Why convert ICNS to PNG?
ICNS is Apple's icon container for macOS apps, folders and documents, bundling the same icon at several sizes from 16 up to 1024 pixels. The converter picks the largest icon stored in the file, including Retina @2x versions, and renders that single image at its native size.
PNG keeps every pixel exactly as rendered, so text, thin lines and flat colours stay crisp, and transparency is preserved.
Frequently Asked Questions
How do I convert ICNS to PNG?
Drop your ICNS file above and press Convert. Our servers read every icon element in the ICNS file, decode the largest one to PNG, then encode it in the format you chose. The result is saved as a lossless PNG, ready to download.
Which icon size from the ICNS set is used for the PNG?
The largest one in the file. A modern ICNS usually holds a 1024 × 1024 Retina icon, and that is the image the PNG is made from.
Can classic ICNS icons without PNG data become a PNG?
Yes. Alongside PNG and JPEG 2000 icon elements, the decoder reads the classic packed RGB icons at 16, 32, 48 and 128 pixels together with their 8-bit transparency masks.
How big is the PNG image from a ICNS file?
The largest image stored in the icon set is used, so the PNG is as detailed as the icon allows.
Why is PNG a good fit for a ICNS conversion?
PNG is lossless: the image keeps every rendered pixel with no compression artefacts, which keeps small text, table lines and drawings perfectly sharp.
Is my .icns file kept private?
Your file is uploaded over an encrypted connection, converted on our servers and deleted automatically within 24 hours. We never read, share or keep your files, and no account is needed.
