Client-side WebAssembly SDK for compressing images and PDFs in the browser before upload
Ahrefs Domain Rating set in type 2 Nov 2026, reset 1 Nov 2026.
A WebAssembly SDK that compresses images and PDFs locally in the browser, reducing AWS S3 storage costs by 85% while ensuring full GDPR and HIPAA compliance.
100KB Developer is a client-side WebAssembly SDK that enables developers to integrate image and PDF compression directly into their applications. Files are processed entirely in the browser using local RAM or GPU, with no server involvement, ensuring zero latency and complete privacy compliance.
The SDK includes 18+ media and document processing tools: target KB bisection for precise file sizing, vector-preserving PDF optimization, ICAO biometric passport photo cropping, AI background removal, and batch processing via WebWorkers. It works with React, Next.js, Vue, Node.js, WordPress, and Shopify.
Developers can use the SDK free with a "Powered by 100KB" backlink, or purchase a Commercial License ($19/month or $149/year) to remove branding and unlock domain whitelisting and high-precision biometric features. All files are processed 100% locally, with no data retention or server uploads, making it GDPR and HIPAA compliant for handling sensitive documents like passports, medical records, and government forms.
Developer Free: $0/forever with unlimited client-side WASM engine, zero-config, target KB file bisection, and default "Powered by 100KB" backlink. Commercial License: $19/month (or $149/year, save 35%) for 100% unbranded license, automated domain whitelist lock, and high-precision biometric passport
