Format guidance
Why convert JPG to WebP?
WebP is useful for websites because it can store detailed photographs efficiently while retaining good visual quality. The improvement varies with the source image and encoder setting.
Current major browsers support WebP, but a legacy publishing system or older offline application may still prefer JPG. Keep the original when you need a fallback.

Frequently asked questions
Is WebP always smaller than JPG?
No. WebP is often efficient, but image content, the original JPG, browser encoder, and quality setting all affect the result.
Does the WebP keep the same dimensions?
Yes. Format conversion keeps the original width and height.
Can I control WebP quality?
Yes. The converter starts at 90% and lets you choose a lower or higher setting before processing.
Is my JPG sent to a server?
No. Conversion and preview generation take place locally in your browser.
