Downloads are appropriate when the reader needs a printable, portable or formally issued document. They should not replace accessible web content or become an unmanaged archive of outdated files.
In brief: Publish a download only when its format serves a real task and the business can keep the file accessible, current and free of unintended data.
Choose HTML or a file deliberately
| Use case | Preferred format | Reason |
|---|---|---|
| Ordinary guidance | HTML page | Searchable, responsive and easier to update |
| Printable form or formal document | Accessible PDF plus explanatory HTML | Preserves a controlled document while keeping context available |
| Data for reuse | CSV or suitable structured format | Easier to process than a PDF table |
| Large reference pack | Organised download with version information | Supports offline use when justified |
Manage every file as content
Give the file a descriptive name, title, owner, publication date, review date and replacement process. Display file type and approximate size before the link. When a file changes, decide whether its URL should remain stable or the old version must stay available.
Protect accessibility and privacy
Use real headings, tagged structure, selectable text, meaningful reading order and accessible links. Do not publish scanned images as the only version. Remove hidden comments, revision history, author metadata and personal data that should not be public.
Secure uploads and storage
Documents supplied by users require strict file-type, size and malware controls. Store them outside public executable locations and restrict access. Public downloads should not reveal private directory structures or predictable confidential filenames.
Acceptance test
Open the file on desktop and mobile, with keyboard and a screen reader where relevant. Check the link, filename, size, metadata, print result and version. Search the site for references to the old document before replacement.
Example: an old price list remains discoverable
A new PDF is uploaded with a different filename, but search engines and old articles still link to the previous version. Customers find conflicting prices. Use a document register, stable replacement strategy and a search for old references. Where history must remain public, label archived versions clearly instead of leaving them ambiguous.
What the business should retain
- Document owner and review date
- Accessible source and final file
- Public URL and replacement rule
