PDFium & Wazero

This project uses the PDFium C++ library by Google (https://pdfium.googlesource.com/pdfium/) to process the PDF documents.

We use a Webassembly version of PDFium that is compiled with Emscripten and runs in the Wazero Go runtime.

Getting started

From binary

Download the binary from the latest release for your platform and save it as pdfium.

You can also use the install tool for this:

sudo install pdfium-webassembly-linux-x64 /usr/local/bin/pdfium
Release types

The following release types are available:

  • Linux
    • WebAssembly (amd64 + arm64)
    • Native (amd64)
    • Native + MUSL (amd64)
  • MacOS
    • WebAssembly (amd64 + arm64)
    • Native (amd64 + arm64)
  • Windows
    • WebAssembly (amd64)
    • Native (amd64)

WebAssembly: this is a single binary that includes everything that you need to run pdfium-cli, but is a lot slower than native due to the WebAssembly runtime. Most useful if speed is not a concern and easy distribution is more important.

Native: A native build that requires pdfium and libjpeg-turbo to be available on your system.

Native + MUSL: Same as native but built with MUSL so that it does not require a system libc which allows it to be used in Alpine Docker containers.

From source

Make sure you have a working Go development environment.

Clone the repository:

git clone https://github.com/klippa-app/pdfium-cli.git

Move into the directory:

cd pdfium-cli

Run the command:

go run main.go

Or to compile and run pdfium-cli:

go build -o pdfium main.go
./pdfium -h

Output:

pdfium-cli is a CLI tool that allows you to use pdfium from the CLI

  pdfium [command]

  attachments Extract the attachments of a PDF
  completion  Generate the autocompletion script for the specified shell

The following build tags are available to control different build types:

  • pdfium_cli_use_cgo: whether to compile the native CGO version (faster, but requires pdfium to be installed).
  • pdfium_experimental: whether to enable experimental features of pdfium in the build.
  • pdfium_use_turbojpeg: whether to enable libjpeg-turbo support, which speeds up jpeg compression a lot compared to the default jpeg encoding in Go.
