A transparent check, not an automatic certificate
JunoPDF separates what a browser can detect from checks that still require human review and a current standards validator.
Structure and properties
Tags, language, title, headings, tables, figures, formulas, forms and bookmarks.
Reading order
Uses tags when present; otherwise shows a clearly labelled visual estimate.
Reviewable report
Every finding explains the issue, its impact and the next check. The JSON report can be archived or compared.
Why use this tool: Check PDF accessibility
Inspect tags, language, title, headings, tables, forms, formulas and reading order directly in your browser.
Private browser processing
The tool uses the PDF editor and keeps the document on your device. You do not have to wait for an upload or trust a cloud service with the file contents.
Review before download
Review the result before downloading and continue using text, signature, image and page organization tools. Changes are written only when you choose to export a new PDF.
Original and compatibility
Keep a copy of the original when working with important documents. Complex PDFs can contain embedded fonts, layers or restrictions that depend on the software used to create them.
Long and complex documents
Multi-page documents use progressive thumbnails and an automatic mode for large files. Pages do not have to be rendered all at once, which reduces memory use and interface delays. Actual performance depends on the device, file size and graphical complexity of the PDF.
Check before sharing
Before exporting, review the pages and every element you added. The downloaded file is a new copy, which preserves the original and lets you compare the result. For legal or administrative documents, always confirm the required signature type, document requirements and PDF compatibility expected by the recipient.
