Convert OPF to JPG

Understanding OPF and JPG file formats

The OPF (Open Packaging Format) is a file format used primarily in eBook publishing. It is part of the EPUB standard and contains metadata, a manifest of all files in the eBook, and a spine that dictates the reading order. On the other hand, the JPG (or JPEG) format is a widely-used image format known for its lossy compression, making it ideal for storing and sharing photographs and images on the web.

Why convert OPF to JPG?

Converting an OPF file to a JPG format might be necessary if you want to extract images from an eBook for use in presentations, websites, or other visual media. Since OPF files are not directly viewable, converting them to a more accessible format like JPG can be beneficial.
