Process images and generate PDFs in the browser. Save thousands in cloud costs.

A blazing-fast, browser-native document and media processing engine written in pure Rust with a minimal dependency philosophy. All processing happens on the client's device — no server, no cloud costs, no data ever leaves the browser.

Quick Start (Browser / WASM)

npm install tpt-wasmforge

import { WasmForge } from 'tpt-wasmforge';

const forge = await WasmForge.init();

// Resize an image
const file = document.getElementById('file-input').files[0];
const image = await forge.loadImage(file);
const resized = image.resize(800, 600);
const blob = await resized.toBlob('image/jpeg', 0.9);

// Generate a PDF
const pdf = forge.createPdf();
pdf.addPage(595, 842); // A4
pdf.addText('Invoice #12345', { x: 50, y: 750, fontSize: 24 });
const pdfBlob = await pdf.toBlob();

Quick Start (Python)

pip install tpt-wasmforge

from tpt_wasmforge import WasmForge

forge = WasmForge()
image = forge.load_image("input.png")
image.resize(800, 600).save("output.jpg", quality=90)
