Frequently Asked Questions
How much smaller is WebP compared to JPG?
Google's benchmarks show WebP averages 25–34 % smaller file sizes than JPG at equivalent visual quality. Real-world savings vary by image content — photos with many colors and gradients typically see the best results from the more efficient codec.
Will my photos look worse after converting JPG to WebP?
At typical quality settings the visual difference is negligible. WebP's compression algorithm is simply more efficient than JPG's, so you get a meaningfully smaller file without introducing obvious artifacts or color shifts at equivalent quality levels.
Is WebP supported by all browsers?
WebP is supported by Chrome, Firefox, Safari (since version 14 in 2020), and Edge — covering over 95 % of global web users. Older iOS versions and Internet Explorer do not support it, so serving a JPG fallback covers those edge cases.
Should I switch my website from JPG to WebP?
For most web use cases, yes. WebP delivers the same visual quality at a smaller file size, speeding up page loads and improving Core Web Vitals. Pair it with a JPG fallback using the HTML picture element to cover older browsers.
Are my photos safe when I convert JPG to WebP on Image Machine?
Completely safe. The conversion runs inside your browser using local processing — your images are never uploaded to any server and remain entirely on your device throughout the process.
