About Mini Photo Editor

Mini Photo Editor is an open-source photo editor hosted on GitHub. It uses WebGL to apply effects, filters, and cropping in the browser. The README links to a hosted online version of the editor.

The editor covers common editing tasks, including cropping, perspective correction, resizing, color and light adjustments, blur effects, and a heal brush. According to the README, images are edited locally in the browser and are not uploaded to a backend server. This is the project's own description and has not been independently verified. Supported file formats depend on the browser or platform in use. The README notes that 16-bit images can be opened, but shader processing and downloads are limited to 8-bit because of WebGL limitations.
