About JPG → WebP
Why convert JPG to WebP?
WebP gives you the same perceived photo quality as JPG with significantly smaller files, which means faster page loads and lower bandwidth bills. Every modern browser (Chrome, Firefox, Safari, Edge) renders WebP natively. If your site still serves JPG to non-Retina viewports, switching to WebP is the easiest win for Core Web Vitals.
What's the right quality setting?
WebP quality 80–85 usually matches JPG quality 90 visually, while being ~30% smaller. For hero images keep 85+. For thumbnails and decorative photos, 70–75 still looks clean and saves more bytes. The quality slider in verto previews the trade-off in real time.
Are my JPGs uploaded anywhere?
No. verto is a static page. The JPG bytes are decoded with the browser's Canvas API, re-encoded as WebP, and offered back to you as a download. Nothing leaves the tab. Closing the tab erases every file.
What you're converting between
A short primer on both formats so the trade-offs are obvious before you hit Convert.
JPG
SourceJoint Photographic Experts Group · introduced 1992
JPG (also written JPEG) is the format every device, browser, printer and email client can open. It uses lossy DCT compression tuned for photographs, which means file sizes are small but every save introduces a small generational loss. JPG cannot store transparency and is not designed for animation or for graphics with hard edges — it shines on continuous-tone photos.
Strengths
- Universal browser, OS and app support
- Very small files for photographs at quality 80–90
- Decodes fast on every device
Trade-offs
- No transparency — alpha is filled with a solid color
- Lossy: re-saving the same JPG slowly degrades it
- Poor on flat graphics, text and sharp edges
WebP
TargetWebP · introduced 2010
WebP is a modern image format from Google designed to replace both JPG and PNG on the web. It supports lossy and lossless compression, an alpha channel, and even animation, while typically producing files 25–35% smaller than JPG at equivalent visual quality. Every up-to-date browser (Chrome, Firefox, Safari, Edge) renders WebP natively, which makes it the default win for Core Web Vitals and bandwidth bills.
Strengths
- 25–35% smaller than JPG at the same visual quality
- Supports transparency, unlike JPG
- Native support in every modern browser
Trade-offs
- Some older tools, print kiosks and email clients still reject it
- Lossy WebP can soften text and hard edges at low quality
- Slower to encode than JPG
