About PDF to Text
How Text Extraction Works
The tool reads the text layer from each PDF page, groups characters by position to reconstruct lines and paragraphs, and outputs a plain .txt file. Pages are separated by horizontal rules. If a page has no text layer (like a scanned image), it’s flagged as empty.
Everything runs in your browser. Drop a file, pick your pages, and the text downloads to your device. No account needed, nothing uploaded.
When You Need to Extract Text from a PDF
Sometimes you just need the words, not the formatting.
Content Analysis
Pull text from reports, research papers, or legal documents to search, analyze, or feed into another tool. Plain text is the universal input format.
Data Processing
Need to run regex, NLP, or keyword extraction on a PDF? Extract the text first, then process it with your scripts or AI tools.
Accessibility
Convert a PDF to plain text so it can be read by screen readers, text-to-speech tools, or braille displays without PDF-specific software.
Archiving & Indexing
Extract text from documents to build a searchable index or full-text search database. Plain text indexes faster than PDF.

What You Get (and What You Don’t)
The output is raw text. No bold, no italics, no font sizes, no tables. Paragraphs and line breaks are reconstructed from character positions, which works well for standard documents but may produce odd results on multi-column layouts or complex page designs.
If your PDF is a scanned image with no text layer, this tool will flag the page as having no content. For scanned PDFs, use the PDF to Word tool with OCR enabled instead.
Privacy: Your Document Stays Local
Text extraction runs entirely in your browser. Your PDF isn’t uploaded anywhere. The moment you’re done, your data is gone. This matters when you’re working with confidential contracts, proprietary research, or personal documents.
