FreeToolDev
Free batch tools for devs & designers — no upload, no signup, runs in your browser
FreeToolDev is a collection of free, browser-based batch utilities for developers and designers. Instead of processing files one at a time like most free tools, everything here handles multiple files or entries at once — batch image resize/convert/compress, CSV to JSON, QR code generation, JWT decoding, and more. Nothing is uploaded to a server; all processing happens locally in your browser. No account required, completely free.
