About UtilityKit

UtilityKit is a collection of free tools for text, developer workflows, data conversion, calculators, images, PDFs, and audio. Each page explains the inputs it accepts and the result it produces.

Many text, developer, calculator, generator, and media tools process input in the browser. Server-assisted tools, including Image Resizer, Image Compressor, and PDF Merge, upload selected files for processing. An upload picker alone does not tell you where processing happens: check the individual tool’s notice and limits before using sensitive data. Temporary processing files are cleaned up on a best-effort basis.

Paste-and-share has a different data path from one-shot browser tools. A plain paste is stored on the server until its expiry, while password-protected pastes are encrypted in the browser before upload. Use the expiry and security controls shown on that page.

Some pages request an external service, such as a public DNS resolver, or load a library from a CDN. The tool page identifies material external dependencies where they affect how input is processed.

UtilityKit uses Umami for aggregate page, referral, and interaction analytics. Tool inputs are not intentionally included in those events. Each tool has its own input limits and processing requirements; verify the downloaded or copied result before using it in another system.
