Zoom & View
Pinch with two fingers to zoom/pan while viewing. Zoom is view-only — it never changes stored annotation coordinates.
Rotate & Flip
Rotate/flip re-bake the image and remap every box exactly (no approximation). "Reset to Original" discards any crop/resize/rotate/flip and all boxes for this image, since they no longer correspond to the original pixels.

Grayscale preview
These only change how the image looks while you label. The exported image pixels are never affected.

Local Save & Project File
Project files store box coordinates and the exact crop/resize/rotate/flip steps applied — not image pixels (browsers can't reliably persist arbitrary files across sessions). After loading a project, re-import the same original image files and TapBox reattaches your work automatically by matching filename + size + modified date.
Resize Prepared Image
Fit + Letterbox: scales the image to fit inside the target size, preserving aspect ratio, and pads the rest with black. No distortion, no cropping.
