PDFluent Examples

Runnable examples for the PDFluent SDK, a pure-Rust PDF SDK.

Working code examples for the PDFluent SDK, a pure-Rust PDF SDK with XFA, PDF/A, digital signatures, and redaction, with bindings for Rust, Python, Node.js, WASM, .NET, and Java.

This repository currently has Rust examples and a browser/WASM demo. For the other languages, see the install snippets and docs linked below.

Quick start

git clone https://github.com/pdfluent/examples
cd examples/rust
cargo run --example text_extraction -- ../sample.pdf

Examples

Example	What it shows	Language	How to run
text_extraction	Open a PDF, extract all text, iterate page by page	Rust	cargo run --example text_extraction -- ../sample.pdf
form_fill	Fill AcroForm text fields and checkboxes, then flatten to static PDF	Rust	cargo run --example form_fill -- in.pdf out.pdf
merge_pdfs	Merge multiple PDFs into one with a shared bookmark structure	Rust	cargo run --example merge_pdfs -- a.pdf b.pdf -o merged.pdf
pdfa_validate	Validate PDF/A-1b/2b/3b compliance, list violations	Rust	cargo run --example pdfa_validate -- ../sample.pdf
redact_text	Search-based redaction: find patterns and permanently remove them	Rust	cargo run --example redact_text -- in.pdf out.pdf PATTERN
wasm/index.html	Open a PDF and extract its text entirely in the browser via @pdfluent/sdk-wasm, no server, no upload	JavaScript (WASM)	Serve the repo root (python3 -m http.server), open /wasm/

How-to guide programs

The howto_* examples are the programs from the how-to guides on pdfluent.com, byte for byte; each guide page links here and embeds the video in which the same code is typed and run. Each one reads the input file named in its source, from the directory you run it in.

Example	What it shows	Language	How to run
howto_compress_pdf	Compress a PDF in Rust, the complete program from the guide, also shown in its video	Rust	cargo run --example howto_compress_pdf
howto_encrypt_pdf	Encrypt a PDF with a password in Rust, the complete program from the guide, also shown in its video	Rust	cargo run --example howto_encrypt_pdf
howto_extract_text_by_page	Extract text page by page from a PDF in Rust, the complete program from the guide, also shown in its video	Rust	cargo run --example howto_extract_text_by_page
howto_extract_text_pdf	Extract text from a PDF in Rust, the complete program from the guide, also shown in its video	Rust	cargo run --example howto_extract_text_pdf
howto_read_pdf_metadata	Read PDF metadata in Rust, the complete program from the guide, also shown in its video	Rust	cargo run --example howto_read_pdf_metadata
howto_write_pdf_metadata	Write PDF metadata in Rust, the complete program from the guide, also shown in its video	Rust	cargo run --example howto_write_pdf_metadata
howto_generate_pdf_thumbnails	Generate page thumbnails from a PDF in Rust, the complete program from the guide, also shown in its video	Rust	cargo run --example howto_generate_pdf_thumbnails
howto_get_pdf_page_count	Get the page count of a PDF in Rust, the complete program from the guide, also shown in its video	Rust	cargo run --example howto_get_pdf_page_count
howto_merge_pdfs	Merge PDFs in Rust, the complete program from the guide, also shown in its video	Rust	cargo run --example howto_merge_pdfs
howto_render_pdf_to_jpeg	Render PDF pages to JPEG images in Rust, the complete program from the guide, also shown in its video	Rust	cargo run --example howto_render_pdf_to_jpeg
howto_render_pdf_to_png	Render a PDF page to PNG in Rust, the complete program from the guide, also shown in its video	Rust	cargo run --example howto_render_pdf_to_png
howto_open_pdf_with_password	Open a password-protected PDF in Rust, the complete program from the guide, also shown in its video	Rust	cargo run --example howto_open_pdf_with_password
howto_fill_pdf_form	Fill PDF form fields in Rust, the complete program from the guide, also shown in its video	Rust	cargo run --example howto_fill_pdf_form

All examples run against sample.pdf, a small public test document bundled in this repo.

Licensing

The examples in this repository are licensed under the MIT licence (see LICENSE). The PDFluent SDK they call stays under AGPL-3.0 or a commercial licence, at your option. The AGPL is the default and the complete product: there is no licence key, no activation call and no tier, every feature works in every build, and nothing marks the output. If you cannot accept the copyleft obligation, the commercial licence is sold yearly and self-service in four options: Commercial (per organisation), OEM Startup and OEM (per product), and Priority support (an add-on). Security reports go to hello@pdfluent.com.
