解锁PDF（移除密码）
移除密码，让您可以自由使用自己的文件。
使用流程
1. Upload your file
Drag and drop or choose a PDF file from your device. Everything is checked against its real file type before processing starts.
2. We process it
Your file runs through an isolated job dedicated to 解锁 PDF, with clear progress so you always know what stage it's at.
3. Download the result
Get your finished PDF file with one click. The original upload and the result are deleted automatically afterward.
您的文件将保持私密
解锁 PDF 在隔离的处理任务中运行。您上传的文件和生成的结果会在下载有效期结束后自动删除——我们不会保留任何副本,下载链接也是随机生成、仅限单次使用且会过期的。

No. This tool removes a password you already know from a PDF you have access to — it isn't a password-cracking or brute-force tool, and we don't attempt to guess passwords on anyone's behalf.
