What is this?

@doko/react-native-pdf-editor is a React Native library for creating, editing, rendering, encrypting, and digitally signing PDF files on iOS and Android.

It is built as a New Architecture-only Nitro Module and uses a modified PoDoFo fork for the core PDF model. iOS binds directly to the C++ core. Android uses Kotlin bindings over the published podofo-android JNI wrapper. The result is an API that feels like React Native, while the heavy PDF work happens natively, where it belongs.

This is not a PDF viewer component; it does not render a scrollable PDF reader on screen. It is for manipulating PDF files: generating reports, merging documents, filling simple fields, adding annotations, rendering pages to images, protecting files with passwords, and signing with external keys.

What it can do

Area	Supported today
Documents	Create, open, save, merge, split/copy page ranges
Pages	Add, remove, rotate, resize, reorder
Drawing	Text, images, lines, rectangles, circles, colors, graphics state
Fonts	PDF standard 14 fonts, custom font files, in-memory font buffers
Images	Embed encoded image buffers and draw them on pages
Annotations	Create/read common annotation base data: type, rect, contents
Forms	Text boxes, checkboxes, field inspection
Metadata	Title, author, subject, creator
Encryption	AES-256 encryption, passwords, permissions, encryption inspection
Rendering	Render saved PDF pages to RGBA bitmap, write PNG/JPEG
Text extraction	Extract page text entries, optionally filtered by regex
Signing	Signer-agnostic PAdES B-B, B-T, B-LT, B-LTA
Verification	Check signature byte-range integrity, without trust-chain validation

What it is not

Not a PDF viewer UI.
Not a full PDF content parser that returns every text/image/vector element as structured JS objects.
Not a trust-store or certificate-revocation validation framework.
Not old-bridge compatible.

For viewing PDFs, pair it with a dedicated PDF viewer; this library is the toolbox for editing them.

Package entry points

import { PdfDocument, PdfRenderer } from '@doko/react-native-pdf-editor';
import { signPdf, createSigner } from '@doko/react-native-pdf-editor/signing';

Signing is intentionally exposed from a separate /signing entry point so apps that only edit or render PDFs do not need to import the signing helpers and types.

Status

The library is still alpha. The API is already useful, but some parts may change while the public shape is refined and Android/iOS parity continues to improve.
