Free batch tools for developers and designers

- supporters
Nine tools so far, all built around the same idea: batch processing instead of one-file-at-a-time. Highlights include a bulk image resize/convert/compress tool, a CSV to JSON converter with automatic encoding detection, a batch JWT decoder, a site crawler and audit tool, and a bulk IP/DNS/SSL lookup tool. No server upload, no account, and no cost โ everything runs client-side.
