Pixelmator, the Lithuania-based firm that makes popular Mac-based photo editing tools, has agreed to be acquired by Apple.

The company says that, pending regulatory approval, there will be "no material changes to the Pixelmator Pro, Pixelmator for iOS, and Photomator apps at this time," but to "Stay tuned for exciting updates to come." The Pixelmator team, now 17 years old, states that its staff will join Apple. Details of the acquisition price were not made public.

Fans of Pixelmator's apps, which are notably one-time purchases, unlike Adobe's tools, may be hoping that those "exciting updates" do not include the sublimation of Pixelmator into an Apple product at some future time, while the Pixelmator apps disappear.

Regulatory approval may not be a rubber stamp. Adobe had to abandon its $20 billion proposed acquisition of design software firm Figma after UK and European Union regulators signaled opposition to the deal and launched investigations. Similar objections from Europe arose over Amazon's attempted purchase of iRobot, while Microsoft's biggest acquisition ever, the $69 billion Activision Blizzard purchase, found a way through.
