The image is converted to HSL color space, the hue is rotated by the number of degrees you choose (0–360), then converted back to RGB. 90° gives surreal cyans, 180° produces a complementary-color flip, 270° turns greens to magentas — great for psychedelic effects and accessibility checks. Output format matches the input where possible, defaulting to PNG. Conversion runs locally in your browser — files never leave your device.","category":"image","categoryName":"Image","keywords":["image hue rotate","image hue shift","rotate image hue","hue rotate online","image hue tool","online hue rotator","free hue rotate","image color shift","photo hue rotate","hue rotation tool","image color rotator"],"url":"https://freepngtojpg.com/image-hue-rotate","runsOn":"client","multiple":false,"batch":false,"input":{"type":"file","extensions":[".png",".jpg",".jpeg",".webp",".bmp"],"mimeTypes":["image/png","image/jpeg","image/webp","image/bmp"]},"output":{"type":"file","extension":".png","mimeType":"image/png"},"options":[{"type":"number","key":"degrees","label":"Hue rotation (degrees)","defaultValue":90,"min":0,"max":360,"step":1,"help":"0 means no change. 180° gives complementary colors."}],"invocation":{"webUi":"https://freepngtojpg.com/image-hue-rotate","api":null,"notes":"Currently runs client-side in the user's browser.
