Why we're the Blue Cow 🐄
Purple Cow means remarkable. Ours is blue — because blue means tools, trust, and tech. We built ToolHerd because people were wasting time switching between 10 different sites just to crop an image, make a PDF, or convert a file. Every tool here is free, fast, and runs in your browser. Your files never leave your device.
