A free file converter that runs 100% in your browser. No uploads, no servers, no accounts. Your files never leave your device. 50+ format pairs across images (JPG, PNG, WebP, HEIC, AVIF, SVG, TIFF, ICO), data (CSV, JSON, XML, YAML, XLSX), and documents (PDF, DOCX, Markdown, HTML, TXT). All conversions happen client-side using the Canvas API, WebAssembly, and JavaScript libraries. Verify the privacy claim yourself: open DevTools, check Network tab while converting any file.
