Why convert ICNS to TIFF?
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.
TIFF is a long-established image format for archiving, scanning and print workflows, and it holds the rendered page at full resolution.
Frequently Asked Questions
How do I convert ICNS to TIFF?
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 TIFF image, ready to download.
Which icon size from the ICNS set is used for the TIFF?
The largest one in the file. A modern ICNS usually holds a 1024 × 1024 Retina icon, and that is the image the TIFF is made from.
Can classic ICNS icons without PNG data become a TIFF?
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 TIFF image from a ICNS file?
The largest image stored in the icon set is used, so the TIFF is as detailed as the icon allows.
Is the TIFF from a ICNS file a single image?
Each rendered page is saved as its own standard TIFF image at full resolution. When there are several pages you receive one TIFF per page in a ZIP, numbered in order.
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.
