The RuntimeZero Philosophy

The web is full of tools that ask you to sign up, hand over your email, pay a subscription, or — worst of all — silently upload your private files to servers you know nothing about. We built RuntimeHub to be the opposite of that.

Every tool in the RuntimeHub ecosystem processes your data locally, on your device. No accounts, no passwords, no privacy policies that hide what really happens to your files.

Sketchy is a direct expression of that commitment. Fast, private, free — and nothing else getting in the way.

Images in. Vectors out.

Sketchy converts photographs, logos, scanned drawings, and screenshots into SVG — the format that scales infinitely without losing quality. Whether you need a crisp icon at 16px or a print-ready graphic at 10,000px, the output holds.

You control the result through four parameters: how many colours, how much detail, how large a region to keep, and how much smoothing to apply before conversion. The tool adapts to your input rather than forcing you to adapt to it.

Everything happens in your browser. Close the tab and it's gone — no history, no cloud storage, no trace.

Made by RuntimeZero

Sketchy is part of RuntimeHub — a growing library of free tools built and maintained by RuntimeZero, an independent developer studio focused on doing more with less: no servers, no subscriptions, no unnecessary complexity.

The suite spans image tools, audio utilities, document processors, and data tools. All free, all private, all running entirely in the browser.

No server-side processing — ever
No tracking on your files or conversions

How we build things

Every RuntimeHub tool is held to the same standard before it ships.

Private by default

Your files never leave your device. This is not a policy promise — it is how the tool is architected. There is no upload mechanism to disable or forget to secure.

Free, with no strings

No freemium limits, no watermarks, no account walls. RuntimeHub tools are funded by unobtrusive ads — not by your data or your attention.

Fast and lightweight

No heavy frameworks, no unnecessary dependencies. Pages load fast, tools start instantly, and your device does the work — not our infrastructure.
