Arabic PDF text extraction with ligature and RTL fixes

PDF2Text-Arabic

Arabic PDF text extraction built on PyMuPDF. Fixes ligature decomposition, RTL ordering, table extraction, and other issues that make raw PyMuPDF output unusable for Arabic.

What it fixes

#	Problem	Fix
1	Ligature decomposition — PyMuPDF breaks Arabic ligatures (الله, لأ, لإ) into LTR-ordered zero-width chars	Detects zero-width clusters, reverses to RTL order
1b	Lam-Alef swap — لا ligature decomposed as ال (alef before lam)	Detects width ratio, swaps to correct order
2	Presentation Forms — Returns U+FB50–FDFF / U+FE70–FEFF instead of standard Arabic	NFKC normalization
3	Line splitting — One visual line split into multiple rawdict lines at same y	Y-coordinate merging with tolerance
4	Number reversal — RTL sorting reverses digit sequences (2019 → 9102)	Detects LTR digit runs, reverses back
5	Arabic↔digit spacing — No space between Arabic text and numbers	Regex-inserts spaces at boundaries
6	Artifact spaces — Space chars with overlapping bboxes cause false word breaks	Only honors spaces with physical gaps > 0.5px
7	Invisible chars — Zero-width joiners, BOM, LTR/RTL marks, kashida	Stripped in post-processing

Install

pip install pdf2text-arabic

pip install .
# or with uv
uv pip install .

Quick start

Python API

from pdf2text_arabic import extract_pdf, extract_page

# Extract entire PDF
text = extract_pdf("document.pdf")

# With cropping (remove headers/page numbers)
text = extract_pdf("document.pdf", crop_top=50, crop_bottom=30)

# Crop by percentage
text = extract_pdf("document.pdf", crop_top=5, crop_bottom=3, crop_unit="pct")

# Disable footnote separator detection
text = extract_pdf("document.pdf", detect_footer=False)

AI-friendly API (recommended for agents)

from pdf2text_arabic import extract_pdf_result, get_capabilities

caps = get_capabilities()
result = extract_pdf_result("document.pdf", on_empty="warn")

print(result.pages_total)
print(result.pages_with_text)
print(result.empty_pages)
print(result.warnings)
print(result.text)

Agent contract:

• Prefer extract_pdf_result() over parsing logs.
• Do not manually reorder Arabic text after extraction.
• Use get_capabilities() before enabling OCR-specific behavior.

Single page

import fitz
from pdf2text_arabic import extract_page

doc = fitz.open("document.pdf")
text = extract_page(doc[0], crop_top=50, crop_bottom=30)
doc.close()

CLI

# Process all PDFs in a directory
pdf2text-arabic -i ./download -o ./output/plain_text

# Single file
pdf2text-arabic -f document.pdf -o ./output

# With cropping
pdf2text-arabic -i ./download --crop-top 50 --crop-bottom 30

# Crop by percentage, no footer detection
pdf2text-arabic -i ./download --crop-top 5 --crop-bottom 3 --crop-unit pct --no-footer

API reference

extract_pdf(pdf_path, **kwargs) → str

Extract text from all pages of a PDF.

Parameter	Type	Default	Description
pdf_path	str	—	Path to the PDF file
crop_top	float	0	Crop from top of each page
crop_bottom	float	0	Crop from bottom of each page
crop_unit	"px" | "pct"	"px"	Unit: points or percentage of page height
detect_footer	bool	True	Auto-detect footnote separator lines and exclude content below

extract_page(page, **kwargs) → str

Extract text from a single fitz.Page. Same parameters as extract_pdf (except pdf_path).

extract_pdf_result(pdf_path, **kwargs) → ExtractionResult

Structured output for AI/automation:

• text: final extracted text
• pages_total: total page count
• pages_with_text: number of non-empty extracted pages
• empty_pages: list of page numbers that produced empty output
• warnings: machine-readable warning tokens (example: empty_page:3)

Features

Table extraction

Tables are automatically detected via PyMuPDF's find_tables(), extracted with proper Arabic cell ordering, and formatted as pipe-delimited text. Merged cells are filled down so every row is self-contained:

الجهات | عدد المقاعد | مقر الدائرة الانتخابية
طنجة – تطوان – الحسيمة | 2 | ولاية جهة فاس - مكناس
الشرق | 2 | ولاية جهة فاس - مكناس
فاس - مكناس | 2 | ولاية جهة فاس - مكناس

Footer detection

Automatically detects horizontal separator lines (both vector drawings and text-based dashes) in the bottom 40% of each page and excludes footnote text below them. Handles non-selectable drawn lines and selectable ------ text.

Page cropping

Crop headers and page numbers by fixed pixel amount or percentage of page height.
