PiPic is an image compression toolkit for people and AI agents. It offers a free browser app for PNG, JPEG, WebP, and AVIF, plus a CLI and HTTP API for scripts, CI pipelines, and agent workflows. The browser preserves the input format, supports batch downloads, and does not store uploaded images long-term. PiPic is built with Next.js, TypeScript, Hono, and Cloudflare Workers.
