WebP is a web format that is smaller than JPG and supports transparency and animation. Current browsers open WebP, but support in programs and services is uneven.
JPG is the most widely used lossy format for photos. When you convert WebP to JPG, you can open it in more places, a solid background replaces transparency and the file grows. See the comparison below for what changes.
This converter reads the file itself to confirm it is WebP, then converts it to JPG right in your browser. Your image is never uploaded.
WebP vs JPG: what's the difference?
| Item | WebP | JPG |
|---|---|---|
| Compression | Lossy or lossless | Lossy |
| Transparent background | Yes | No |
| Animation | Yes | No |
| Introduced | 2010 | 1992 |
| Support in programs and upload forms | moderate | nearly everywhere |
| Shown directly in browsers | Yes | Yes |
| Photo file size (JPG = 1) | about 0.7× | baseline (1×) |
What is WebP?
WebP is a web image format Google released in 2010. At the same quality it can be roughly 25-35% smaller than JPG, and it handles lossy and lossless compression, transparency and animation in a single format.
What is JPG?
JPG (JPEG) is a lossy format standardized in 1992. It drops information the human eye is less sensitive to, making photos very small. It is the format cameras and smartphones save by default, so it is the one you meet most often.
What changes when you convert WebP to JPG
Transparent areas are filled with the background color you choose
JPG can't represent transparency. Transparent and semi-transparent areas are composited onto the background color in the options (white by default), so pick a matching color first if the image will be used on a dark screen.
An already-compressed image is compressed again
Both WebP and JPG are lossy, so converting WebP to JPG adds a little more degradation. Keeping quality at 90 or higher usually avoids visible differences, and it's best to convert from the original only once.
Moving images keep only their first frame
JPG can't hold animation. If your WebP file is animated, only the first frame is converted.
You can adjust quality, size and background color
When converting WebP to JPG, you can use the quality slider (default 90), exact width-and-height sizing with margin fill, and percentage resizing. WebP is already lossy, so pushing quality too low stacks up visible degradation. Even when size matters, try not to go below 80.
How the file size changes
For the same photo, JPG tends to be larger than WebP (about 1.4×). This is for photos; for simple images such as logos and screenshots, PNG can actually come out smaller.
JPG opens in more places
Support for WebP in programs, document tools and upload forms is moderate, while JPG is nearly everywhere. If you need to upload somewhere WebP wouldn't open, try again after converting.
When to convert
- You need to upload to a program, messenger or upload form that can't open WebP
- You're submitting to a place that doesn't need transparency (print, certificates, a product's main image) with a white background
- You're preparing an image for typical JPG uses (sharing photos, blog and online-shop product photos)
WebP → JPG: practical tips
Most of the time, saving an image from a website with "Save image as" gives you a .webp file. The server sent WebP to your browser; the image itself is unchanged and only the extension is unfamiliar.
PowerPoint, word processors, older versions of Photoshop and some online-shop product forms reject WebP. Converting to JPG at a quality around 90 makes it open anywhere without a big difference in size.
If the WebP has a transparent background, JPG needs a background color. For a white-background product photo keep the default (white); for an image on a dark screen, pick black or the matching color.
