How to optimize HTML?

Open the site: HTML . Drag and drop HTML files to optimize and compress them online. Or just use a code sample in Java. Install Aspose.Words for Java. Add a library reference (import the library) to your Java project. Open the source HTML file in Java. Compress HTML without losing quality. Call the Document.cleanup() method. The resulting code may vary depending on the output file format. Get the compressed result as a HTML file.

Why compress HTML files in Java?

Compressing HTML allows you to improve the use of disk spaces and network traffic without sacrificing data quality.

What output file formats can I use to compress HTML files?

We support a variety of output file formats for HTML optimization, including DOCX, DOC, RTF, ODT, EPUB, JPG, PNG, XLS, XLSX, WPS and many more.
