从零生成占位图——选择尺寸、颜色和标签文字,导出为 SVG、PNG 或 JPG。无需上传。 100% 本地处理
{width}×{height};占位符替换为实际数值。可输入任意内容,或清空获得空白块。Use SVG when the placeholder will sit in HTML or documentation — it stays sharp at any size and the file is tiny. Use PNG when you need a real raster bitmap (for example to drop into a design tool that does not accept SVG). Use JPG only when file size matters more than crisp edges; it has no transparency and adds slight compression artifacts, so it is rarely the best choice for flat-color placeholders.
