Frequently Asked Questions
Why convert JPG to WebP?
WebP images are typically 25–80% smaller than equivalent JPG files. Smaller images mean faster load times, better Core Web Vitals scores, and lower bandwidth costs.
Does converting JPG to WebP reduce image quality?
Only if you choose a low quality setting. At quality 80–90, WebP produces visually identical results to JPG at a much smaller file size.
Is WebP supported by all browsers?
Yes. WebP has been supported by all major browsers since 2020, including Safari 14+. It is safe to use on any modern website.
Why is my WebP file larger than the JPG?
If the source JPG was already aggressively compressed (typically below quality 60), re-encoding to WebP at quality 95 can produce a heavier file. Match the target quality to the source, or simply lower it, and the gain returns immediately.
Are EXIF data and the colour profile preserved?
EXIF metadata (camera, GPS, capture date) is removed by default for privacy. The sRGB colour profile is preserved so colours stay accurate on every screen. Use our metadata removal tool for finer control.
How do I serve WebP with a fallback for older clients?
Use the HTML <picture> element. Declare a <source type="image/webp"> first, then a <img src="…jpg"> fallback. Modern browsers load the WebP, older ones the JPG, with no JavaScript needed.
