User Guide

How to use this tool

WebP is the workhorse web format of the modern era: smaller than JPG at the same visual quality, and smaller than PNG while still supporting full transparency and animation. This converter transforms JPG, PNG and other images into optimized WebP files without ever uploading them.

How to use it

Drop one or more images onto the upload area. The tool decodes each image, redraws it into an off-screen canvas, and then re-encodes it with the browser built-in WebP encoder. A live preview shows both the source and the WebP output so you can compare them visually.

The quality slider controls how aggressively the WebP codec compresses. A value around 78–5% is a strong default for photography and generally produces WebP files 25–5% smaller than an equivalent-quality JPG. Click Download to save the .webp file.

  • Supports both photographic (lossy) and flat-color (near-lossless) images
  • Preserves alpha transparency from PNG sources
  • Typical bandwidth savings of 25–0% versus JPG/PNG
  • Perfect for Shopify, WordPress, Next.js and static sites

SEO and performance benefits

Serving images as WebP directly improves Core Web Vitals metrics such as Largest Contentful Paint (LCP) and Total Blocking Time (TBT). Google Search Console flags oversized JPG/PNG assets as performance issues — converting them to WebP is one of the highest-ROI SEO fixes you can perform.

For older browsers that do not support WebP, serve a JPG fallback using the HTML picture element or your CDN content-negotiation feature.

Frequently Asked Questions

Is WebP supported everywhere?

All modern browsers (Chrome, Firefox, Edge, Safari 14+) support WebP — over 97% of global users.

Should I use lossy or lossless?

Lossy for photos, lossless for screenshots/diagrams with text and sharp edges.

What is the difference between lossy and lossless WebP?

Lossy WebP uses compression that discards some data (like JPG), ideal for photographs. Lossless WebP preserves every pixel exactly, best for screenshots, logos, and graphics with text.

How much smaller is WebP compared to JPG?

WebP lossy images are typically 25–35% smaller than equivalent JPG files at the same SSIM quality index. Lossless WebP is about 26% smaller than PNG.

Do all browsers support WebP?

Chrome, Firefox, Edge, Safari 14+, Opera, and most mobile browsers support WebP. This covers over 97% of global users. Use a JPG/PNG fallback inside <picture> tags for older browsers.

Is this tool free to use?

Yes. This tool is completely free with no sign-up, no watermarks, and no daily limits. All processing runs locally in your browser.

Should I use WebP or AVIF?

AVIF is even smaller but slower to encode. WebP hits the sweet spot for most sites; use AVIF for hero images and cover art.
