I built 50+ free browser tools that run without uploads, servers, or accounts

I spent the last few months building NexaTools — a suite of 50+ browser-based tools that do everything from converting images to generating PDFs, testing regex, and transferring files between devices.

The key constraint: most tools never send your data to a server.

Why I built this

I kept using online file converters that required uploading files to unknown servers. For sensitive documents, screenshots, or anything with metadata — that's a problem.
