Useful tools, with the processing boundaries explained

What the site is for

The goal is to make common one-off tasks approachable: reorganize a PDF, resize a photo, inspect JSON, count words, generate a password, or create a first AI-assisted draft. Every tool page describes its current workflow, practical features, tips, known limits, and processing boundary.

The guide library connects related tools into practical workflows and favors verification steps over claims that an automated result is automatically correct.

This site does not publish claims of professional credentials, independent expert review, certification, a staffed support team, or a business address. Questions and corrections use the contact form described below.

Local by default is not universal

Many file operations run in the browser, including PDF organization, image compression and resizing, Base64 utilities, hashing, and password generation. Some features have a different boundary. AI tools send submitted content or extracted text through the RizzKit API to an external model provider, background removal uses RizzKit server processing, and Secret Share sends encrypted ciphertext for temporary storage. The relevant tool page explains the actual behavior.

Editorial principles

Documentation is checked against the current implementation and focused automated checks where available, not planned features. Meaningful limits and processing boundaries are stated where relevant. Code checks and reproducible examples do not replace independent legal, financial, security, accessibility, or subject-matter review.

Corrections and product feedback can be stored through the contact form. Submissions are feedback records, not a live-support channel, and a reply is not guaranteed. Privacy depends on the feature used; read its disclosure and the Privacy Policy before submitting sensitive material.
