Convert based on end use

JPG is a practical choice for photos and compatibility. PNG retains transparency and tends to work well with graphics. WebP can deliver small files while maintaining good quality in modern environments.

Transparency when moving to JPG

JPG does not support transparency. If your PNG or WebP has transparent areas, turn on the white background to prevent those areas from appearing an unexpected color.

Frequently Asked Questions

Does renaming .webp to .jpg convert the file?

No. Changing the extension does not change the internal data. An actual conversion re-encodes the image into the output format.

Does PNG always have better quality?

Not necessarily. PNG and JPG are designed for different needs. The best choice depends on the type of image and whether you need transparency.
