常见问题
›Does it work on scanned PDFs?
No — scanned PDFs contain images of text, not selectable text. Use an OCR tool first to convert image-text into selectable text.
›How do I know if my PDF has selectable text?
Open it in any PDF viewer and try to select text. If you can copy individual words, our tool will extract them. If you can only select the whole page as a single image, it's a scan.
›Are my PDFs uploaded?
No — extraction happens entirely in your browser via PDF.js.
›Is the layout preserved?
Approximately — line breaks and column order are best-effort. Complex layouts (multi-column papers, footnotes) may need cleanup.
›Is the extractor free?
Yes — fully free, no signup.
