Why does the tool say my feed URL is not valid when I copied it from the browser address bar?

The browser address bar shows the page URL, not the feed URL. The feed URL is usually different and ends in /feed, /rss, /atom.xml, or /feed.xml. Look for an RSS icon on the site or check the page source for a feed link.

Can I use a feed that is behind a login or on my local computer?

No. The tool only accepts public http and https URLs. Private addresses like localhost or internal network IPs are blocked. The feed must be accessible from the public internet without authentication.

My feed is under 5 MB and public, but it still fails. What else could be wrong?

The feed might contain syntax errors, or it might be an HTML page instead of XML. Use the W3C Feed Validation Service to check the feed's syntax. Also make sure the feed URL does not redirect to a different domain or protocol.

Will the PDF include images or the website's design?

No. The PDF contains only the 25 most recent items with title, author, date, and a plain-text summary. HTML tags and images are stripped. The tool does not reproduce the site's layout or visual style.

"Doesn't Look Like a Valid RSS or Atom Feed": How to Fix It

"That URL doesn't look like a valid RSS or Atom feed" means the tool found no readable feed at the address you gave it. The most common cause of this not a valid rss feed error is pasting a homepage URL instead of the actual feed URL. Getting past it takes two minutes.

Check If You Used a Page URL Instead of a Feed URL

A feed is an XML file, not a regular web page. Paste a site's main URL (like https://example.com) and the tool will not find the feed. You need the specific URL that points to the RSS or Atom XML file.

Common feed URL paths include:

/feed
/rss
/atom.xml
/feed.xml

If a blog lives at https://blog.example.com, try https://blog.example.com/feed or https://blog.example.com/rss. Many sites also embed a feed link in their HTML source. Right-click any RSS icon on the page to copy the feed URL directly.

Verify the Feed Format

The tool accepts RSS and Atom feeds. Both are XML, but they use different root elements. RSS feeds begin with an <rss> element. Atom feeds begin with an <feed> element. If the URL returns HTML, JSON, or plain text, the tool rejects it.

Check the Format Manually

Open the feed URL in your browser.
Right-click and select View Page Source.
Look at the very first lines. The document should start with an XML declaration followed by <rss> or <feed>.
If you see <html>, <head>, or <body>, you have a page URL, not a feed URL.

Paste your feed URL into the W3C Feed Validation Service at validator.w3.org/feed. It flags syntax errors and confirms whether the file follows the RSS or Atom specification.

Check for Redirects and Private Hosts

The tool only accepts public http and https URLs. If the feed URL redirects to a login page, an internal network address, or a private host, the request is blocked. This includes feeds hosted behind a VPN or on an intranet inaccessible from the public internet.

Getting an invalid rss feed url error for a feed on a private network means you must make that feed publicly accessible. For public feeds that still fail, check whether the URL redirects to a different domain or protocol. Use curl or open your browser's network tab to see the full chain of HTTP redirects. If the final destination is not a public https URL, the tool cannot reach it.

What to Do If the Feed Is Behind a Redirect

Copy the final URL after all redirects have occurred.
Test that the final URL returns the feed XML directly.
Enter that final URL into the tool.

Consider Feed Size and Server Speed

The tool has a size limit per feed and a fetch time limit. A larger feed will not process. A slow or unresponsive server will time out before the feed downloads.

Download the feed file to your computer and check its size. If it exceeds the limit, reduce the number of items. Most content management systems let you set a maximum post count in the feed.

Load the feed URL in your browser and watch how long it takes to appear. More than a few seconds and the server is too slow for the tool. Host the feed on a faster server or put a caching service in front of it.

Examine Empty Feeds and Feed Not Found

A feed URL can exist, be valid XML, and still contain no items. An empty feed causes an error because there is nothing to render. A feed url returns html when the server sends an error page instead of the feed. This happens when the feed path is mistyped or the site has removed the feed.

To diagnose an empty feed:

Open the feed URL in a browser and check whether any items appear.
Look for <item> (RSS) or <entry> (Atom) elements inside the XML.
No items means the feed is empty. Try a different feed URL from the same site, or contact the site owner.

If you get a feed blocked or empty message, double-check the URL and confirm the site has not moved or deleted its feed. Search the site for "RSS" or "subscribe" to find the current feed link.

What the Tool Actually Does with Your Feed

Provide a valid public http or https RSS or Atom feed URL under the size limit, and the RSS to PDF tool fetches the feed and renders the most recent items into a PDF. For each item, the PDF includes the title, author, date, and a plain-text summary. HTML tags are stripped. The PDF does not reproduce the site's original layout, images, or styling. Expecting a visual copy of the website will disappoint you.

If your feed passes every check and still fails, test it with the W3C Feed Validation Service to rule out syntax issues. A valid, public feed works with rss2pdf.com.
