The Yahoo-owned firm said that it has taken user feedback on board and focused on "speed" and "simplicity" with the new interface.
"Tens of thousands of members edit their photos on Flickr each day, so we know that photo editing is something that the Flickrverse cares about," the firm said in a statement.
"We listened to you to find out what you value the most in an online photo editor, and the same two attributes kept coming back: speed and simplicity."
Flickr promised that the overhauled editor will enable users to alter their photographs in "seconds" and help newcomers acclimatise swiftly with an undemanding learning curve.
In February, Flickr rolled out a major redesign of its user interface in a bid to claim marketshare from rivals such as Facebook, Twitter, Google+ and the fast-growing Pinterest.
The new editing tool was written in HTML5, making it compatible with the Apple iPad as well as home computers.
