100kb-sdk ⚡

Official B2B WebAssembly Client-Side Image, PDF & Biometric Media Optimization SDK

100kb-sdk is a zero-latency, client-side WebAssembly library for React, Next.js, Vue, Angular, Svelte, and TypeScript applications. It compresses user-uploaded images (JPEG, PNG, WebP, HEIC) and PDF documents to exact target file sizes (e.g. 50KB, 100KB, 200KB) 100% inside the user's browser GPU/RAM before uploading to AWS S3, Cloudflare R2, or Supabase Storage.

📦 Installation

npm install 100kb-sdk
# or
yarn add 100kb-sdk

💡 Quick Start Example (React / Next.js)

import { compressImage, compressPDF, createPassportPhoto, removeBackground } from '100kb-sdk';

// 1. Compress Image to 100KB ceiling in <20ms
const { blob: imageBlob, sizeBytes } = await compressImage(file, { 
  targetKB: 100, 
  mimeType: 'image/jpeg' 
});

// 2. Vector-Preserving PDF Compression
const { blob: pdfBlob } = await compressPDF(pdfFile, { targetKB: 200 });

// 3. ICAO Biometric Passport Photo Cropper (70% Head Ratio)
const { blob: passportBlob } = await createPassportPhoto(photoFile, { 
  country: 'us-visa', 
  targetKB: 50 
});

// 4. Studio AI Background Removal
const { blob: transparentPng } = await removeBackground(photoFile);

⚡ 1-Line AWS S3 / Cloudflare R2 Pre-Upload Hook

Save 85%+ on your cloud storage and bandwidth bills by compressing images on the user's device before upload:

// Wrap your upload handler: Automatically compresses files to <100KB
const preCompress = createS3UploadHandler({ targetKB: 100 });

async function handleFileUpload(file: File) {
  const optimizedBlob = await preCompress(file);
  
  // Upload optimizedBlob to AWS S3 / Cloudflare R2 / Supabase
  await uploadToS3(optimizedBlob);
}
