Built differently from other converters
Genuinely private
Most "online" converters upload your file to a server. LocalConvert processes everything on your own device — there is no server to upload to.
No waiting on uploads
Skip the upload queue entirely. Conversion starts the moment you drop the file, at the speed of your own hardware.
Free, no catch
No signup, no watermark, no daily limits, no "pro" upsell blocking basic conversion.
