Domande Frequenti

Convertire JPG in PNG migliora la qualità?

No. JPEG is lossy, so quality lost during original compression cannot be recovered. The PNG version will be lossless going forward but won't look better than the original.

Perché il file PNG è molto più grande?

PNG uses lossless compression which preserves all pixel data, resulting in larger files. JPEG achieves smaller sizes by discarding some image data.

Will the colors change after conversion?

Colors are preserved exactly. However, if the JPEG has color profile information, it may be interpreted differently by some viewers.

Is my file uploaded to your servers?

No. The conversion happens entirely in your browser using client-side JavaScript. Your files never leave your device.
