About this tool
A download that stopped half-way, or a broken file structure, can make a PDF refuse to open. This tool rebuilds the structure to make it readable again.
When to use it
Try repair when a PDF will not open, shows an error or opens blank. The tool rebuilds the file structure and saves the pages it can read.
Tips
Keep the original. If some pages are missing in the result, the damage was in the data itself. Re-download or re-send the file from the source if you can.
Privacy
Everything runs in your browser, so your data is not uploaded or stored.
获得最佳结果的提示
请使用文件的副本进行操作，并在检查结果之前保留原件。在提交到门户网站、雇主或机构之前，请打开输出并查看每一页。如果有大小限制，请确认接收网站如何计算：有些把一千字节算作 1000 字节，有些算作 1024 字节。所有处理都在您设备上的浏览器标签页中进行，因此大文件取决于设备内存，在手机上可能需要更长时间。

常见问题
Will every damaged file be fixed?
No. A broken structure is often fixable, but content that is truly lost cannot be brought back.
Can it fix a password-protected file?
No. Remove the password first with the "Unlock PDF" tool.
Will it always work?
No. Light damage often repairs well. A file with missing data cannot be fully recovered.
Is the original changed?
No. A new repaired file is created.
