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.
獲得最佳結果的提示
請使用檔案的副本進行操作，並在檢查結果之前保留原件。在提交到入口網站、僱主或機構之前，請開啟輸出並檢視每一頁。如果有大小限制，請確認接收網站如何計算：有些把一千位元組算作 1000 位元組，有些算作 1024 位元組。所有處理都在您裝置上的瀏覽器標籤頁中進行，因此大檔案取決於裝置記憶體，在手機上可能需要更長時間。

常見問題
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.
