JPEG vs WebP
JPEG is widely supported for photographs, while WebP can use lossy or lossless compression and supports transparency. For web delivery, results depend on the source image, encoder settings, and target browsers.
Which format should you choose?
Use JPEG when broad compatibility is the priority; consider WebP when you can test target browsers and compare actual quality and size.
Good fit for JPEG
Photographs · Web images
- Photographs intended for compact sharing
- Images with many colors
Good fit for WebP
Web image delivery · Photographs · Transparent web assets
- Reducing web-image transfer size
- Assets that need transparency or animation
Basic information
| Field | JPEG | WebP |
|---|---|---|
| Extension | .jpg, .jpeg | .webp |
| MIME type | image/jpeg | image/webp |
| Common uses | Photographs · Web images | Web image delivery · Photographs · Transparent web assets |
| How to open | Most operating-system viewers, web browsers, and image editors can open JPEG files. | Open WebP files in a compatible browser, image viewer, or image editor. |
| Export or convert | Exporting JPEG to PNG or WebP cannot restore data already removed by JPEG compression. Keep an original editing file, and use a proper export command rather than changing only the filename extension. | When exporting WebP to JPEG, transparency is not retained and the output is lossy. When exporting to PNG, decide whether a still image is sufficient and handle animation separately if necessary. Before converting JPEG or PNG to WebP, choose lossy or lossless encoding and confirm transparency and animation requirements. |

Compare representative images at the intended display size and quality. Test browser support, transparency, and fallback behavior, and retain the original source for future exports.
- JPEG is a common choice for photographic images and exchange.
- WebP is designed for web delivery and supports both lossy and lossless encoding.
- Conversion may alter image quality, metadata, or color handling.
Frequently asked questions
Is WebP always better than JPEG?
No. Compatibility, image content, encoding settings, and the delivery pipeline affect the result.
