Why switch from JPG to WebP?
WebP was developed by Google specifically to improve web image performance. Switching to WebP is one of the simplest optimizations you can make to speed up a website:
- Smaller files — 25–35% smaller than JPEG at equivalent visual quality.
- Faster page loads — Smaller images transfer faster, improving Core Web Vitals (LCP).
- Universal support — Supported in all modern browsers since 2019.
- Transparency support — Unlike JPG, WebP supports alpha transparency.
Frequently asked questions
How much smaller will my images be after converting to WebP?
Typically 25–35% smaller than the equivalent JPG at the same visual quality. Google's benchmarks show WebP achieving 34% smaller file sizes than JPEG. Results vary by image content — photos with complex textures see the biggest gains.
Is WebP supported by all browsers?
Yes. WebP is supported in Chrome, Firefox, Safari (since 14), Edge, and Opera — effectively all modern browsers. Over 97% of global browser usage supports WebP as of 2025.
Will converting JPG to WebP visually degrade my images?
At quality settings of 80 or above, the difference between WebP and JPG is imperceptible on screen. WebP achieves better compression at the same perceptual quality level, so a WebP at quality 80 typically looks the same as a JPG at quality 90.
Can I convert JPG to WebP without uploading my files?
Yes. The 365tools Image Converter processes files entirely in your browser using the Canvas API. Your JPG files are never sent to any server.
Does WebP support transparency?
Yes — unlike JPG. WebP supports full alpha-channel transparency, just like PNG. This makes it a better choice than JPG for images that need transparent backgrounds.
