A human tip
The useful version of Deskew Pdf
A conversion tool is most valuable when it removes the work around the conversion. People usually arrive with a destination in mind—an upload, a submission, an email, a report, a website or another editing step. The page should make that destination obvious, keep the interface focused, and offer a sensible next action when the first operation is only part of the job.
About This Tool
校正PDF倾斜使用先进的投影轮廓方差分析自动检测并校正PDF文档中的倾斜或歪斜页面。这对于以一定角度送入扫描仪的扫描文档至关重要。
该工具分析不同角度下的文本和内容对齐情况，找到最佳旋转角度，然后应用校正。您可以调整敏感度阈值（1-30）和DPI设置（72-300）以获得最佳结果。
所有处理都在您的浏览器中使用WebAssembly技术本地进行，确保您的文档保持私密和安全。
How to Use
上传PDF文件
拖放您的扫描PDF文件或点击选择。
配置设置
如需要，调整阈值敏感度和DPI以获得更好的检测效果。
处理并下载
点击校正以拉直页面并下载校正后的PDF。
Use Cases
扫描文档
修复从文档进纸器以一定角度扫描的页面。
手机扫描
校正使用智能手机拍摄的倾斜文档照片。
档案修复

Frequently Asked Questions
角度检测有多准确？+
该工具使用投影轮廓方差分析来检测高达±10度的倾斜角度，具有高精度。它会自动跳过角度小于0.3度的页面。
文本质量会受到影响吗？+
对于90度的倍数旋转，不会发生质量损失。对于其他角度，工具会四舍五入到最近的度数并保持良好的质量。
我可以只校正特定页面吗？+
该工具会分析所有页面，但只校正检测到的倾斜超过敏感度阈值的页面。倾斜最小的页面保持不变。
什么是敏感度阈值？+
值1-10仅校正明显的倾斜，11-20检测中等倾斜，21-30捕获细微角度。默认值为10，用于平衡检测。
处理需要多长时间？+
处理时间取决于文件大小和DPI。150 DPI（默认值）在速度和准确性之间提供了良好的平衡。更高的DPI更准确但更慢。
