Next step
Carry this file straight into another tool. It stays in your browser.
Counted with the browser's own PerformanceObserver, from the moment this page finished loading. Every request is counted, including this site's analytics — a counter that ignored some requests would not be worth reading.
Check it yourself: open DevTools (F12 or ⌘⌥I), pick the Network tab, tick Preserve log, then use the tool. Your file will not appear as an upload. Filter by Fetch/XHR to see requests the page made rather than assets it loaded.
Frequently Asked Questions
Will WebP always be smaller than JPG?
No. Content, source compression, dimensions, and the selected quality all influence the result.
Does converting make the page faster automatically?
A smaller file can reduce transfer time, but the site must serve the WebP correctly and use appropriate dimensions, caching, and loading behavior.
Should I delete the JPG?
Usually not. Keep a broadly compatible source or master and use WebP as a delivery copy where supported.
Does JPG become transparent in WebP?
No. The input has no alpha channel, so the output remains opaque.
Does this resize the photo?
No. Use Image Resizer if the delivered pixel dimensions are also larger than needed.
