Uploading Documents

How to upload PDFs, web pages, and other content for accessibility scanning.

Supported File Types

Adaline supports accessibility scanning for:

  • PDF documents -- The most common format for accessibility audits
  • Web pages -- Enter a URL to scan any publicly accessible web page
  • Microsoft Office documents -- Word (.docx), PowerPoint (.pptx), Excel (.xlsx)

Uploading a PDF

  1. Click New Scan from your dashboard
  2. Select Upload PDF and choose your file, or drag and drop it into the upload area
  3. Add an optional label to help you identify the document later
  4. Click Start Scan

File Size Limits

  • Maximum file size: 50 MB per document
  • Maximum page count: 500 pages per document
  • For larger documents, consider splitting them into sections

Scanning a Web Page

  1. Click New Scan from your dashboard
  2. Select Web Page
  3. Enter the full URL (including https://)
  4. Click Start Scan

Adaline will load the page in a headless browser, render all dynamic content, and analyze the final DOM for accessibility issues.

Batch Uploads

For scanning multiple documents at once:

  1. Navigate to Scans in the sidebar
  2. Click Batch Upload
  3. Select multiple files or drag and drop a folder
  4. All documents will be queued and processed in order

You'll receive a notification when each scan completes.

Scan Status

Each scan goes through these stages:

StatusDescription
QueuedWaiting to be processed
ProcessingCurrently being analyzed
CompleteReport is ready to view
FailedAn error occurred during scanning

If a scan fails, check that the file is not corrupted or password-protected. You can retry failed scans from the scan details page.

Tips for Better Results

  • Use the original document -- Scanned images of printed documents won't produce useful results. Upload the source digital file when possible.
  • Ensure PDFs are not image-only -- If your PDF is just a scanned image, Adaline can only check limited structural elements.
  • Check that web pages are publicly accessible -- Adaline cannot scan pages behind authentication walls.
