ToolBox Image — PNG बनाम WebP बनाम AVIF — कौन सा फ़ॉर्मेट सबसे अधिक जगह बचाता है?

हम वास्तविक इमेज — तस्वीरें, स्क्रीनशॉट, लोगो और ग्राफ़िक्स — पर PNG, WebP और AVIF कंप्रेशन की तुलना करते हैं ताकि देख सकें कि फ़ाइल आकार, गुणवत्ता और संगतता के मामले में कौन सा फ़ॉर्मेट जीतता है।

If you regularly save images for the web, you have noticed that file sizes vary wildly between formats. A PNG that looks identical to a WebP can be three times as large. An AVIF can be half the size of a JPEG at the same quality.
