About HTML to OPML Conversion
Short answer: yes, you can convert HTML to OPML online for free, and quality is well preserved with the right settings. Just upload your .html file to CocoConvert, pick OPML as the output, and click Convert. The whole process takes seconds.
Now for the details. HTML (HyperText Markup Language) is the standard language for web pages. OPML is a widely used file format. Converting between these two formats lets you convert between formats quickly.
Your HTML file is decoded and re-encoded as OPML. Converting HTML to OPML maintains high quality with CocoConvert's optimised encoder settings.
CocoConvert runs entirely online — no software to install, no account to create. Your files are encrypted during upload (TLS), processed on isolated servers in Germany, and permanently deleted after 24 hours. It works in Chrome, Safari, Firefox, Edge, and all mobile browsers.
Need to convert more than one file? Free users can do 5 per hour. Pro gets 100 per hour with files up to 5 GB each.
