PDF Privacy Checker — frequently asked questions
Does this fix the problems it finds?+
No — it only reports them. Click "Clean this PDF" on the result to send the same file straight to Sanitize PDF, which removes what it can.
Is the scan itself uploaded anywhere?+
No. Like every tool on the site, the PDF is read entirely in your browser — checking it never sends the file anywhere either.
Can it read GPS coordinates from a scan?+
It flags when a document carries an extended XMP metadata block, which is where that kind of detail can live, without trying to parse every possible field — that's a plain-English early warning, not a forensic report.
What counts as "exposed" vs "worth a look"?+
Embedded JavaScript, auto-run actions, and attached files are flagged as exposed — they carry real risk if opened in a full desktop PDF reader. Author names, dates, comments and form fields are flagged as worth a look — usually harmless, but not always what you'd want a stranger to see.
你們會把我的檔案上傳到伺服器嗎？+
不會——這裡的每個工具都完全在你的裝置上處理檔案，不會向伺服器上傳任何內容。唯一的例外是 AI 工具，它們會把擷取的文字（而非檔案本身）傳送給 Claude 來完成工作。
有檔案大小限制嗎？+
我們沒有人為設下限制，但由於處理過程在你的瀏覽器中進行，非常大的檔案（超過 500MB 或 1000 頁）會受你裝置記憶體的限制，而非我們的限制。
