CapyConvert

I got tired of using third-party file converters that charge $10/month for something that costs fractions of a penny to run locally.

So I built CapyConvert. Upload a file, pick a format, convert. No sign-up, no ads, no installs. Conversions run client-side when possible, so your files never leave your machine.

I made it free with a tipping option. I use it more than anyone else, probably weekly, for converting images, documents, and media files.
