PDF Accessibility Remediation

Make a PDF friendlier to screen readers: tag its structure and reading order, set the document language, and add alt text to images — right here in your browser, nothing ever uploaded.

✓ No file-count or file-size limit ✓ Nothing ever uploaded ✓ 100% free

1. Choose your PDF

2. Document language

Screen readers use this to choose the right pronunciation and voice.

This PDF has no title set in its metadata, which screen readers also rely on. Consider setting one with Edit Metadata too.

3. Review images

Add a short description for each image, or mark it decorative if it's just visual flair (like a divider line or background flourish) — decorative images are tagged so screen readers skip them instead of announcing nothing useful.

✅ Done.

    Honesty note: this is a genuine baseline remediation pass, not a full manual accessibility certification. Reading order follows the order content was originally drawn in the file, which matches visual reading order for the vast majority of ordinary documents but may not be perfect for complex multi-column layouts. Only real embedded images get alt-text tagging (a rarer image format used directly inline in the page data isn't covered). For anything legally or contractually required to meet a specific accessibility standard, treat this as a strong starting point and have it reviewed with a dedicated accessibility checker before relying on it.

    What does "accessibility remediation" actually do to my PDF?

    It adds information that's invisible when you look at the page but that screen readers and other assistive technology rely on: a document language, a reading-order structure, and text descriptions for images. The PDF looks completely unchanged visually.

    Does this make my PDF officially PDF/UA or WCAG certified?

    No — those are formal standards with requirements beyond what any automated tool can fully guarantee (things like verified table headers, form field labels, and manual review of reading order for complex layouts). This tool covers real, meaningful ground toward that — structure tagging, language, and image descriptions — as a strong starting point, not a substitute for a full accessibility audit on documents where formal compliance is required.

    What's the difference between adding alt text and marking an image decorative?

    Alt text is announced by a screen reader in place of the image, so use it for anything that conveys information (a chart, a photo, a diagram). Decorative marks an image as pure visual styling with nothing to announce — think a divider line or a background flourish — so it's tagged to be skipped entirely instead of interrupting the reading flow with something like "image."

    Why does the document language matter?

    Screen readers use it to choose the correct pronunciation rules and voice — without it, a document can be read aloud with the wrong accent or mispronounced words, even if every word is spelled correctly.

    Is my file ever uploaded?

    No, the whole process — reading the PDF, reviewing images, and applying the changes — runs entirely in your browser. Nothing is ever sent anywhere.

    Is there a file size limit?

    No hard file-count or file-size limit is enforced — very large or complex documents are limited only by your device's available memory, since everything is processed locally.
