How to Convert Images to WebP
- 1Drop one or more images — JPG, PNG, GIF, and BMP are all accepted as input.

- 3Convert files process in your browser simultaneously. A progress indicator shows each file as it completes.
- 4Download converted WebP files individually or as a ZIP. Nothing is uploaded to any server.
When to Convert to WebP
Web Performance & Core Web Vitals
WebP is Google's recommended image format for the web. Smaller files mean faster LCP (Largest Contentful Paint) scores, which directly impact search rankings. Our guides on converting to WebP and image SEO cover the full impact.
CMS & E-Commerce Platforms
WordPress (6.1+), Shopify, and most modern platforms natively serve WebP. Pre-converting before upload gives you better control than relying on platform-side conversion, which varies in quality.
Replacing PNG with Transparency
WebP supports transparency like PNG but with significantly better compression. For transparent images on the web, WebP is almost always the right choice over PNG. See our format comparison guide.
Mobile & Data-Conscious Users
Smaller WebP files reduce data consumption for mobile visitors — a significant consideration for international audiences on metered data plans or slower networks.
Why Convert to WebP in the Browser
WebP conversion runs entirely in your browser via the Canvas API — your images are never uploaded. Browser support for WebP is now effectively universal (all modern browsers since 2020), so there's no longer a meaningful compatibility reason to stick with JPG or PNG for web use. For a complete web image optimization workflow: resize with our Image Resizer to your target display dimensions, then convert to WebP here. Batch convert your existing image library using this tool alongside our Bulk Compressor for maximum file size reduction across a site.
Frequently Asked Questions
WebP is a modern image format developed by Google, designed specifically for the web. It uses advanced compression to produce files that are typically 25–40% smaller than equivalent JPG or PNG files at the same visual quality. All major browsers now support WebP, making it the recommended format for web images. Smaller images mean faster page loads, lower bandwidth costs, and better SEO rankings.
At the same quality setting, WebP is visually indistinguishable from JPG or PNG while being significantly smaller. The default quality of 82 in our converter is a well-tested sweet spot — you get maximum file size reduction with no perceptible quality loss. Only if you set quality very low (below 60) will you start to see compression artifacts.
Yes — WebP supports full alpha channel transparency, just like PNG. This makes it an ideal replacement for PNG in web use, as you get the same transparency support with a much smaller file size. If your PNG has a transparent background, converting it to WebP will preserve that transparency.
While browsers support WebP, some older software — like certain versions of Photoshop, Microsoft Office, or email clients — may not. You might also receive WebP images from a website or developer and need to share them with someone whose tools don’t support the format. Converting back to JPG or PNG ensures universal compatibility.
Yes — WebP is supported by all modern browsers including Chrome, Firefox, Safari (since version 14), Edge, and Opera. Global browser support is now over 97%, making WebP safe to use for virtually all web projects. The only edge cases are very old browsers (Internet Explorer, Safari pre-2020), which are now a negligible fraction of web traffic.
