The selected pixels are decoded into an HTML canvas, transformed at source resolution, and encoded into the chosen output format. Batch mode applies one bounded resize and quality policy to every selected file.
Solid-color background removal compares pixel color distance and is not semantic subject segmentation. Complex backgrounds, fine hair, transparency, metadata, and print workflows should be checked in a dedicated image editor.
Questions
Image Rotator and Flipper FAQ
Why do width and height swap?
A 90- or 270-degree rotation turns the pixel rectangle, so the output width becomes the original height and vice versa.
Is EXIF orientation retained?
The browser decodes the displayed orientation and the exported pixels use that rendered result. Other metadata is not copied into the new file.
