Questions Fréquentes

Why convert JPG to PNG?

PNG supports transparency and uses lossless compression, making it ideal for logos, icons, screenshots, and graphics that need sharp edges. JPG loses quality on each save; PNG preserves every pixel.

Will the file size increase?

Usually yes — PNG files are larger than JPG because PNG uses lossless compression. For photos, PNG can be 3-5x larger. For graphics with flat colors, the difference is smaller.

Will I get transparency from a JPG?

No — JPG has no transparency data. The converted PNG will have the same solid background as the original JPG. To add transparency, use an image editor after conversion.
