About this tool
Use JPG for photographs, PNG when lossless quality or transparency matters, and WebP for efficient modern web images.
How to use it
- Select a JPG, PNG or WebP image.
- Choose the target format and quality.
- Convert and download the new image.
Choosing an image format
JPG is efficient for photographs but has no transparency. PNG is lossless and supports transparency. WebP usually offers good quality at smaller web file sizes.
Worked example
Example: Convert a transparent PNG logo to WebP to keep transparency while reducing the file size for a website.
Good to know
Converting a transparent image to JPG fills transparent areas with white because JPG does not support transparency.
