Format notes
When to use this output
Use JPG to WebP when you control a website or app bundle and want smaller hero images without running a server-side pipeline. WebP is supported in all major browsers for still photos.
Transparency
A standard JPG has no alpha channel, so the WebP output is opaque. For transparent art, start from PNG and use PNG to WebP instead.
Quality
WebP lossy modes can match JPG visually at lower bitrates. Tune the Quality slider; compare the preview before you download.
File size
WebP is typically 25 to 35 percent smaller than JPG at similar perceived quality for photographs. Simple graphics may see smaller gains.
FAQ
Can I email WebP?
Some mail clients still prefer JPG attachments. Convert to WebP for web hosting, JPG for conservative email recipients.
Will old Safari open it?
Modern Safari decodes WebP. Very old iOS versions may not; keep JPG as a fallback audience.
Is this the same as AVIF?
No. This tool outputs WebP only. AVIF has a separate converter pair on this site.
