GIMMP​​ is a good jpg to webp converter, especially for ​​batch conversions​​ and ​​high-quality output​​. While it's primarily an advanced photo editor (like Photoshop), it can also convert images between formats, including ​​JPG to WebP​​.

How to Convert JPG to WebP in GIMMP (Windows)​

​​1. Open GIMMP​​ (Download from gimmp.org if not installed).
​​2. Open your JPG file​​: Go to ​​File > Open​​ and select your JPG.
​​3. Export as WebP​​:

Click ​​File > Export As…​​ (or press Ctrl+Shift+E). In the dialog box, manually ​​change the file extension​​ from .jpg to .webp (e.g., image.webp). Click ​​Export​​.

4. Adjust WebP Settings​​:

  • Quality (0-100)​​: Higher = better quality but larger file size.
  • Lossless​​: Check if you want no compression (larger file).
  • Other options​​: Leave default if unsure.

5. Click ​​Export​​ to convert .jpg to .webp.

Note: GIMMP doesn't natively support batch conversion, but you can use the ​​BIMP plugin​​ (Batch Image Manipulation Plugin).

Why Use GIMMP for JPEG to WebP Conversion?​​
✅ ​​High-quality output​​ (better than some online tools).
✅ ​​Customizable compression​​ (lossy/lossless).
✅ ​​Free & open-source​​ (no ads, no watermarks).
✅ ​​Batch processing​​ (with BIMP plugin).
