Understanding PDF Text Extraction
This tool uses PDF.js, an open-source PDF rendering library developed by Mozilla, to parse PDF files and extract embedded text. It works only with text-based PDFs — documents where the text is stored as selectable characters, not as images. If the PDF was created from a word processor or exported from a design app, the text is usually extractable.
Scanned PDFs (created from photographs or scans of paper documents) contain only images, not text. For those, use our Bangla OCR or Scan to Unicode tools, which use optical character recognition to identify text from images. All processing happens in your browser, so your PDF never leaves your device — making this tool safe for confidential documents.
Common PDF Extraction Problems & Fixes
| Problem | Cause | Fix |
|---|---|---|
| No text extracted — output is empty | The PDF is scanned (image-based) rather than text-based, so there is no selectable text to extract. | Use our Bangla OCR or Scan to Unicode tool instead — those use OCR to recognize text from images of scanned pages. |
| Extracted text is garbled or shows wrong characters | The PDF uses a custom font encoding that does not map to standard Unicode code points. | This is a limitation of the source PDF. Try opening the PDF in Adobe Acrobat and using its built-in text export, or use OCR on a rendered image of each page. |
| Extracted text has wrong line breaks | PDF text extraction reconstructs lines based on text positioning, which may differ from the visual layout. | After extraction, review and fix line breaks manually. For paragraphs that are split across lines, remove the extra newlines and join them into proper paragraphs. |
| Some pages produce no text while others work fine | Those pages may be scanned images embedded in the PDF rather than text-based content. | Use a screenshot tool to capture the image-based pages, then run them through our Bangla OCR or Scan to Unicode tool for text recognition. |
Frequently Asked Questions
Does it work with scanned PDFs?
No. Scanned PDFs contain images, not text. For scanned documents, use the Bangla OCR or Scan to Unicode tool which uses OCR technology to recognize text from images.
Is my PDF uploaded to a server?
No. All processing happens in your browser using PDF.js. Your PDF never leaves your device, making this tool safe for sensitive or confidential documents.
Why does the extracted text contain boxes or question marks?
The PDF was likely created with an embedded font that does not map cleanly to Unicode, or your browser lacks a Unicode Bangla font. Install Noto Sans Bengali to display the text. If the boxes persist, the PDF uses a custom font encoding that cannot be extracted as text — try OCR instead.
Can I extract text from a password-protected PDF?
No. PDF.js cannot open password-protected PDFs in this tool. Remove the password protection in Adobe Acrobat or your PDF editor first, then upload the unprotected file.
Does it preserve formatting, tables, and images?
No. This tool extracts plain text only. Formatting (bold, italic, font sizes), tables, and images are not preserved. The output is plain Unicode text suitable for copying into a text editor or word processor.
Is there a file size limit?
There is no hard limit, but very large PDFs (hundreds of pages) may take longer to process and use more memory. The tool runs in your browser, so performance depends on your device. For extremely large PDFs, consider splitting the file first.
Is this PDF to Unicode tool free?
Yes, completely free. No registration, no daily limit, no file count cap. All extraction happens in your browser using PDF.js — there is no server-side processing. You can use it unlimited times for personal, educational, or commercial work.
Can I extract text from multiple PDFs at once?
Currently, the tool processes one PDF at a time. To extract text from multiple PDFs, process each file separately and combine the results manually. We are working on adding batch processing support in a future update.
