PDF to Text Extractor

PDF (Portable Document Format) is a file format designed to preserve document layout across devices and printers. PDFs can contain two kinds of text: (1) embedded text that was generated by a word processor or design tool, which is stored as character data in the PDF structure, and (2) scanned images of text (like a photo of a printed page), which appear as pictures and do not contain searchable character data. This tool extracts only embedded text - the kind you can select and copy in a PDF reader like Adobe Acrobat. If your PDF is a scanned image (e.g., a photo of a contract or book page), you will need OCR (Optical Character Recognition) software to convert the pictures into text; this tool does not include OCR.

The tool uses Mozilla PDF.js, the open-source JavaScript PDF rendering library that powers Firefox's built-in PDF viewer. PDF.js parses the PDF file structure, decodes content streams, and extracts text operators and character mappings from each page. The extracted text is concatenated page by page and displayed in a text area where you can copy it or download it as a .txt file. All extraction happens in your browser - no PDF data is uploaded to a server. This is important for confidential documents like contracts, tax forms, medical records, or internal reports.

PDF text extraction is not perfect for complex layouts. PDFs with multi-column layouts (like newspapers or academic journals) may extract text in the wrong order, because PDF does not store "reading order" - it stores each text fragment with X/Y coordinates. PDF.js heuristically groups text by position, but columns, headers, and sidebars can end up interleaved in the plain text output. Tables in PDFs are especially problematic: they are rendered as positioned text fragments, not as semantic table structures, so extracted table text may be jumbled or misaligned. If you need structured data from a PDF table, consider using a dedicated PDF table extraction tool or manually retyping the table.

Password-protected PDFs (encrypted with a user password) cannot be opened or extracted without the password. This tool does not include a password prompt, so encrypted PDFs will fail to load with an error. If you own the PDF and know the password, unlock it first in Adobe Acrobat or another PDF tool by opening it with the password and re-saving it without encryption. PDFs with permission restrictions (e.g., "printing allowed but copying disallowed") usually can still be extracted because those restrictions are enforced by the PDF reader application, not by encryption of the content.

Worked example: A researcher downloads a PDF research paper from an academic journal. The paper is 20 pages of embedded text (not a scanned image). The researcher wants to extract key quotes for a literature review but does not want to manually retype them. Using this tool, the researcher uploads the PDF, waits a few seconds for extraction, and gets the full text of the paper in a text box. The researcher searches for key terms (Ctrl+F), copies relevant paragraphs, and pastes them into a notes document. Because the extraction was done locally in the browser, the PDF (which may have been downloaded from a paywall site) never left the researcher's laptop.
