How to Extract Text from a PDF — Instantly and Privately
PDF files are everywhere — contracts, research papers, ebooks, invoices — but copying text out of them is often a frustrating experience. Some PDF viewers don't allow selection, others produce garbled output when you paste, and cloud-based converters require you to upload private documents to a third-party server. This free PDF to Text extractor solves all of that. Drop in your PDF and the tool reads it locally using Mozilla's pdf.js library, extracting the raw text from every page without ever sending your file anywhere.
The extraction process works page by page, so you see progress in real time. Once complete, you can view the full document in one continuous block or switch to "View by Page" mode to jump directly to the text from a specific page. Copy to clipboard with one click, or download the entire extracted text as a clean .txt file named after your PDF. Everything runs in your browser — closing the tab discards all data permanently.
Frequently Asked Questions
What types of PDFs does this tool work with?
This tool works with any text-based PDF — documents created digitally in Word, Google Docs, LaTeX, InDesign, or any software that generates native PDF text. It also works with many modern PDFs exported from websites or apps. The tool extracts the actual embedded text characters, so output quality is excellent for standard digital PDFs.
Why is the extracted text empty or garbled for some PDFs?
If the text is empty, garbled, or shows only symbols, the PDF is likely scanned (image-based). Scanned PDFs are essentially photos of pages — there is no embedded text for any tool to extract. These require OCR (Optical Character Recognition) software such as Adobe Acrobat, Tesseract, or an online OCR service. This tool cannot process image-only PDFs. Similarly, PDFs with custom or embedded fonts may occasionally produce character mapping issues — these are limitations of the PDF format itself.
Is my PDF file private? Does it get uploaded anywhere?
Completely private. This tool is a static HTML page — there is no backend server, no database, and no file upload of any kind. Your PDF is read locally by your browser using the open-source pdf.js library. The file content and extracted text never leave your device. This makes it safe to use with confidential contracts, legal documents, medical records, or any sensitive material. Close or refresh the tab and all data is gone.
How accurate is the text extraction?
For standard digital PDFs, extraction accuracy is very high — you get the exact text embedded in the file. Layout and formatting (columns, tables, headers, footers) will not be preserved, as the output is plain text. Text extracted from multi-column layouts may appear merged on a single line. The page separator markers (── Page N ──) help you orient where each page's content begins. For precise formatting preservation, consider converting to Word or using a full-featured PDF editor.
What file formats can I export the extracted text as?
You can copy the extracted text directly to your clipboard, or download it as a .txt file named after your original PDF. The text file uses UTF-8 encoding, making it compatible with all major text editors, word processors, and code editors. If you need the text in a Word document or other format, paste the .txt content into your preferred application. Markdown-compatible editors will also accept the plain text as-is.

如何从PDF中提取文字——快速且完全私密
PDF 文件无处不在——合同、论文、电子书、发票——但从中复制文字往往令人头疼。有些 PDF 阅读器不允许选中,有些粘贴后乱码,还有些在线工具要求你把文件上传到第三方服务器,存在隐私隐患。这款免费的 PDF 转文字工具 彻底解决了这些问题。将 PDF 拖入工具,它会在本地使用 Mozilla pdf.js 库逐页提取文字,全程不上传任何文件。
本工具适用于所有数字文本型 PDF,即通过 Word、Google Docs、WPS、LaTeX、InDesign 等软件直接生成的 PDF 文件。这类 PDF 内嵌了真正的文字字符,提取效果优秀。网页打印为 PDF、报告导出为 PDF 等同样支持。
为什么提取出来的文字是乱码或空白?
如果提取内容为空或显示乱码,说明该 PDF 是扫描件(图片型 PDF)——本质上是拍摄纸质文件后生成的图片,没有内嵌任何文字。这类文件需要 OCR(光学字符识别)工具才能提取文字,例如 Adobe Acrobat、Tesseract 或在线 OCR 服务。此外,部分使用自定义嵌入字体的 PDF 也可能出现字符映射错误,这属于 PDF 格式本身的限制。
我的 PDF 文件会被上传到服务器吗?
完全不会。本工具是纯静态 HTML 页面,没有后端服务器、没有数据库、没有任何文件上传操作。你的 PDF 由浏览器在本地通过开源的 pdf.js 库读取,文件内容和提取出的文字从不离开你的设备。可以放心使用保密合同、法律文件、医疗记录等敏感材料。关闭或刷新页面后,所有数据立即清除,不留任何痕迹。
提取的文字准确吗?格式会保留吗?
对于标准数字型 PDF,文字提取准确率很高,能够获得文件中嵌入的原始文字。但需注意,版面和格式(分栏、表格、页眉页脚)不会被保留,输出为纯文本。多栏排版的内容可能在同一行合并显示。每页之间会插入分页标记(── 第 N 页 ──),方便定位。如需保留精确格式,建议使用 Adobe Acrobat 等完整 PDF 编辑器。
可以下载提取的文字吗?
可以。点击「下载 TXT」按钮即可将提取的全部文字下载为 .txt 文件,文件名与原始 PDF 保持一致,采用 UTF-8 编码,与所有主流文本编辑器、办公软件和代码编辑器兼容。你也可以点击「复制全部」直接将文字复制到剪贴板,然后粘贴到任意应用中使用。
