What this tool does

This tool turns a picture by 90, 180 or 270 degrees and can flip it horizontally or vertically, with a live preview so you can see the result before downloading.

The everyday use is fixing orientation: a phone photo that came out sideways or upside down, a scan that needs turning, or an image that should be mirrored to face the other way.

Your image never leaves your device, so nothing is uploaded when you rotate or flip.

Flip and rotate together

Flips and rotation combine, so you can mirror an image and turn it in a single step, which covers the common case of an image that is both reversed and rotated.

Quality and clean edges

Rotation in 90-degree steps is lossless on the pixels, since it simply rearranges them. If you export to JPEG the file is re-encoded at high quality; choose a PNG for fully lossless output.

It rotates in fixed 90-degree steps and flips, rather than straightening by an arbitrary angle, which keeps the result crisp with no blurry edges or added borders.

How it runs

Everything runs in your browser with the Canvas API, so it is fast and there is no waiting on a server.

常见问题

我的图片会被上传到任何地方吗?

不会。旋转完全在你的浏览器中使用 Canvas API 进行,因此你的图片永远不会离开你的设备。

旋转会降低质量吗?

旋转 90、180 或 270 度对像素是无损的。JPEG 输出会以高质量重新编码;如需完全无损的输出,请使用 PNG 输入。

我能同时翻转和旋转吗?

能。翻转和旋转可以组合,因此你可以一步镜像并旋转图片。
