About DawgToolz
A growing collection of free browser-based tools. No account. No uploads. No nonsense.
How this started
I build tools for myself.
Every time I run into something that should be quick and free but isn't, I just build it. Sign a PDF without uploading it somewhere sketchy. Convert a CSV to JSON without creating an account. Resize an image for Instagram without a watermark. I build it, I deploy it, I use it.
Over time that became a bunch of tools. At some point it felt silly to keep them to myself, so here they are. Nothing special. Just useful stuff I kept needing.

How it works
Every tool runs entirely in your browser. When you load a file it stays on your device. Nothing gets sent to a server, stored anywhere, or seen by anyone. This is possible thanks to modern browser APIs and libraries like pdf-lib, PDF.js, and the File API.
The map and route tools are the exception. They send GPS coordinates to third-party routing APIs to calculate roads and paths. No data is stored after the request completes.
Why free
Because the tools are cheap to run. There is no server processing files on every request, no storage costs, no infrastructure. The work happens on your device. The only real cost is hosting a static site. A few unobtrusive ads cover that. Nothing that pops up in your face or blocks the tool from working.
