are not read by screen readers and are implicitly decorative. No ARIA or alt text is necessary.
Q: Can I use aria-hidden="true" on non-image elements?
A: Yes. Any HTML element that should be hidden from assistive technology (graphics, icons, symbols) can be marked this way—just ensure they’re truly non-essential.
Q: Does allyWay fix image accessibility issues automatically?
A: allyWay helps improve accessibility through audits, suggestions, and supported functionality—but no platform can guarantee legal compliance. allyWay supports your accessibility efforts by removing barriers and strengthening your accessibility infrastructure.
