Lower quality results in a smaller file size but poorer image quality.
100 = lossless WebP: every pixel kept. Often the smallest choice for screenshots, logos and text.
When to Convert JPG to WebP
Convert JPG to WebP when you want to serve photographs on the web at even smaller file sizes than JPG can achieve. In Google's tests, WebP files were 25-34% smaller than JPGs of equal visual quality, making it the preferred format for performance-conscious websites. This conversion is particularly impactful for image-heavy pages like photo galleries, product listings, and travel blogs.
JPG vs WebP Comparison
| Feature | JPG | WebP |
|---|---|---|
| Compression | Lossy | Lossy or Lossless |
| Transparency | No | Yes (alpha channel) |
| Best For | Photos, web images | Web optimization |
| File Size | Small | Very Small |
| Browser Support | Universal | All modern browsers |
Quality & Compression
WebP uses a more advanced compression algorithm than JPG (based on VP8 video codec technology), which means it can represent the same visual quality with less data. At equivalent perceptual quality, WebP avoids the blocky artifacts that JPG produces at lower quality settings. However, since the source is already a lossy JPG, the conversion introduces a second generation of lossy encoding — a quality of 75-80 is where the WebP usually comes out smaller than the JPG it came from. The converter starts at 80.
File Size Differences
How much you save depends on how heavily the JPG was already compressed. In our tests, a camera-quality 356 KB JPG became a 171 KB WebP at quality 80 (51% smaller), while a web JPG that had already been compressed shrank by just 1% at the same setting — and grew by 42% at quality 90. The converter shows the size change before you download; if the WebP is bigger, lower the quality or keep the JPG.
Use Cases
E-commerce platforms are among the biggest beneficiaries of JPG-to-WebP conversion. A large online store might have 50,000+ product photos stored as JPGs. Converting these to WebP and serving them via a CDN with content negotiation (falling back to JPG for unsupported browsers) can reduce monthly bandwidth costs by thousands of dollars while improving the shopping experience through faster image loading.
News organizations and media websites that publish dozens of articles daily, each with multiple JPG photographs from wire services and staff photographers, gain compounding benefits from WebP conversion. With millions of daily page views, even a 30% reduction in image payload per page translates to significant infrastructure savings and faster time-to-interactive metrics across their entire audience.
Real estate listing sites and travel platforms are another strong use case. These sites feature large, high-quality photographs that drive user engagement — property walkthroughs with 30+ images per listing, or destination guides with panoramic shots. Converting from JPG to WebP keeps the visual impact intact while ensuring pages load quickly enough that prospective buyers and travelers do not bounce.
