How to use

Convert images in 3 steps

No signup, no upload to any server, nothing to install. Drop your images in, tweak the quality, and download. Conversion happens entirely inside your browser tab.

Step 1

Add your images

Drag & drop PNG or JPEG files onto the upload area, or click to browse. Up to 20 images at a time, 25 MB each. PNG and JPEG can be mixed in the same batch.

Step 2

Pick a quality level

The default 80% is the sweet spot for the web, sharp images at a fraction of the original size. Slide down for even smaller files or up to preserve detail in product shots and graphics.

Step 3

Download & go

Each image shows its before/after size and savings. Download individual WebP files or grab everything in a single ZIP. Your files never leave your browser.

Why use it

Why WebP, why this tool

WebP is Google's modern image format and typically cuts file sizes 25–35% smaller than JPEG and PNG at the same visual quality, with full support across every modern browser.

100% private

Images never touch a server. Conversion happens locally in your browser using the native Canvas API, so you can safely convert client work, design exports, and screenshots.

Bulk conversion

Process up to 20 images in one pass. PNG and JPEG can be mixed freely. Each file gets its own row showing the source format, original size, new WebP size, and exact savings.

Download as ZIP

One click on "Download All" bundles every converted WebP into a single ZIP file, ready to upload to your CMS, hand off to a developer, or drop into your assets folder.

Adjustable quality

Slide between 40% and 95% to balance file size against visual fidelity. 80% is the typical sweet spot for the web, where WebP looks indistinguishable from the original to most eyes.

Faster page loads

Smaller images mean faster pages, better Core Web Vitals, and lower bounce rates. WebP is one of the easiest single optimizations for improving Lighthouse and PageSpeed scores.

Works on any device

Fully responsive, convert from your phone's gallery or your laptop. The WebP format itself is supported in Chrome, Safari, Firefox, Edge, and every modern mobile browser.

Who it's for

Built for the modern web

WebP is the format of choice when page speed matters, on a portfolio, an online store, a blog, a SaaS landing page. These are the people who reach for it most often.

Web Developers

Convert hero images, blog graphics, and component assets to WebP before they hit your build pipeline. Smaller files mean better Lighthouse scores and faster Core Web Vitals out of the box.

E-commerce Sellers

Shopify, WooCommerce, and BigCommerce all support WebP, and most theme images are still served as PNG or JPEG. Convert your product catalog once and watch mobile load times drop noticeably.

Bloggers & Publishers

WordPress, Ghost, and most modern CMSes accept WebP directly in the editor. Convert hero shots and inline images to dramatically reduce page weight without touching plugins or settings.

Designers

Export PNG or JPEG from Figma, Sketch, or Photoshop, then run a quick WebP pass before handing assets to engineering. Keeps file libraries lean and downloads instant for the dev team.

SEO Specialists

Page speed is a ranking factor, and image weight is usually the biggest culprit. Converting to WebP is one of the highest-leverage one-time fixes for moving Lighthouse and PageSpeed scores.

Marketers & Agencies

Landing pages with WebP hero images convert better, partly because they load faster and feel snappier. Quick wins for ad LPs, microsites, and any campaign where speed influences bounce rate.
