CACHEPLEX — FREE DIGITAL MARKETING TOOLS FOR EVERY WEBSITE OWNER

CachePlex is a set of free web tools that run in your browser without a signup wall in front of them. Favicon and app icon generators, image conversion and compression, QR codes, JSON and YAML validators, HTML, CSS and JavaScript minifiers, robots.txt and sitemap checkers, SSL and schema validators, meta tag generation and more. The pitch is straightforward: these are jobs you need doing repeatedly, and none of them should require an account, a subscription or a credit card to try. Most run entirely client side, so your files are processed in the browser and never uploaded anywhere. Each tool sits alongside a written guide covering how it works, the mistakes people make, and the technical detail behind it. The HTML minifier page explains why editing minified output breaks things and how protected blocks are handled, which is the sort of thing most tool sites leave out. Paid tiers exist for the heavier AI tools, priced pay as you go from $0.99 with a free daily allowance. No subscription required.
