How to change image format
- Choose one still JPG, PNG or WebP image.
- Choose the output format. Pixel dimensions stay the same; camera orientation is applied.
- Convert, check the preview and file size, then download.
Which format should I choose?
JPG suits photos without transparency. PNG keeps transparency without adding lossy compression. WebP is useful for web images and supports transparency. WebP output requires a browser with a WebP encoder.
Does conversion make the file smaller?
Not always. The encoded file can be larger, especially when converting a photo to PNG. Check the actual size before downloading.
What happens to a transparent PNG?
Choose a format for the destination. PNG or WebP can keep a badge transparent; JPG needs an opaque background. Renaming .png to .jpg does not convert an image.


Select the original transparent PNG and choose JPG. The result stays 960 × 640, but transparent areas become white. The checkerboard behind the original is only a preview background.
Here JPG is smaller, but discards transparency and uses lossy encoding. Converting it back to PNG cannot restore transparency or lost detail. Compare the downloads at full size.

When should I keep PNG?
When transparency or sharp graphic edges matter. Photos often become larger in PNG. Choose JPG if the destination accepts it and transparency is unnecessary; check fine text afterward.
Why can this browser not save WebP?
WebP export needs a browser encoder. Some browsers can display WebP but cannot create it through this tool. After an encoder error, choose PNG or JPG, or another browser with WebP output support.
What a WebP becomes as JPG or PNG
We saved our 25 CC0 photos as WebP with this converter at quality 80. Then we converted each WebP the way you would here: to JPG at the default 92, to JPG at 80, and to PNG. Every output is bigger than the WebP.
WebP to JPG and PNG, by kind of photo

| Low light | 5 | 342.1 KB | 659.3 KB (2.1×) | 440.7 KB (1.4×) | 4.76 MB (16.0×) |
| Close-up textures | 4 | 1.27 MB | 2.34 MB (1.9×) | 1.48 MB (1.2×) | 14.04 MB (12.5×) |
| Food and products | 6 | 370.7 KB | 835.8 KB (2.6×) | 507.8 KB (1.5×) | 4.93 MB (20.1×) |

Brackets: times the size of the WebP. Close-up textures were already large as WebP, so they grew least.

Each output, all 25 photos
| Output | Bigger than the WebP | Times the WebP | Similarity to the WebP | Time (median) |
|---|---|---|---|---|
| JPG at 92 (default) | 25/25 | 1.6× to 3.4× | 0.994 (lowest 0.987) | 34 ms |
| JPG at 80 | 25/25 | 1.0× to 1.9× | 0.989 (lowest 0.969) | 32 ms |
| PNG | 25/25 | 9.7× to 25.9× | 1.000 (lowest 1.000) | 126 ms |
PNG keeps every pixel of the WebP, so it scores 1.000; the JPGs lose a little.

How to convert
- Add the WebP above. JPG is selected for you, because the file is not a JPG.
- Keep quality at 92, or lower it to 80 for a smaller file: in our test that gave 1.0× to 1.9× the size of the WebP instead of 1.6× to 3.4×.
- Press Convert image and check the size under the result.
- If a form also has a KB limit, put the JPG into the compressor.
- Download the JPG.
When WebP to JPG goes wrong
Why is the JPG bigger than the WebP?
WebP stores a photo more tightly than JPG. All 25 of our JPGs at 92 were bigger than their WebP, a median 2.3× its size. That is normal; check that the JPG fits your form's limit. The bigger-file guide has more cases.
Should I pick PNG instead?
Only if the form asks for PNG or you need transparency. Our PNGs were 9.7× to 25.9× the size of the WebP; the largest was 20.69 MB.
My transparent background turned white.
JPG has no transparency, so the converter fills it with white. Choose PNG to keep it.
The converter refuses my WebP.
Animated WebP files are refused with the message “Animated images are not supported. Choose a still image.” A file that is not really a WebP can be refused too; the WebP guide shows how to check.
