Why convert OPF to WebP?
An OPF file is the package document inside every EPUB ebook, describing the book's metadata and listing the files it contains. The image shows the book title as a heading, a table of its creator, language and identifier, and a numbered list of the files in the package manifest.
WebP stores the rendered image in a modern, efficient format, so the file is noticeably smaller than an equivalent PNG or JPG.
Frequently Asked Questions
How do I convert OPF to WebP?
Drop your OPF file above and press Convert. Our servers read the package document, lay out its metadata and file list, and render the page. The result is saved as a compact WebP image, ready to download.
Which book details from the OPF file are shown in the WebP?
The title appears as a heading, followed by a table of the creators, language and identifiers recorded in the package metadata.
Does the WebP list the files named in the OPF manifest?
Yes. Every file referenced in the package manifest is shown in a numbered “Package files” list, giving a clear picture of the book's structure.
What happens when a OPF file fills several WebP pages?
Each page is rendered at 144 dpi and saved as its own WebP image, named page-1, page-2 and so on, and they download together as one ZIP. A single page downloads as one WebP file.
How much smaller is the WebP from a OPF file?
WebP typically produces files around a quarter to a third smaller than JPG at similar visual quality, and far smaller than PNG, while text and lines stay clear.
Is my .opf file kept private?
Your file is uploaded over an encrypted connection, converted on our servers and deleted automatically within 24 hours. We never read, share or keep your files, and no account is needed.
