About formats

WebP is an image format developed by Google, announced on September 30, 2010, designed to provide superior compression for web images in both lossy and lossless modes. The lossy mode is derived from the VP8 video codec's intra-frame coding (the same technology used in WebM video), applying block prediction, transform coding, and adaptive quantization to photographic content. The lossless mode uses a distinct algorithm combining predictive coding, color space transforms, backward reference to repeated pixel patterns, and entropy coding. WebP also supports alpha transparency in both modes — lossy WebP with transparency is unique among common web formats, offering semi-transparent images at much smaller sizes than PNG. The format supports animated sequences as well, providing a modern alternative to GIF with full-color support and dramatically better compression. One advantage is substantial file size reduction — lossy WebP produces images 25-35% smaller than JPEG at equivalent visual quality, and lossless WebP is typically 26% smaller than PNG, directly improving web page loading speed and reducing bandwidth costs. Universal browser support provides another key strength: Chrome, Firefox, Safari, Edge, and all mobile browsers now render WebP natively, achieving the broad adoption threshold needed for practical deployment. Google's core web infrastructure (Search, YouTube thumbnails, Gmail) uses WebP extensively, and the format is supported by major CDN platforms, CMS systems, and image processing services. WebP has established itself as the primary modern alternative to JPEG and PNG for web content.
Developer: Google
Initial release: September 30, 2010
EPUB (Electronic Publication) is an open ebook standard originally developed by the International Digital Publishing Forum (IDPF) and now maintained by the W3C following the organizations' merger in 2017. The first version carrying the EPUB name was approved in October 2007 as a successor to the Open eBook Publication Structure (OEBPS). An EPUB file is essentially a ZIP archive containing XHTML or HTML5 content documents, CSS stylesheets, images, fonts, and metadata organized according to the Open Packaging Format and Open Container Format specifications. The current major version, EPUB 3, supports reflowable and fixed-layout content, embedded multimedia, JavaScript interactivity, MathML equations, and rich accessibility features including semantic markup and media overlays for synchronized text and audio. A defining advantage is universal device support — unlike proprietary formats, EPUB works natively on virtually every non-Kindle e-reader, tablet, and reading application, from Apple Books and Google Play Books to Kobo and dozens of third-party apps. The reflowable text model is another core strength, automatically adapting pagination, font size, and margins to match any screen dimension and user preference. EPUB's open specification and active W3C stewardship ensure long-term preservation and vendor independence, making it the de facto standard for digital publishing across libraries, academic institutions, and commercial retailers worldwide.

Frequently Asked Questions

Why convert WEBP to EPUB?

EPUB is the universal e-book standard — wrapping your WebP images in EPUB makes them readable on Kindle apps, Kobo, Apple Books, and more.

What devices read EPUB files?

Kobo e-readers, Apple Books on iPad/iPhone, Google Play Books, Calibre on desktop, and most third-party reading apps.

Can I include multiple images in one EPUB?

Upload multiple WEBP files to create a multi-page EPUB — each image becomes a page in your digital book.

Is EPUB good for image-heavy content?

EPUB supports embedded images well, though for pure photo books, fixed-layout EPUB works better than reflowable text layout.

Can I add text to the EPUB later?

Yes — EPUB is an open format. Use Calibre or Sigil to edit the EPUB and add text, metadata, or table of contents.
