Recipes guide typography, spacing, hierarchy, and color without imposing one rigid template.

Small tool, clear promises

How it stays free and private.

Office files are ZIP packages containing XML, styles, and media. Document Sprinkles reads and edits a narrow set of those parts directly in your browser.

No upload server: Your file bytes never need to leave the browser tab.
No AI bill: Deterministic design rules replace model calls and API keys.
Known boundaries: Unsupported layout changes are reported as skipped, not hidden.
Fresh copies only: The original remains untouched; downloads use a new filename.
