Frequently asked questions
How do I convert HTML to EPUB?+
Upload your HTML file (or drag it onto the box above), wait a few seconds while StandardsPDF converts it in your browser, then download the EPUB. There is nothing to install and no account required.
Is converting HTML to EPUB free?+
Yes. HTML to EPUB conversion is free on the StandardsPDF free tier – no watermark, no signup, and no credit card. A Pro tier lifts the file-size and daily limits if you need more.
Will the EPUB keep the quality of my HTML?+
StandardsPDF aims for the highest fidelity the EPUB format allows, so your document comes through looking as close to the original as possible. Some format-specific details may adapt where EPUB works differently to HTML.
Will chapters survive when I convert HTML to EPUB?+
Yes – converting HTML to EPUB carries across chapter breaks, the table of contents and reflowable text so the EPUB reads correctly on any device.
Do I need to install anything to convert HTML to EPUB?+
No. Converting HTML to EPUB runs entirely in the browser – no desktop software, no extensions and no account for the free tier.
What is the maximum HTML file size I can convert to EPUB?+
Up to 100 MB per HTML on the free tier and 2 GB on Pro. If your HTML is larger, split it first or upgrade for the higher limit.
