Run local preflight to generate your readiness score, summary counts, and finding-by-finding guidance. Optional AI review appears after you analyze an image.

Visual accessibility

Measure WCAG contrast in your browser. Does not change your readiness score or call AI.

Color sampling and contrast calculations run in your browser. Image pixels are not sent for contrast measurement.

Human review

Visual design checklist

Not automatic pass/fail—answer honestly before you publish.

  • Is important meaning conveyed by color alone?

  • Is text placed over a busy photo, gradient, or texture?

  • Is critical text small or thin in the image?

  • Is essential text only inside the image (not in caption)?

  • Would the message still make sense in grayscale?

Visual summary

Measured contrast plus human review prompts and optional AI observations.

    Not measured as WCAG pass/fail

Measured ratios apply to solid foreground and background colors. This tool supports preflight review, not legal WCAG certification.

This is an approximation for accessibility review. Actual output varies by platform, browser, operating system, assistive technology, and user settings. This is not an exact screen reader simulation.

    How to apply this on Instagram

    1. Create your post and add your image.
    2. Before publishing, open Instagram's alt-text or accessibility option for the image.
    3. Paste or enter your prepared description and review it.
    4. Complete your caption and hashtags.
    5. Review the post in the composer before publishing.

    Social platforms update their interfaces regularly. If the option appears in a different location, look for Alt Text, Alternative Text, Accessibility, Edit Photo, or Image Description controls.

    Instagram capabilities
    • Alternative text on images: supported — Supported in many posting workflows; exact controls vary by device, post type, and app version.
    • Multiple images: varies — Review each meaningful image when publishing carousels.
    • Video captions: supported — Instagram has supported automatically generated captions for video; review for accuracy when publishing video.
    • Automatic captions: supported — Auto-generated captions may need review; video analysis comes in Phase 6.
    • Manual caption upload: varies — Varies by workflow.

    Video Accessibility Checker — transcripts, timed captions, and SRT/WebVTT export for MP4/WebM.

    Alt text

    When publishing, use Instagram's available alt-text or accessibility option to add or review the image description.

    Meaningful content

    Describe meaningful content, not only aesthetics. Include essential text shown in the graphic.

    Promotional details

    Ensure dates, prices, and offers are not accessible only visually.

    Accessible Content Preflight is an independent tool and is not affiliated with Instagram, Facebook, LinkedIn, or X.

    Before you publish

    Session-only confirmations—the tool cannot verify actions inside social apps.

    Final checklist

    Ready to publish on Instagram?

    Important items still need attention

    2. Copy your final caption from the workspace
    3. Copy alt text or image description
    4. Apply accessibility fields in the platform composer
    5. Review the post once more before going live

    Controls and labels can vary by post type and app version—confirm in Instagram's publishing UI before you ship.

    Accessibility preflight report

    Generate a client-ready report from checks already run in this browser session. Export does not call AI or upload content.

    Privacy & export options

    No AI remediation has been generated for this session. Generate guidance in Fix Lab or the relevant checker tool first.

    Run at least one preflight check (caption, contrast, AI, screen reader preview, or video captions) to generate a report.

    Final caption

    Edit after applying fixes, then copy for publishing. Re-run preflight if you change content.

    Instagram FAQ

    Based on current platform help documentation and accessibility best practices.

    • Can I prepare Instagram alt text here?

      Yes. This tool helps you draft and review alt text before you add it in Instagram.

    • Does this tool publish to Instagram?

      No. You copy prepared content and publish in the Instagram app or website.

    • Does this guarantee ADA compliance?

      No. It supports preflight review only.

    • Can it analyze text inside my image?

      Optional AI image review may detect visible text, but you should verify accuracy. Contrast tools measure colors you sample or enter.

    Platform guidance last reviewed 2026-10-08. UIs change; verify steps in the official app before publishing.

    What this tool checks

    • Caption and alt-text heuristics for feed posts
    • Platform-specific publishing confirmations
    • Visual contrast and screen reader preview (local)

    What it does not do

    • Verify controls inside the Instagram app
    • Guarantee platform UI labels match your device
    • Replace human review before you tap Share

    Automated accessibility guidance is not legal advice or certification. Some criteria require human review in the native app.
