Our Story

We wish we had this.

We created this Add-On because we wish we had it. After publishing 50+ KDP books ourselves, we decided to build a better way to resize Google Docs™.

We're a very small team of devs who decided to build things to save ourselves - and others - precious time.

Today, we're proud to serve hundreds of authors - all saving time and focusing on book publishing, not document sizes.
