Why use FreeTools?
Unlike many online utilities, FreeTools processes your files in the browser using modern Web APIs and WASM libraries. That means faster results on your machine, no waiting for uploads, and a clear privacy story: we never see your documents or photos. No account is required — open the page, drop a file, download the result.
