Hey Product Hunt! 👋
Happy to share PDF Accessibility Checker by WebYes with you!
Checking a PDF for accessibility can leave you wondering what the errors mean, where they are, and how to fix them. We built this tool to help you work through those questions, with detailed results and practical guidance available for free.
Upload a PDF or paste a public link, and you can:
Prioritize the fixes: Review issues by severity to decide what needs attention first.
Locate problems without searching through pages: Select a finding to see the affected content highlighted in your PDF.
Understand what to change: Get explanations and fix instructions you can follow in your document editor.
Work through the human checks: Review flagged findings and follow instructions for recommended manual checks.
Who is it for?
Content and marketing teams: Check reports, brochures, and guides before publishing or sharing them.
Designers and document creators: Check an exported PDF, make changes in your source file, and scan the updated version.
Web teams and agencies: Paste links to published PDFs to identify accessibility issues and plan the fixes.
It supports PDFs up to 50 MB, with no software to install, no account to create, and no email required. Your PDF is not stored.
Have a document you’re working on? Give it a try and tell us how it fits into your workflow.
We’d love to hear what helped, what felt confusing, and what you’d like to see next. We’ll be here in the comments to answer questions and clarify any findings or instructions you’re unsure about.
@anjaly_rose Free, no sign-up, no files stored, and it flags what needs a human to review instead of pretending everything is automatable. That's rarer than it should be. We have a stack of old PDFs that nobody has ever checked against WCAG, so this is going straight into my Monday. Nice work, team.
@upasana_sahu Thank you! If anything in the findings needs explaining, drop us a question. Happy to help!
Nice work! Accessibility checks usually just dump a list of errors, so seeing them marked on the page is a real upgrade. Does it catch scanned PDFs too?
Thanks, @elene_tandashvili Yes, you can upload scanned PDFs. For image-only files, the results are limited to what the checker can assess from the images. Checks for document structure, such as headings and tags, need a PDF with recognized text and tagging.
Nice, no sign-up is a big plus. Does it also work with scanned PDFs?
Thanks, @ayberkbozkus Yes, you can upload scanned PDFs. For image-only files, the results are limited to what the checker can assess from the images. Checks for document structure, such as headings and tags, need a PDF with recognized text and tagging.
Very easy to use. Intuitive design. Does it support WCAG level AAA?
Thanks @deethul , glad you find it easy to use!
The checker tests against WCAG 2.1 Level AA and PDF/UA, but it doesn't cover Level AAA.
Does it catch tagging and reading order, or mostly what’s visble on the page???
Good question Jean Bonnenfant. It goes well beyond what’s visible on the page.
Tagging
This is at the core of the scan. Each PDF is validated against the PDF/UA standard, which checks the tag structure behind the page—the part screen readers actually use. It checks for:
Documents that aren’t tagged at all, or content left outside the tags.
Broken or invalid tag structure.
Headings that skip levels, such as H1 straight to H3.
Lists and tables that aren’t marked up correctly, such as tables without header cells.
Images and figures with no alternative text.
It also checks things you can’t see on the page at all, like the document title, language settings and font/text encoding. Wherever an issue can be pinpointed, it’s highlighted on the page, so you can see exactly what to fix and where.
Reading order
This isn’t checked automatically. A tool can confirm that content is tagged, but not whether the order of the tags makes sense to a reader, because that depends on the layout and meaning of the document.
Reading order appears in the report as a manual check, so you can confirm it yourself—for example, by reading the document with a screen reader.
The scanner covers the structure and tagging side automatically and clearly tells you which checks, like reading order, need a human to confirm.
Hey Product Hunt 👋 I’m Lukhman, the designer on this.
Most PDF checkers I tried while researching gave you a long list of rule IDs and left you to work out where each problem was and what to do about it. We designed the results screen around three questions anyone fixing a document has:
What should I fix first?
Where is the problem?
How do I fix it?
I’d love feedback on the experience. Was anything in the results confusing, or was something missing that would help you fix a document? I’ll be here all day 🙌
Congratulations on your launch. You've got my upvote with all privacy checks - "Completely free, with no sign-up, no email required, and no files stored. Checks against WCAG 2.1 AA and PDF/UA".
When something is completely free with no paid upgrade tiers, my question is why and how do you make a profit or cover costs?
@richatsealedvault Thank you for the support! And that’s a fair question. We want accessibility checking to be accessible to more people, which is why this tool is free.
Our revenue comes from other paid WebYes products with more extensive features. That helps us cover costs and offer tools like this without charging for them.
@anjaly_rose Aww thank you for freely sharing a piece of your success with the world.
