pypdfsuit
Python bindings for gopdfsuit - a comprehensive PDF library for generation, merging, splitting, form filling, HTML to PDF/Image conversion, compression, and redaction.
Features
- PDF Generation: Create PDFs from structured templates with tables, images, and styled text
- PDF Merging: Combine multiple PDFs into a single document
- PDF Splitting: Split PDFs by pages, ranges, or maximum pages per file
- Form Filling: Fill PDF forms using XFDF data
- HTML to PDF: Convert HTML content or URLs to PDF documents (pure-Go, no browser needed)
- HTML to Image: Convert HTML content or URLs to images (PNG, JPG)
- PDF Compression: Compress PDFs with Light/Medium/Heavy tiers, no Ghostscript needed
- PDF Redaction: Securely redact sensitive information using coordinates or text search
Installation
From Source
- Build the shared library locally:
cd bindings/python
chmod +x build.sh
./build.sh
On Windows, use the batch file instead:
cd bindings\python
build.bat
- Install the Python package:
pip install .
Windows Note
There is currently an issue on Windows. Please build the application locally.
Sample data for the Python bindings is available here:
Requirements
- Python 3.8+
- Go 1.26.4+ (for building the shared library)
- No browser or Ghostscript needed - HTML conversion is pure-Go via gowkhtmltopdf
Quick Start
Generate a PDF
from pypdfsuit.builder import TemplateBuilder, Font
b = TemplateBuilder("A4", True)
b.add_title("My Document", font="Helvetica", size=24, bold=True)
tb = b.add_table(2, 1.0, 1.0)
tb.add_row(
Font("Helvetica").size(12).bold().cell("Name"),
Font("Helvetica").size(12).cell("John Doe"),
)
pdf_bytes = b.generate()
with open("output.pdf", "wb") as f:
f.write(pdf_bytes)
Prefer raw templates? generate_pdf also accepts a hand-built PDFTemplate
(low-level; the builder above is preferred):
from pypdfsuit import generate_pdf, PDFTemplate, Config, Title
from pypdfsuit.builder import make_props
template = PDFTemplate(
config=Config(page="A4", page_alignment=1),
title=Title(
props=make_props("Helvetica", 24, bold=True, align="center", borders=(0, 0, 0, 0)),
text="My Document"
),
elements=[]
)
pdf_bytes = generate_pdf(template)
Merge PDFs
from pypdfsuit import merge_pdfs
with open("doc1.pdf", "rb") as f1, open("doc2.pdf", "rb") as f2:
merged = merge_pdfs([f1.read(), f2.read()])
with open("merged.pdf", "wb") as f:
f.write(merged)
Split a PDF
from pypdfsuit import split_pdf, SplitSpec
with open("document.pdf", "rb") as f:
pdf_data = f.read()
# Split specific pages
spec = SplitSpec(pages=[1, 3, 5])
parts = split_pdf(pdf_data, spec)
# Or split every 5 pages
spec = SplitSpec(max_per_file=5)
parts = split_pdf(pdf_data, spec)
for i, part in enumerate(parts):
with open(f"part_{i+1}.pdf", "wb") as f:
f.write(part)
Convert HTML to PDF
from pypdfsuit import convert_html_to_pdf, HtmlToPDFRequest
# Convert HTML string
request = HtmlToPDFRequest(
html="<html><body><h1>Hello World</h1></body></html>",
page_size="A4",
orientation="Portrait",
)
pdf_bytes = convert_html_to_pdf(request)
# Or convert a URL
request = HtmlToPDFRequest(
url="https://example.com",
page_size="Letter",
)
pdf_bytes = convert_html_to_pdf(request)
Fill a PDF Form
from pypdfsuit import fill_pdf_with_xfdf
with open("form.pdf", "rb") as f:
pdf_data = f.read()
with open("data.xfdf", "rb") as f:
xfdf_data = f.read()
filled = fill_pdf_with_xfdf(pdf_data, xfdf_data)
with open("filled.pdf", "wb") as f:
f.write(filled)
Redact a PDF
from pypdfsuit import apply_redactions_advanced
with open("document.pdf", "rb") as f:
pdf_data = f.read()
redacted = apply_redactions_advanced(pdf_data, {
"blocks": [
{"pageNum": 1, "x": 120, "y": 620, "width": 180, "height": 24}
],
"textSearch": [
{"text": "Confidential"}
],
"mode": "visual_allowed"
})
with open("redacted.pdf", "wb") as f:
f.write(redacted)

Props String Format
Cells and titles carry a props string:
FontName:FontSize:StyleCode:Alignment:BorderLeft:BorderRight:BorderTop:BorderBottom
- FontName: Helvetica, Courier, Times-Roman, etc.
- FontSize: Integer size in points
- StyleCode: 3 digits for bold(1/0), italic(1/0), underline(1/0). e.g., "100" = bold only
- Alignment: left, center, right
- Borders: 1 = border, 0 = no border
Example: "Helvetica:12:100:center:1:1:1:1" = Helvetica 12pt, bold, centered, all borders
You rarely need to hand-write these: the fluent builder spells the same string.
from pypdfsuit.builder import Font, make_props
Font("Helvetica").size(12).bold().center().bordered().cell("Name")
# same bytes as Cell(props="Helvetica:12:100:center:1:1:1:1", text="Name")
make_props("Helvetica", 12, bold=True, align="center", borders=(1, 1, 1, 1))
