IconSizeS for Mac

What IconSizeS does

Prepare iOS, macOS and watchOS outputs
Choose the icon outputs you need, plus optional ICNS, then preview Standard, Dark and Monochrome appearances.
Inspect files at their actual pixel size
Open each prepared file at its real pixel size to see what it contains and any warnings or limits.
Compare with one earlier icon set
Open one supported older set in read-only mode and see which matching images are missing or unclear.
Export only the files you reviewed
Choose a folder and export the prepared files. Each file shows whether it was saved and read back.
Save an HTML or JSON handoff report
The report lists the inspected files and their limits, so the person receiving them has the same details.

Does it change my original files?

Comparison opens an earlier icon set in read-only mode and does not change your source. Changing the source or targets means preparing a fresh set.

Does it draw icons or batch-process sources?

No. It works on one finished artwork source at a time and does not draw icons, edit layers or batch-process multiple sources.

Does it change my Xcode project?

No. It does not change Xcode projects automatically.
