What is PDF Text Extraction

PDF files can contain two types of content: actual text objects with character data and coordinates, or scanned images that look like text but are actually pictures. This tool extracts the text layer that already exists in the PDF. It does not perform OCR (Optical Character Recognition) on scanned images.

How to Extract Text from PDF

  1. Select or drag your PDF file into the upload area.
  2. Choose the extraction mode: Readable Text or Preserve Layout.
  3. Select the page range to extract.
  4. Click 'Extract Text' to begin processing.
  5. Review the extracted text in the results area.
  6. Use search to find specific text, or copy and download the results.

Why Some PDFs Cannot Extract Text

Some PDFs appear to have text but cannot be extracted. This is usually because: the PDF is a scanned image (the text you see is actually a picture); the text has been converted to outlines (no character data); the PDF uses custom font encoding without Unicode mapping; or the PDF has permission restrictions. In these cases, OCR recognition may be needed.

Readable Text vs Preserve Layout

Readable Text mode reorganizes text blocks into natural reading order, merges line breaks and restores paragraphs. It is suitable for articles, reports and contracts. Preserve Layout mode keeps the visual arrangement based on text coordinates, preserving indentation and spacing. It is suitable for tables, lists, invoices and complex layouts.

Can PDF Tables Be Extracted

This tool can attempt to preserve the position of table content, but cannot guarantee complete table structure recovery. For complex tables, the Preserve Layout mode may produce better results, but the output is plain text, not a structured table format.

Data & Privacy

All processing is performed entirely in your browser. Your PDF and extracted text are never uploaded to any server. No file content, filenames or metadata leave your device.

Use Cases

  • Extract content from academic papers
  • Copy text from reports and documents
  • Get text from contracts
  • Organize e-book content
  • Extract study materials
  • Search through long PDFs
  • Export text for personal organization
  • Check if a PDF contains a text layer

Limitations

This tool can only extract existing text layers from PDFs. Scanned images require OCR. Complex multi-column documents may have incorrect reading order. PDF tables may not be fully recovered. Original fonts, colors and formatting are not preserved in TXT output. Custom font encoding may produce garbled text. Vertical text and right-to-left text may need manual checking. This is not a PDF-to-Word tool.

Frequently Asked Questions

How do I extract text from a PDF?▼
Upload your PDF, choose the extraction mode and page range, then click 'Extract Text'. Review the results and copy or download them.
Are PDF files uploaded to a server?▼
No. All processing is done entirely in your browser. Your PDF never leaves your device.
Why can I see text in the PDF but cannot extract it?▼
The PDF may be a scanned image where the text is actually a picture, or the text may have been converted to outlines without character data. In these cases, OCR recognition is needed.
Why do scanned PDFs have no extraction results?▼
Scanned PDFs consist of images, not text objects. This tool extracts existing text layers and does not perform OCR.
What is the difference between PDF text extraction and OCR?▼
Text extraction reads existing text data from the PDF. OCR recognizes text from images. This tool does text extraction only.
Can I extract text from specific pages?▼
Yes. You can select all pages, current page, odd/even pages, or enter a custom range like 1-3,5,8-10.
Can I extract text from the entire PDF at once?▼
Yes. Select 'All Pages' to extract text from every page.
Can the original formatting be preserved?▼
Preserve Layout mode attempts to maintain visual arrangement, but fonts, colors and styling are not preserved in the text output.
Can tables be extracted from PDFs?▼
The tool can attempt to preserve table positions, but cannot guarantee complete table structure recovery.
Why is the text order incorrect after extraction?▼
PDF stores text blocks with coordinates, not in reading order. Multi-column layouts or complex arrangements may result in incorrect order. Try different reading order options.
Why do Chinese or special characters appear garbled?▼
The PDF may use custom font encoding or lack Unicode mapping. The garbled text is caused by the PDF itself, not the browser.
Can password-protected PDFs be extracted?▼
This tool cannot process password-protected or encrypted PDFs.
Can I download as TXT?▼
Yes. You can download as TXT, Markdown or JSON format.
Can I download as Markdown or JSON?▼
Yes. All three formats are supported: TXT, Markdown and JSON.
Can I use this on mobile?▼
Yes. The tool works on mobile browsers, but large PDFs are recommended to be processed on desktop.
Does extracting text modify the original PDF?▼
No. The original PDF is never modified. Only the extracted text is displayed and available for download.
Can duplicate headers and footers be removed?▼
The text cleaning tools can help remove extra spaces and blank lines. Automatic header/footer removal is not yet available.
Can I search the extracted results?▼
Yes. Use the search bar to find specific text in the results. Case-sensitive search is supported.
Why do some pages have only a small amount of text?▼
These pages may contain mostly images or have very little text content. Check the page status indicator.
Which mode should I use for multi-column papers?▼
Try Readable Text mode first with different reading order options. If the result is not satisfactory, try Preserve Layout mode.
