∞ Infyn

Fast, 100% free, and private in-browser utilities — zero server uploads.

Infyn is a modern, open-source web utility suite offering essential image and PDF tools that execute entirely in the user's browser. No subscriptions, no credit cards, no tracking ads, and your files never touch a remote server.

⚡ Core Philosophy

• 🔒 100% Client-Side Privacy (Zero Cloud Uploads): All image manipulation, AI segmentation, encryption/decryption, and PDF rendering run locally on your device via WebAssembly (WASM), Web Workers, and HTML5 Canvas.
• 🚫 100% Free & Ad-Free: No paywalls, no watermark additions on exports, no subscriptions, and no intrusive ads.
• 📦 Batch-First: Designed to handle multiple files in bulk with instant 1-click ZIP downloads.
• 🚀 Zero Friction: No login or signup required. Just open and use.

🛠️ Tools & Capabilities

📄 PDF Suite

• PDF Merger: Combine multiple PDFs into a single document with visual drag-and-drop reordering.
• PDF Splitter & Page Extractor: Visual page grid to extract specific pages into a new PDF or split into individual PDFs (ZIP download).
• PDF Password Protector: Secure confidential PDFs with standard AES-256 password encryption in browser.
• PDF Unlocker: Remove passwords and access restrictions from encrypted PDF documents safely.
• PDF to Image: Render and export all or selected pages into high-resolution JPG/PNG images.
• Image to PDF: Convert and combine images into clean, formatted PDF documents with custom margins and page sizes.

🖼️ Image Suite

• AI Background Remover: Automated transparent cutout generation using in-browser machine learning models.
• Batch Image Compressor: Reduce image file sizes drastically with custom percentage and target size controls.
• Image Resizer & Crop: Resize dimensions, change aspect ratios, and fit photos with blurred canvas padding.
• Universal Image Converter: Batch convert between JPG, PNG, WEBP, AVIF, and HEIC.
• HEIC to JPG Converter: Seamlessly decode Apple iPhone .heic/.heif photos into universally compatible JPEGs via WASM.
• EXIF & Metadata Remover: Strip GPS locations, camera serials, and device metadata from photos before sharing.

📦 NPM Package (infyn)

You can install Infyn directly into your React, Next.js, Vue, Vite, or Node web project to process PDFs and images locally with zero cloud API keys:

npm install infyn
# or
pnpm add infyn
# or
yarn add infyn

1. All-in-One Import

import { 
  mergePDFs, 
  splitPDF, 
  encryptPDF, 
  decryptPDF, 
  compressImage, 
  removeExif, 
  convertHeicToJpg 
} from "infyn";

2. Subpath Imports (Optimized for Tree-Shaking)

If you only need a specific domain, import directly from the subpath to keep your bundle minimal:

📄 PDF Utilities (infyn/pdf)

import { mergePDFs, extractPDFPages, splitPDF, encryptPDF, decryptPDF, isPDFEncrypted } from "infyn/pdf";

// Merge multiple PDF files into 1 document
const mergedBytes = await mergePDFs([file1, file2]);
const mergedBlob = new Blob([mergedBytes], { type: "application/pdf" });

// Extract specific pages (1-indexed: pages 1, 3, and 5)
const extractedBytes = await extractPDFPages(myPdfFile, [1, 3, 5]);

// Password-protect a PDF
const protectedBytes = await encryptPDF(myPdfFile, "mySecretPassword123");

// Unlock an encrypted PDF
const decryptedBytes = await decryptPDF(encryptedFile, "mySecretPassword123");

🖼️ Image Utilities (infyn/image)

import { compressImage, convertImage, convertHeicToJpg, removeExif } from "infyn/image";

// Compress an image with dimension & quality constraints
const result = await compressImage(photoFile, {
  quality: 0.75,
  maxWidth: 1920
});
console.log(`Compressed from ${result.originalSize} to ${result.compressedSize} bytes (Saved ${result.savedPercentage}%)`);

// Strip EXIF / GPS metadata
const cleanImageBlob = await removeExif(photoFile);

// Convert Apple HEIC to standard JPEG
const jpegBlob = await convertHeicToJpg(heicFile);

// Convert between formats (PNG -> WebP)
const webpBlob = await convertImage(pngFile, "image/webp", 0.85);
