What is WebP? Why Convert?
WebP is a modern image format developed by Google that uses advanced compression algorithms to produce significantly smaller files than JPEG or PNG — without any perceptible loss in visual quality. A typical photo compressed to WebP will be 25–35% smaller than the same photo in JPEG format.
Google Search, Core Web Vitals, and PageSpeed Insights actively reward websites that use WebP. For website owners, e-commerce stores, and bloggers, converting product images and hero banners to WebP can dramatically improve page load speed, leading to better SEO rankings and higher conversion rates.

Frequently Asked Questions
Q: Will all browsers display my WebP images?
A: Yes. WebP is supported by 97%+ of modern browsers including Chrome, Firefox, Safari (14+), Edge, and Opera. For the rare exception, you can serve JPEG as a fallback using the <picture> element in HTML.
Q: Does converting to WebP lose quality?
A: Our tool uses a high-quality WebP encoding setting by default, so the visual difference between the original JPEG and the resulting WebP is imperceptible to the human eye, while the file size drops by 25-35%.
Q: Is my image safe? Does it get uploaded?
A: Your image is never uploaded to any server. The entire JPG to WebP conversion happens locally in your browser using the HTML5 Canvas API. When you close the tab, the image is gone from memory permanently.
Q: Can I convert PNG to WebP too?
A: Yes. PNG transparency (alpha channel) is fully preserved when converting to WebP, since WebP also supports transparency. You'll get a smaller WebP file that retains the transparent background.
