▱ 图片倾斜变形（水平 / 垂直斜切）Skew Image (Horizontal & Vertical Shear)
把图片沿水平或垂直方向斜切变形（−60° 到 60°），做出平行四边形、斜体、透视感的效果；画布自动扩大以完整保留图片，空出的部分可设为透明或任意背景色。支持批量和 PNG / JPG / WebP 输出，图片只在浏览器本地处理。Skew (shear) an image horizontally or vertically from −60° to 60° for parallelogram, italic or faux-perspective effects. The canvas grows so the whole image is kept, and the empty corners can be transparent or any background colour. Works in bulk with PNG, JPG or WebP output, and images are processed locally in your browser.

如何使用「图片倾斜变形（水平 / 垂直斜切）」？How do I use the Skew Image (Horizontal & Vertical Shear) tool?
在「图片倾斜变形（水平 / 垂直斜切）」中，选择或拖入文件，按需设置「水平倾斜」、「垂直倾斜」、「空白处」、「背景色」、「输出格式」等选项，然后点击每个结果旁的「下载」按钮即可；有多个文件时也可以点「全部下载（ZIP）」一次打包下载。In the Skew Image (Horizontal & Vertical Shear): Choose or drop your files, set "Horizontal skew", "Vertical skew", "Empty areas", "Background", "Format", then click the Download button next to each result (with several files, "Download all (ZIP)" saves them together).
倾斜角度是什么意思？What does the skew angle mean?
水平倾斜会让图片的上下边保持水平、左右边倾斜指定角度（正值向右下倾斜，负值反方向）；垂直倾斜则让左右边保持竖直、上下边倾斜。两者可以同时使用。45° 时，每往下一行就向右移动一个像素，画布宽度会增加图片的高度。A horizontal skew keeps the top and bottom edges level and tilts the sides by the angle (positive leans one way, negative the other); a vertical skew keeps the sides upright and tilts the top and bottom. You can use both together. At 45°, each row moves one pixel further across, so the canvas gets wider by the image height.
为什么图片变大了？Why is the output bigger?
斜切后图片变成平行四边形，为了不裁掉任何部分，画布会扩大到能完整容纳它的大小，多出来的三角形区域按“空白处”设置填充为透明或背景色。JPG 不支持透明，选透明时会填白色。After skewing, the image is a parallelogram, so the canvas grows to hold all of it without cropping. The extra triangles are filled according to Empty areas — transparent or a background colour. JPG has no transparency, so transparent areas become white there.
支持哪些图片？会上传吗？Which images work, and are they uploaded?
支持 JPG、PNG、WebP、GIF（静态或动图的第一帧）、BMP、AVIF、HEIC，以及浏览器能打开的 SVG；可一次拖入最多 50 张批量处理，单张最大 60 MB、1 亿像素；多张结果可打包成 ZIP 下载。所有处理都在你的浏览器里完成，图片不会上传，结果中也不会保留 EXIF 等元数据（包括拍摄位置）。JPG, PNG, WebP, GIF (a still or the first frame of an animation), BMP, AVIF, HEIC, and SVG that the browser can open. Drop in up to 50 images at once; each can be up to 60 MB and 100 megapixels, and several results can be downloaded as a ZIP. Everything happens in your browser: images are not uploaded, and EXIF and other metadata (including location) is not kept in the results.
