The short version

  • Each has a real cost: GIMP gPLv3 licence requires derivative works to be open-source and freely distributed; Kindle Direct Publishing the 70% royalty band has hard edges: pricing even one cent outside $2.99-$12.99 drops the royalty to 35%, which is a cliff, not a gradual scale, and easy to trigger by accident when adjusting price for a promotion.
  • They diverge on capability: GIMP covers Photo editing, Kindle Direct Publishing covers Free publishing.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

GIMP

  • GPLv3 licence requires derivative works to be open-source and freely distributed
  • Community-driven development with no commercial support tier
  • No native CMYK support for professional print workflows
  • Ecosystem depends on community plugins and scripts for advanced features

Kindle Direct Publishing

  • The 70% royalty band has hard edges: pricing even one cent outside $2.99-$12.99 drops the royalty to 35%, which is a cliff, not a gradual scale, and easy to trigger by accident when adjusting price for a promotion.
  • The delivery fee, roughly $0.15 per megabyte, is deducted on every sale under the 70% tier, so image-heavy or long ebooks lose meaningfully more revenue per sale than a plain-text book at the same list price.
  • KDP Select exclusivity, while optional, is the only route to Kindle Unlimited page-read royalties, so authors face a real trade-off between Amazon-only reach with page-read income and wider distribution without it.
  • Public domain or primarily public-domain content is capped at the 35% royalty regardless of price, so that category of publisher cannot access the higher rate at all.
  • As a single-retailer platform, an author relying solely on KDP is concentrated in one sales channel controlled entirely by Amazon policy, which has changed royalty terms before (the July 2026 price band expansion is itself an example) and can do so again.
