About ConvertKind

ConvertKind is a collection of small, focused converters for images, PDFs, video, data, text and units. Every tool runs entirely in your web browser using JavaScript, so your files are never uploaded to a server.

We use well-known open-source libraries — heic2any (HEIC), ag-psd (PSD), pdf.js and pdf-lib (PDF), lamejs (MP3), gifenc (GIF), js-yaml (YAML), UPNG.js + pako (PNG) — plus the Canvas and Web Audio APIs built into your browser. JPG-to-PDF, ICO and ZIP files are written by our own small, dependency-free code.
