Useful shouldn't be complicated.

A good tool solves a small problem and gets out of your way. That's the idea behind ToolSprinkle.

Made for the work between the work

Formatting a bit of JSON. Resizing an image. Checking a color combination. We bring everyday utilities into one clear, colorful workspace — without accounts, advertising or subscriptions.

Local by design

Every current tool processes input in your browser. Your documents, text, images and generated passwords aren't uploaded to us. Tool preferences and saved-tool names can stay on your device, but your inputs do not.

Honest about the details

Each tool explains its limitations. Calculations include their assumptions. We don't promise that a contrast score makes an entire website accessible, or that a compressed image is always smaller.

How we check our tools

We test known examples, invalid input and browser interactions. JSON numeric tokens are preserved without floating-point rounding; CSV fields stay strings. Image results are decoded from the actual exported file before previewing. Tests help catch errors, but do not replace checking important results yourself.

Latest improvements · 14 October 2026

Stricter calendar validation, faithful JavaScript regex flags, clearer stale results and large-text feedback, better mobile discovery and CSV delimiter options.
