How is a JPEG image converted to WebP?

The conversion runs on PicPerf's image processing service: your JPEG is decoded and re-encoded as WebP using high-quality compression settings. The file is processed for the conversion only and never stored.

Will I lose image quality converting JPEG to WebP?

WebP supports both lossy and lossless encoding. This tool encodes with the highest quality settings, so the WebP result is usually visually indistinguishable from the original JPEG while taking up less space. Photos are where the format shines; JPEG's own lossy artifacts aren't added to.

How much smaller is WebP than JPEG?

Savings depend on the image, but WebP is typically 25–35% smaller than an equivalent-quality JPEG, with the biggest gains on photographic content. Over a page full of images, that difference adds up fast.

Is WebP supported everywhere?

All modern browsers — Chrome, Edge, Firefox, and Safari — support WebP. If you need to support very old browsers or specific offline tools that predate WebP, keep a JPEG or PNG fallback.

Does WebP support transparency?

Yes. Unlike JPEG, WebP supports alpha transparency and animation. A JPEG has no transparency to carry over, but if you convert a PNG to WebP instead, transparency is preserved.
