SwiftConvert is a free, privacy-first file converter. Unlike most online converters, it does not upload your files anywhere — every conversion runs directly in your browser, so your files stay on your device.
Convert between image formats (PNG, JPG, WebP, GIF, BMP, AVIF, HEIC, SVG, TIFF, ICO), turn images and documents into PDF, extract images from PDFs, and convert spreadsheets and data between Excel, CSV, TSV and JSON — all for free, with no sign-up and no watermark.
Running conversions locally means there's no upload wait, no server storing your files, and no privacy trade-off. It's faster and safer than sending your documents to someone else's server.
