常见问题

适用于扫描版PDF吗？

不适用。扫描版PDF包含的是图像，没有文本层。OCR支持可能在未来添加。

我的PDF会被上传吗？

不会。PDF.js在您的浏览器中本地提取文本。

What text encoding is used in the output file?

The downloaded .txt file is encoded in UTF-8, which supports all languages and special characters. It is compatible with any text editor, code editor, or word processor.

Can I extract text from a specific page only?

All pages are extracted at once. The output is organized page by page, so you can scroll to the section you need and copy only the relevant text. Page-range selection may be added in a future update.

Why is the extracted text garbled or shows strange characters?

PDFs with custom font encodings, symbol fonts, or non-standard character mappings may produce garbled text. This is a known limitation of PDF text extraction — the characters exist in the PDF but their Unicode mapping is non-standard.

Does extracted text preserve bold and italic formatting?

No. Plain text output contains only character content — rich formatting such as bold, italic, font size, colors, and layout are not preserved. All text appears as unstyled UTF-8 characters.

Can I extract text from a password-protected PDF?

No. The PDF must be unlocked before text can be extracted. Use the Unlock PDF tool to remove the password, then extract the text from the resulting unprotected file.

Is there a page limit?

There is no enforced page limit. Very long PDFs — hundreds of pages — may take a few extra seconds to process in the browser, but all pages will be extracted successfully.
