PDF修復

開けなくなったファイルを再構築します。

TLSで当社サーバー上で処理 — 変換後すぐに削除されます

Bring back a PDF that refuses to open: “file is damaged”, blank pages, endless loading. The repair engine rebuilds the document structure — cross-reference tables, object streams, page tree — from whatever survived.

Repair runs on our server with a professional PDF engine and the file is deleted immediately after the rebuilt copy is delivered.

使い方

1

Drop the broken PDF into the box above.

2

The engine rebuilds the file structure.

3

Download the repaired copy.

このツールの特長

Fixes structural damage

Broken cross-reference tables, truncated downloads and mangled email attachments are the classic cases this repairs.

Keeps everything that survived

Intact pages, fonts and images are carried over exactly; nothing readable is thrown away.

Deleted right after

The damaged file and its repaired copy exist on the server only for the seconds the rebuild takes.

よくある質問

Can every broken PDF be repaired?

No — if the actual page data is missing (a half-downloaded file), no tool can invent it. But structural damage, which is the most common case, usually repairs cleanly.

The file opens but looks wrong — will repair help?

Often yes: rendering glitches are frequently caused by malformed structure that viewers tolerate differently. A rebuild normalizes the file.

Will I lose quality?

No. Repair rewrites the file structure; page content that survived is copied as-is.

What happens to my file on the server?

Processed over TLS in temporary storage, deleted the moment your download is ready.
