Convert JPG to WEBP online
Convert JPG to WebP to serve the same photograph at a meaningfully smaller size. At quality 90 with maximum compression effort, WebP typically lands 25–35% below the JPG while looking the same at normal viewing sizes.
When should you convert JPG to WEBP?
- Reduce page weight on an image-heavy website
- Cut bandwidth costs on a photo gallery or a product catalogue
- Improve load times without visibly degrading the images
- Modernise an asset pipeline that is still shipping only JPG
Before you convert
A second lossy pass
Both formats are lossy, so the WebP is encoded from an already-compressed JPG. The size gain is real; the quality does not improve. Encode from the original if you have it.
Keep a JPG fallback for emails
WebP works in every current browser but is still rejected by some email clients and older upload forms.
What happens to your file
WebP is encoded at quality 90 with compression method 6, the slowest and most thorough setting, which is why WebP output is typically smaller than the JPG or PNG it came from at comparable quality.
Settings this conversion runs with
| Engine | Pillow (Python Imaging Library) |
|---|---|
| Quality | 90 by default |
| Effort | method 6 — highest compression effort |
What changes
- Nothing in the picture is resampled unless you ask for it — resize, crop-to-aspect, and background removal are opt-in, so a plain JPG to WEBP keeps the original pixel dimensions.
