How to Create Multi-Page TIFF Files in Node.js (Without ImageMagick)

#webdev #javascript #node #npm

If you've ever tried to create a multi-page TIFF in Node.js, you know the pain. Most solutions require ImageMagick as a system dependency, which is a headache in Docker, serverless environments, or CI pipelines. Others wrap native binaries with brittle child_processcalls.

I ran into this exact problem while building a document processing pipeline — I needed to merge multiple scanned images into a single multi-page TIFF programmatically, with no external system dependencies.

After digging through the options, I ended up writing a pure Node.js solution and published it as an npm package: multi-page-tiff.

The Problem

Multi-page TIFF files store multiple images as linked Image File Directories (IFDs) inside a single .tiff file. Creating one correctly means writing the TIFF binary structure yourself — most image libraries only handle reading, not writing multi-page TIFFs.

Common workarounds people try:

ImageMagick via child_process— works but requires ImageMagick installed, breaks in serverless
sharp — great library but doesn't support writing multi-page TIFFs
tiff-multipage — last published 3 years ago, minimal maintenance
tiff-to-png — converts TIFF to PNG, not the other way

The Solution

npm install multi-page-tiff

const { createMultiPageTiff } = require('multi-page-tiff');
const fs = require('fs');

const images = [
  fs.readFileSync('./page1.png'),
  fs.readFileSync('./page2.png'),
  fs.readFileSync('./page3.png'),
];

const tiffBuffer = await createMultiPageTiff(images);
fs.writeFileSync('./output.tiff', tiffBuffer);

That's it. No native binaries, no system dependencies. Works on AWS Lambda, Vercel, Docker, Windows — anywhere Node.js runs.

Use Cases
Multi-page TIFFs are common in:

Fax systems — fax files are almost always multi-page TIFFs
Document scanning — scanners output multi-page TIFFs
Medical imaging — DICOM-adjacent workflows often use TIFF
Legal/archival — PDF alternatives for scanned documents
Insurance and banking — document submission pipelines

Why Not Just Use PDF?
TIFF is lossless, supports higher bit depths (16-bit, 32-bit), and is required in many enterprise, government, and medical workflows where PDF is not accepted. If your system specification says TIFF, there's usually no substitute.
