Convert SVG to ICNS on Mac
Select the SVG files in Finder, press ⌥ F, choose ICNS and press Return. FileFlip saves each ICNS next to its original and works without an internet connection.
How to convert SVG to ICNS with FileFlip
Select the SVG files
In Finder or on the Desktop. One file, or a whole folder with ⌘ A.
Press ⌥ F
FileFlip opens next to the selection and lists the formats it can make from SVG. Type “ICNS” to jump to it.
Choose ICNS and press Return
The ICNS files appear next to the originals with the same names. The SVG files stay as they are.
SVG and ICNS
Many apps, documents and upload forms only accept pixel images, not SVG. ICNS is what macOS uses for app and folder icons.
What changes when you convert
- SVG is a vector format and ICNS stores pixels, so the result has a fixed size and won’t stay sharp when enlarged.
- ICNS holds icon sizes up to 1024 × 1024 pixels, so a square source image of at least that size works best.

Other ways on a Mac
For one file now and then you may not need FileFlip. These work with what’s already on your Mac.
Terminal
The sips command converts images in place or into a new file.
sips -s format icns logo.svg \
--out logo.icnsBuilt into macOS. Use a square image; run sips --formats to check what your macOS version supports.
Questions about SVG and ICNS
Can I convert many SVG files at once?
Yes. Select them all in Finder, press ⌥ F and choose ICNS. Progress moves to the menu bar, so you can close the panel and keep working.
What size should the source image be?
Square, and ideally 1024 × 1024 pixels, the largest size an ICNS file holds.
Where is the ICNS file saved?
Next to the original, with the same name and the .icns extension. The SVG file isn’t changed. In Settings you can choose a different folder instead.
Can I convert ICNS back to SVG?
No. FileFlip opens SVG files but doesn’t save them.
Are my files uploaded anywhere?
No. FileFlip converts files on your Mac and works with the internet turned off.
Convert a whole folder of images at once
FileFlip also handles video, audio, PDFs, documents and data files. Requires macOS 14 Sonoma or later.
