Modern Format

WEBP is the next-generation web image standard — superior compression with excellent quality for captured web page content.

Convert by URL

Paste any web address and get an optimized WEBP screenshot — no need to save or download the page yourself first.

Tiny Output Size

WEBP images are dramatically smaller than equivalent JPG or PNG captures, loading faster on pages and in messages.

About formats

HTML (HyperText Markup Language) is the standard markup language for creating web pages, originally conceived by Tim Berners-Lee at CERN in 1991 and later standardized by the W3C and WHATWG. HTML structures content using a system of nested tags that define headings, paragraphs, lists, links, images, tables, forms, and multimedia elements, with CSS handling visual presentation and JavaScript adding interactivity. The language has evolved through major versions — HTML 2.0 (1995), HTML 4.01 (1999), XHTML 1.0 (2000), and the current HTML Living Standard (evolved from HTML5, published 2014) — each expanding semantic vocabulary and capabilities. HTML documents are plain text files interpretable by any web browser, and the language's role extends beyond websites: email formatting, ebook content (EPUB), application interfaces (Electron, Cordova), and document export all rely on HTML. One advantage is universal rendering — every computing device with a browser displays HTML content, making it the most widely supported document format in existence. The semantic markup model provides another strength: elements like <article>, <nav>, <aside>, and <figure> carry meaning that benefits accessibility tools, search engine indexing, and content reuse. The open, W3C/WHATWG-governed specification ensures vendor independence, and HTML's text-based nature means documents are trivially created, inspected, and processed with any programming language.

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.

Frequently Asked Questions

Why save a web page as a WEBP image?

WEBP delivers excellent image quality at significantly smaller sizes than JPG or PNG — ideal for web publishing and sharing.

Can I convert a URL directly to WEBP?

Yes — paste any public web address into Convertio and the service renders the page and delivers it as a WEBP image.

What opens WEBP images?

Chrome, Firefox, Edge, Safari, and most modern image viewers support WEBP natively. Older tools may need a plugin.

Is WEBP better than JPG for page captures?

WEBP typically achieves 25-35% smaller outputs at equivalent visual quality, making it superior for web-based content.

Does WEBP support transparency?

Yes — WEBP supports both lossy and lossless compression with full alpha transparency, unlike JPG which cannot.

Is the web page to WEBP converter free?

Yes — free for standard conversions on Convertio. Premium plans unlock batch processing and higher resolution outputs.
