HowtoextracttextfromaPDF
Copying out of a PDF reader gives you text with line breaks in the wrong places, hyphens mid-word and columns interleaved. That is not the reader being careless — it is what happens when you ask for a rectangle of positioned glyphs and expect prose.

Why copy and paste goes wrong
A PDF stores each run of characters with coordinates. There is no paragraph, no reading order beyond convention, and no line that knows it continues below. Reconstructing sentences means inferring them from positions.
Walking the text layer page by page and rebuilding lines from vertical positions gets you far closer to readable prose than a selection drag does.
When the file comes back empty
It is a scan. A scanned page is a picture of text with no text layer to read, so there is genuinely nothing to extract.
Turning that picture into text needs OCR — optical character recognition — which is a different operation: it recognises shapes as characters and always involves some error rate. If you need it, that is what to search for; extraction cannot substitute.
What extraction preserves
- Reading order and line breaks — reconstructed, and usually right.
- Non-Latin scripts — the text comes out in whatever the PDF stored and is written as UTF-8, so Hindi, Bengali and Arabic extract correctly.
- What it does not preserve: columns, tables and exact spacing. It is text for reuse, not a visual copy.

Questions people ask
Your PDF is a scan — an image of text with no text layer. Extracting that needs OCR, which this does not do.
