FAQ
How much smaller is WebP?
At comparable perceived quality, WebP is typically 25–35% smaller than JPG. The actual result depends on content and quality setting — the page shows the real change per file, so you can judge whether the swap is worth it.
Do all browsers support WebP?
Yes. Chrome, Edge, Firefox, Safari 14+, and the major mobile browsers all support WebP, covering over 95% of users. The caveat is outside the browser: some older desktop software and upload forms still do not read it, so be careful with images users will download.
What should I watch for when switching a site to WebP?
Use the HTML picture element to offer both WebP and the original format so unsupported clients fall back automatically. Also, converting an already-compressed JPG means a second lossy pass — keep quality at 70 or above.
Converting to WebP is about page weight
The core reason to convert JPG to WebP is loading speed. At comparable perceived quality, WebP is typically 25–35% smaller than JPG, and the more images a page carries, the more that saving adds up — directly in your PageSpeed score and in how long visitors wait. If you are optimising your own site, blog, or product pages, batch-converting JPGs to WebP is a high-value step. The page shows the real before-and-after size for each file, so you can judge which images are worth replacing.
Compatibility and how to swap
Chrome, Edge, Firefox, Safari 14+, and the major mobile browsers all support WebP now, covering over 95% of users, so the web case is safe. The real caution is outside the browser — some older desktop software and upload forms still do not read WebP, so be careful with images users download. On a site, use the HTML picture element to offer both WebP and the original so unsupported clients fall back to JPG automatically. And since converting an already-compressed JPG is a second lossy pass, keep quality at 70 or above to avoid stacking visible loss.
