Frequently Asked Questions

What is WebP format?▼

WebP is a modern image format developed by Google that provides superior lossless and lossy compression. It supports transparency (like PNG) and animation (like GIF) while producing significantly smaller file sizes.

Is WebP better than JPEG?▼

Yes. WebP lossy compression produces 25-35% smaller files than JPEG at the same visual quality. This means faster page loads, less bandwidth usage, and better user experience — all while maintaining comparable image quality.

Are my images uploaded to a server?▼

No. All conversion happens entirely in your browser using the HTML5 Canvas API. Your images never leave your device. This makes the tool 100% private and secure — no uploads, no servers, no tracking.

Is there a file size or quantity limit?▼

No limits. You can convert as many images as you want, of any size. The only constraint is your browser's available memory. For very large images (4000+ pixels), processing may take a few seconds per image.

Which browsers support WebP?▼

WebP is supported in Chrome (since 2011), Firefox (since 2019), Safari (since 2020), Edge (since 2018), Opera, and Samsung Internet — covering over 97% of global browser usage. Our converter works in any modern browser.

Does WebP support transparency?▼

Yes. Lossless WebP supports an 8-bit alpha channel (256 levels of transparency), making it a great replacement for PNG. Our converter preserves transparency when converting PNG and GIF images to WebP.

How do I use WebP images on my website?▼

Use the <picture> element with a fallback: <picture><source srcset="image.webp" type="image/webp"><img src="image.jpg" alt=""></picture>. This serves WebP to browsers that support it and falls back to JPEG/PNG for older browsers.
