PNG and WEBP

PNG is lossless and supports transparency, which makes it the usual choice for screenshots, logos and graphics with sharp edges.

WebP is Google’s web image format. It is usually 25–35% smaller than JPG at the same quality and supports transparency and animation.

In Settings you can choose the image quality (Maximum to Smallest) and whether to keep or strip metadata such as camera details and location.

Why convert on your computer?

Online converters upload your PNG files to someone else’s server, limit file sizes and often add queues or watermarks. nxtconvert does the work locally with the same engines professional tools use, so it’s private, works offline and handles large files and big batches.
