Does rotating degrade the image?

90° steps are exact geometry — every pixel is preserved, just repositioned. Only the export format's compression applies.

Can I mirror and rotate together?

Yes — combine either mirror with any rotation; the preview shows the exact result.

No — it's a canvas transform on your device.

Rotate an image in 90° steps and mirror it horizontally or vertically, with instant preview — no upload, no quality games.
