Compare URLs Online

Enter the addresses of two web pages or online files to see what changed. For web pages, DiffNow compares the HTML source of the pages, with syntax highlighting. For links to documents such as Word or PDF files, it compares their text.

How to use it

  1. Enter the first URL and the second URL.
  2. Click Compare to see both pages side by side with the differences highlighted.
  3. Use Save/Share to send a link to the comparison, or Download to save it as an HTML report.

Questions

What can I use it for?

For example, to compare a staging site with the live one, two versions of a page, or two documents published online, without downloading them first.

Is there a size limit?

The first 2 MB of each page or file is compared; DiffNow Premium raises the limit to 8 MB.

Why can't DiffNow open my URL?

The page must be publicly accessible from the internet. Pages on a local network or behind a sign-in can't be fetched; save them as files and use the Files tab instead.
