Format Converter
Convert between PNG, JPG, and WebP formats.
Convert images between PNG, JPG, and WebP. The converter respects transparency where supported, lets you set output quality for lossy formats, and works in your browser with zero uploads.
How to use the Format Converter
- 1
Add your images
Drop one or many images onto the converter. Source files can be any common web format your browser can decode.
- 2
Pick an output format
Choose PNG for transparency and lossless quality, JPG for the smallest files when transparency is not needed, or WebP for the best size-to-quality trade-off on modern browsers.
- 3
Set the quality (lossy formats)
For JPG and WebP, set the quality between 1 and 100. PNG ignores this setting because it is lossless.

Frequently asked questions
Should I use WebP or JPG?
WebP produces 25–35% smaller files than JPG at the same visual quality, and every modern browser supports it. Choose JPG only if you need compatibility with very old software or systems that explicitly reject WebP.
What happens to a PNG's transparent background when I convert to JPG?
JPG does not support transparency, so transparent pixels are flattened against a solid white background. If you need to keep transparency, use WebP or stick with PNG.
Does WebP support animation?
WebP supports animation, but this converter outputs single-frame WebP only. For animated WebP or APNG, you will need a dedicated animation tool.
