Open the toolFree tools
Small utilities we built for our own work and left open for everyone. They run entirely in your browser — nothing is uploaded, nothing is stored, and they keep working offline. No sign-up, no limits, no catch. That matters most for the invoice generator and the image compressor: your customers' details and your photographs never leave your device.
Invoice generator
Make a proper invoice and download the PDF in seconds.
Open the toolImage compressor and resizer
Make photos smaller without uploading them anywhere.
Open the toolJSON formatter and repair
Format, validate and repair JSON that almost parses.
Open the toolWhy we give these away
We built every one of them for our own work. Keeping them private would have saved us nothing, and putting them behind a sign-up form would only have made them worse.
They run entirely in your browser. Nothing you type, paste or drop in is uploaded, stored or logged — which matters when the file is a passport scan, when the invoice carries your customer's address and tax number, or when the JSON you are debugging holds API keys. Turn off your connection and they all still work.
Need something bigger built?
These are small things we made in an afternoon. The rest of the site is what we do when a business needs software that has to work.
