Exporting for Every Platform: A Practical Checklist

One layered source file should feed every destination — that's the whole point of keeping layers. The mistake is exporting to each platform by hand, from memory, differently each time. Exports should be a checklist you run, not a craft you perform.

For web, export at 1x and 2x and let the page pick; for iOS add 3x; for Android map to the density buckets rather than inventing your own scales. For print, flatten a copy, convert color profiles deliberately, and never let the layered master leave RGB.

Write your checklist down inside the project itself — a locked 'export-notes' layer costs nothing and rides along with the file forever. Six months from now, the person who needs those settings will probably be you.
