## Working with files

Most PDF operations accept file contents as a binary:

```elixir
alias NativeElixirPdfUtilities.Info

with {:ok, pdf} <- File.read("report.pdf") do
  Info.page_count(pdf)
end
```

HTML rendering and text extraction also provide file helpers. Each task guide
shows the relevant function and its return value.

## Inspecting PDF syntax

For access to individual PDF objects, use the [PDF reader](pdf-reader.md).
For raw syntax tokens and byte positions, use the [tokenizer](pdf-tokenizer.md).
Neither is needed for the common tasks above.

See [Licenses](licenses.md) for the project and bundled-data notices, and the
