A little less busywork.

littlekit.app is a growing collection of tools for the tasks between your tasks: cleaning a list, converting an image, combining documents. Each tool does one job, explains what it supports, and tells you where its limits are.

Built to stay out of your way

No account is needed, and every tool processes your input on your device. There are no daily quotas and no upload step. Practical size limits keep the browser responsive, and they are stated in each tool before you start.

Why local processing

Files and text often contain things you would rather not hand to a server: contracts, medical letters, customer lists, credentials. When the work happens in the browser, the file never leaves your machine. That is a privacy property first and a speed property second.

How tools are selected

Tools are added when they are genuinely useful without an account, can run within the browser's limits, and can describe their behavior honestly. Each one is verified against real inputs before it is published, including error and limit cases. When a format or feature is not supported, the tool says so instead of failing quietly.

Guides and page content

The guides explain the formats and problems behind the tools, so you can make an informed decision about format, ordering, and limits rather than guessing. Every tool page also explains what the tool does, how to use it, a worked example, and answers to common questions.

Editorial standards

• Worked examples on tool pages are produced by running the tool itself, so the numbers and outputs you read are the ones you will get.
• Limits are stated as they are enforced in the code: file sizes, page counts, supported formats, and what is not preserved.
• When a claim depends on outside rules, such as tax rates, accessibility thresholds, or file-format specifications, the page names the standard it follows and says where the tool stops.
• Pages are corrected when a tool changes or an error is reported. Each guide shows the date it was last updated.

Feedback

Bug reports and suggestions are welcome at [email protected] or through the contact page. Reports about a broken tool or an unclear limit are the most useful kind.
