Rotate & Flip Image — what it does
Rotate an image by a chosen angle and flip it horizontally or vertically, then download the corrected version. It fixes the two most common orientation problems in one place: a photo lying on its side because a phone's orientation tag was ignored, and a scan or selfie that came out mirrored.
When this tool helps
- Straightening a photo that displays sideways after being uploaded somewhere.
- Un-mirroring a selfie or a scanned page that came out reversed.
- Rotating a scanned document to reading orientation before archiving it.
How to use it
- Choose the image.
- Select the rotation angle.
- Tick horizontal or vertical flip if needed.
- Process and download the corrected image.
Accuracy, limits, and good practice
- Rotation here rewrites the actual pixels, so the result displays correctly everywhere — unlike an EXIF orientation tag many viewers ignore.
- Flipping mirrors the image, which reverses any text in the picture; that is the giveaway if you flip a document by mistake.
- Rotating by 90 degree steps is lossless in terms of geometry; the file is re-encoded, so export at high quality.
Frequently asked questions
Why do photos appear sideways in some apps?
The camera stored the picture in one orientation and recorded a rotation tag. Software that ignores the tag shows the raw orientation.
Does flipping change image quality?
The pixel operation is exact; only re-encoding to a lossy format affects quality.
Can I rotate by an arbitrary angle?
The standard rotations cover the common orientation fixes. Small corrective angles need an editor with crop-and-straighten.

圖片旋轉與翻轉能做什麼
把圖片依選定角度旋轉，並可水平或垂直翻轉，再下載修正後的版本。它一次解決兩個最常見的方向問題：手機方向標記被忽略而躺倒的照片，以及左右相反的掃描或自拍。
什麼時候用得上
- 修正上傳到某處後顯示成橫躺的照片。
- 把左右相反的自拍或掃描頁面翻回來。
- 把掃描文件轉成可閱讀的方向再封存。
使用步驟
- 選擇圖片。
- 選擇旋轉角度。
- 視需要勾選水平或垂直翻轉。
- 執行處理並下載修正後的圖片。
精確度、限制與實務建議
- 此處的旋轉會實際改寫像素，因此到哪裡顯示都正確——不像許多檢視器會忽略的 EXIF 方向標記。
- 翻轉會鏡像畫面，圖中的文字會左右相反；不小心翻到文件時，這就是最明顯的破綻。
- 以 90 度為單位旋轉在幾何上無損；檔案會重新編碼，請以高品質匯出。
常見問題
為什麼照片在某些 App 裡是橫的？
相機以某個方向儲存畫面並另外記錄旋轉標記，不理會該標記的軟體就會顯示原始方向。
翻轉會影響畫質嗎？
像素運算本身精確，只有重新編碼成有損格式才會影響畫質。
可以旋轉任意角度嗎？
標準角度已涵蓋常見的方向修正。細微校正角度需要具備裁切拉直功能的編輯器。
