Images and spreadsheet data never leave your browser. Image conversion uses <canvas>, and CSV / TSV / XLSX / JSON / XML are parsed and rewritten in JavaScript — no upload, no server, no copy on disk. Excel files included: an XLSX is a zip of XML, and it is unpacked and rebuilt in the page using the browser's own compression support. HEIC included too: it is decoded in the page by a bundled WebAssembly decoder, because no browser but Safari can read HEIC on its own. If your browser cannot run that decoder — and any current one can — a HEIC is sent to the server to be decoded there instead, deleted the moment it is, and you are told it happened. Office documents do go to the server, where LibreOffice converts them; the upload is type-checked, stored outside the web root under a name we generate, and deleted as soon as the conversion finishes. The converted file is kept for 15 minutes so you can download it, then swept. Uploads are capped at 50 MB.
