I built this tool hub after noticing most "free tool" sites bury you in ads, watermarks, or forced sign-ups just to compress an image or format some JSON. Everything here runs client-side in the browser — nothing gets uploaded to a server, so it's fast and private. Started with image/PDF tools and kept adding SEO, dev, and business calculators as I needed them myself for client projects. Would love feedback on what tools to add next!
