Get a link
Publish this page to a Display URL that you can send to anyone.
- Anyone with the link can open it for 30 days. Search engines do not index it.

Nothing leaves your browser until you select Get a link. Do not publish passwords, keys or personal data.
How to use the HTML viewer
- Paste HTML into the source box, or drop an .html file on it. To see how the tool works, select Load an example.
- Read the rendered page in the preview. Select Phone, Tablet or Desktop to change the width. Select Dark to see the page in a dark color scheme.
- To send the page to someone, select Get a link. Display publishes the HTML and gives you a URL and a claim link.
Limits
- The tool renders and publishes up to 5 MB of HTML. For files up to 50 MB, publish with the Display CLI.

- Images, styles and scripts load only from full URLs. Relative paths to files on your computer do not load.
- Links in the page open inside the preview frame.
- Get a link makes a public link. Anyone with the URL can open it for 30 days. Search engines do not index it.
HTML viewer questions
Does the HTML viewer send my file to Display?
No. The page renders in your browser. Display receives the HTML only when you select Get a link.
Is it safe to open HTML from someone else here?
The viewer runs the HTML in a sandboxed frame with its own origin. Scripts in the HTML can run, but they cannot read your display.dev session, cookies or storage, and they cannot open new windows or submit forms. They can still load files from the web, so do not paste HTML from a source that you do not trust.
How long does the link work?
30 days. Open the claim link and sign in to keep the page in your Display organization. After you claim it, you can make it open only for people at your company.
Can I change the page after I get a link?
Get a link makes a new URL every time. To update one page at the same URL, claim it first. Then publish the update from your Display account or let your agent do it.
Let your agent publish the next one
