Convert JPG to WebP — Free Online Image Converter

Convert JPEG images to WebP format to significantly reduce file sizes while maintaining visual quality. WebP uses advanced compression techniques that typically produce files 25–50% smaller than the equivalent JPEG at the same perceived quality, making it the preferred format for web images.

How to convert JPG to WebP

  1. Upload your JPEG file from your device, or paste a direct URL to fetch the image.
  2. Set the quality factor (0–100). The default of 95 preserves nearly all detail while reducing file size.
  3. Click "Convert to WebP!" and download the result.

Why convert JPG to WebP?

  • Smaller file sizes — at equivalent visual quality, WebP files are typically 25–50% smaller than JPEG. This directly improves page load times and reduces bandwidth costs.
  • Better compression — WebP uses more advanced prediction and entropy coding than JPEG, producing fewer artifacts at any given file size.
  • Improved web performance — smaller images improve Core Web Vitals (especially LCP), which Google uses as a ranking factor.
  • Transparency support — unlike JPEG, WebP supports alpha transparency. If your source image doesn't have transparency, this is not relevant, but it's a useful feature of the format.
  • Full browser support — all modern browsers (Chrome, Firefox, Safari, Edge, Opera) support WebP.

Understanding the quality setting

Since both JPEG and WebP are lossy formats, the quality factor controls how much compression is applied. Converting a JPEG to WebP is a lossy-to-lossy transcoding, which means some additional quality loss is inherent. To minimize this:

  • 90–100 — minimal additional quality loss. Use for images where visual fidelity is important (product photos, portfolio images).
  • 75–89 — good balance between size and quality. Suitable for most website images and blog illustrations.
  • 50–74 — aggressive compression. Useful for thumbnails, preview images, or when bandwidth is the primary concern.

Tip: If you have access to the original uncompressed source (PNG or TIFF), converting from that instead of JPEG will produce better WebP results, since you avoid the double compression. Use our PNG to WebP converter for that workflow.

Convert in the other direction: WebP to JPG. For other formats, see PNG to WebP and WebP to PNG.

Frequently asked questions

Is WebP better than JPEG?

For web use, yes. WebP produces smaller files at equivalent visual quality, which means faster page loads and lower bandwidth usage. However, JPEG remains more universally supported in older image editors and some specialized workflows (printing, CMYK color spaces). For web publishing, WebP is the better choice.

Does converting JPG to WebP lose quality?

Since both are lossy formats, converting from JPEG to WebP involves a re-encoding step that can introduce minor additional artifacts. At high quality settings (90+), this is imperceptible in practice. For best results, convert from the original uncompressed source if available.

Will the file size always be smaller?

In the vast majority of cases, yes. WebP produces smaller files than JPEG at any quality level. The savings are typically 25–50%, though exact results depend on image content and the quality setting used.

Can I convert WebP back to JPG?

Yes, use our WebP to JPG converter. Note that each lossy conversion introduces some quality loss, so avoid converting back and forth repeatedly.
