About Image to WebP
Image to WebP re-encodes JPG and PNG images into WebP, Google's image format designed for the web. At a comparable quality setting WebP files are typically 25–35% smaller than the equivalent JPG and much smaller than PNG, because its compression is more efficient. A quality slider lets you trade a little detail for a smaller file. WebP is supported by every current browser, so the smaller files load faster without a fallback in most cases.
How to use this tool
- Upload an image.
- Choose the output quality.
- Convert to WebP.
- Download the WebP file.
Examples
photo.jpg · 1.8 MB · 3000×2000
photo.webp · ~700 KB · 3000×2000 (quality 80)
Same dimensions and near-identical appearance, roughly 60% fewer bytes at quality 80.
Tips & gotchas
- Use the quality slider to balance size and sharpness — around 75–85 is usually indistinguishable from the original for photos.
- WebP is supported in all modern browsers, so you rarely need a JPG fallback for current visitors.
- WebP supports transparency, so converting a transparent PNG keeps its alpha channel (unlike converting to JPG).
- Lower quality settings introduce more compression artifacts in flat color and text areas; bump the slider up for screenshots and logos.

Frequently asked questions
How much smaller will the WebP be?+
At a similar quality setting WebP is usually 25–35% smaller than JPG and considerably smaller than PNG. The exact saving depends on the image and the quality you choose.
Is WebP supported everywhere?+
Yes. Every current browser — Chrome, Firefox, Safari, and Edge — displays WebP, so it is safe to use on the web today.
Does converting to WebP keep transparency?+
Yes. Unlike JPG, WebP supports an alpha channel, so a transparent PNG keeps its transparency when converted.
Will I lose image quality?+
WebP here uses lossy compression, so very low quality settings can show artifacts. Keep the slider around 75–85 for photos and higher for text or line art to keep the result visually clean.
