How much smaller is WebP than JPG?
At matching visual quality, WebP files come out 25–35% smaller than their JPG sources — the result of a newer compression algorithm doing more with every byte. For a website, that is a direct Core Web Vitals win; for storage, it is a third of your photo folder back. Drag a JPG in and the live size comparison shows your exact saving before you download.
Where WebP is (and isn’t) accepted
Every modern browser, WordPress, and the major social platforms handle WebP natively, so for anything web-bound it is the safe default. The holdouts are older desktop software and the occasional conservative upload portal. Keep the original JPG until you have confirmed your destination accepts WebP — converting back is possible but re-encoding twice costs a little quality.
Picking the right WebP quality
The default of 80 matches typical JPG quality while capturing the full size saving, and suits almost every photo. Push to 90 for portfolio images where every detail counts; drop toward 65 for thumbnails and previews where speed beats fidelity. The preview updates live, so judge with your own eyes rather than the number.
Frequently asked questions
Will the WebP look worse than my JPG?
No — at the default setting it looks the same and is roughly a third smaller. WebP simply compresses more efficiently.
Do browsers support WebP?
All modern browsers have supported WebP for years. Only very old software may refuse it.
Can I convert back from WebP to JPG?
Yes, with our WebP converter — though each lossy re-encode discards a little detail, so keep originals when you can.
Is this private?
Fully. The conversion runs in your browser and your photos never leave your device.
