This online image converter provides a seamless way to transform your images while maintaining quality.

When to Use JPG vs PNG Format
Understanding when to use each format is crucial for optimal results:

The Problem with Quality Loss in JPG
JPG compression causes quality loss that accumulates with each save. This “generation loss” can severely degrade image quality over time. Converting to PNG using our JPG to PNG converter stops this degradation and preserves your image quality permanently. Many online converters further compress images during conversion, but our tool ensures lossless conversion that maintains original quality.
