Most online converters make you upload your files to someone else's server. That's slow, and it means trusting a stranger with your photos, spreadsheets and documents. Every tool on TidyKit runs in your web browser instead, so your files are processed on your own device and never uploaded.
Skipping the upload also makes the tools fast, and there's no server imposing a file-size limit or asking you to sign up. Once a page has loaded, most tools keep working even if you go offline.
