PNG

Not in standard PNG; APNG (Animated PNG) is a non-standard extension with limited, inconsistent support

Animazione

JPG

Not supported

PNG

24-bit RGB (16.7M colors) or 32-bit RGBA (16.7M colors + full alpha); up to 48-bit for professional workflows

Profondità colore

JPG

24-bit (8 bits per channel: RGB) — up to 16.7 million colors

PNG

100 KB – 10 MB — significantly larger than JPG for photographic content

Dimensione file

JPG

50 KB – 5 MB per image depending on resolution and quality setting

PNG

Universal — all modern browsers, operating systems, and devices including IE7+

Supporto browser

PNG in JPG: Quello che devi sapere

Il PNG è un formato senza perdita ideale per la grafica, ma produce file grandi che rallentano siti web e applicazioni. La conversione da PNG a JPG applica una compressione intelligente che riduce le dimensioni del file del 60–80% con una perdita di qualità percepibile minima sui contenuti fotografici.

Perché convertire PNG in JPG?

⚡

Siti web più veloci

I file JPG si caricano significativamente più velocemente del PNG per le fotografie, migliorando i punteggi di prestazione del sito.

Efficienza di archiviazione

Una foto PNG da 5 MB potrebbe comprimersi a 500 KB come JPG, risparmiando il 90% dello spazio di archiviazione.

💾

📷

Standard fotografico

Le fotocamere DSLR, i siti di stock photo e i servizi fotografici usano tutti il JPG come formato di distribuzione principale.

Compatibilità di stampa

I laboratori fotografici e i servizi di stampa on-demand accettano universalmente il JPG per tutti i lavori di stampa.
