Why should I convert HTM to EPUB?

HTM is optimized for web browsers with fixed layouts and interactive scripts, while EPUB is a reflowable e-book format that adapts text to any device. Converting HTM to EPUB makes your content readable on e-readers, tablets, and phones, improves accessibility, and can reduce file size by compressing images and removing unnecessary code.

How does the conversion handle HTM scripts, images, and layout?

Our converter strips JavaScript and form elements that are unsupported in EPUB, while preserving text, headings, images, and CSS styles. Images are compressed and re-encoded to EPUB-compatible formats (JPEG, PNG, GIF). Layout is converted from fixed pixel dimensions to reflowable blocks, so your content flows naturally on different screen sizes.
