Hey Product Hunt community! 👋
I built 100kb-sdk to solve a very common problem: user file uploads are massive, and cloud storage bills are expensive.
Modern smartphone cameras shoot 12MB to 15MB photos. When users upload these on web forms:
1. On Vercel / serverless architectures, uploads crash with "413: Payload Too Large" (Vercel has a hard 4.5MB limit).
2. On AWS S3 or Cloudflare R2, teams bleed money on storage and serverless resizing fees.
Instead of paying Cloudinary $99/mo or running backend workers, 100kb-sdk executes 100% inside the user's browser GPU/RAM via WebAssembly & Canvas. It compresses images (JPEG, PNG, WebP, HEIC) and deflates PDF vector streams down to exact target KB ceilings (e.g. 50KB, 100KB, 200KB) in ~25ms before upload.
Key Highlights:
• 0ms cloud server latency & 100% GDPR/HIPAA compliant (files never leave user RAM)
• Tree-shakeable for React, Next.js, Vue, and a 1-line Web Component (<100kb-uploader>)
• Exact target-KB bisection engine
• Free forever for open-source & personal projects, with an optional flat-rate $19/mo commercial license for unbranded white-label apps.
