How Convertburda works

Every tool above lives on its own page and does one job. Where possible, conversion happens entirely in your browser using JavaScript — the file never reaches our servers. A few tools (clearly marked on their own page) process files on the server briefly, in memory, and discard them immediately afterwards. Either way, nothing is stored.

Free tools stay free, supported by quiet, contextual advertising. A Pro tier (no ads, saved conversion history) is planned — see the "Pro" button in the header.
