Fast, instant PNG to ICO conversion. No signup required. Just drop your .png file and get .ico in seconds.
Batch Settings
Some metadata may not survive
Your PNG file may contain tEXt, iTXt, ICC metadata. ICO has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
Color depth reduction: 48-bit → 32-bit
PNG stores up to 48 bits per channel, but ICO supports only 32 bits. You may notice banding in smooth gradients (like sky or skin tones) where subtle color transitions are lost.
