The small jobs that come up when you run your own thing. All of them run entirely in your browser — nothing is uploaded, nothing is saved, and there is no account.

Getting paid

VAT threshold checkerTwelve months of turnover in, and where you stand against the £90,000 rolling test.
Day rate calculatorThe turnover you want, worked back to the rate that gets you there.
UGC usage rights calculatorA forever buyout, beside the same work licensed and renewed while the ad keeps running.

Putting things out

QR code generatorA QR code for a link, text, email or phone. Download it as PNG or SVG.
Social media image sizesDimensions, ratios and safe areas for the platforms you actually post to.

Colour and contrast

Colour palette generatorOne colour in, a palette out — with the tints and shades you'll actually need.
Contrast checkerTwo colours in, the WCAG ratio out — with a live preview of the actual text.
Colour converterHEX, RGB, HSL and CMYK. Paste any one, get the other three.

These are calculators. Each one ends by naming the thing it can't do once you close the tab — that limit is real, and it is the same limit whether or not you ever sign up.
