画像の回転 — Rotate Image turns photos and scans by right angles — 90° clockwise, 180°, or 270° (the same as 90° counter-clockwise). The pixels are redrawn on a canvas at the new orientation, so a sideways phone photo becomes upright in one click.
Your image is rotated locally in your browser and never uploaded.

画像の回転とは？
Rotate Image turns photos and scans by right angles — 90° clockwise, 180°, or 270° (the same as 90° counter-clockwise). The pixels are redrawn on a canvas at the new orientation, so a sideways phone photo becomes upright in one click.
Because the work happens on your device, even large photos process instantly and nothing is uploaded. The result is saved as PNG, which is lossless: rotating and saving repeatedly never degrades the image.
