DropFormat converts images, PDFs, and Word documents without uploading anything. The conversion happens in your browser using WebAssembly and local JavaScript libraries. The file you drop on the site stays on your computer.<\/p>\n
That sentence is also the whole pitch: most “free converters” send your photos to a server you have never heard of, then either keep a copy or claim they do not but cannot prove it. We removed the server from that loop.<\/p>\n
It is a property of the code, not a promise on a policy page. The converter is a JavaScript bundle that runs entirely in your browser tab. It decodes your file with local libraries such as libheif, LibRaw, pdf.js, pdf-lib, Mammoth, html2canvas, and the browser’s own native image decoder, encodes the output, and triggers a download. The network is not in that path. You can verify it yourself: open DevTools, switch to the Network tab, drop a file, watch nothing get sent.<\/p>\n
The one exception is error reports. If something goes wrong during conversion, the browser posts an error message and a stack trace to our server so we can fix the bug. The file’s bytes are never in that payload. The redacted filename, size, and MIME type are. That is the entire surface area of data we collect. The details are on the privacy policy<\/a>.<\/p>\nNeed another format?<\/h2>\n
