Why Quikkit instead of TinyPNG, iLovePDF or Smallpdf?
Most "free" online tools upload your files to their servers, cap you at a handful of files per day, and add watermarks or a signup wall. Quikkit runs entirely inside your browser using WebAssembly and the Canvas API. Your photos, contracts and data never leave your device – which also means no waiting for uploads and no limits on size or count.
Every tool is free. Our roadmap includes a Pro tier for batch automation and dynamic QR codes; the core tools will stay free forever.
