About Heptiq
Heptiq is an independent suite of web utilities for AI engineers, software developers, university students, and business professionals—engineered so the files and text you enter are processed in your browser.
Who Operates Heptiq
Heptiq (`heptiq.com`) is founded, engineered, and maintained by Sabir Anwar (Heptiq Engineering). Every calculator, data formatter, and technical reference guide is built with verifiable mathematical formulas and cited official sources.
Whenever a tool uses external pricing data—such as OpenAI, Anthropic, or Google Gemini API token rates, or PayPal and Stripe merchant processing fees—we link directly to the provider's official pricing documentation and display the exact date the rates were verified.
In-Browser File & Text Processing
Files and text you enter into our calculators, JSON formatters, PDF splitters/mergers (`pdf-lib`), and image tools are processed locally in your browser memory. Note that the AI Background Remover downloads an open-source ONNX vision model to your browser cache on first use.
Audited Formulas & Rates
Every calculator displays the mathematical equation and assumptions it uses, alongside a worked example that matches the tool's live output.
How We Are Funded
To keep all 107 tools free without account registration or usage paywalls, Heptiq is supported by lightweight, non-intrusive display advertisements via Google AdSense. Read our Privacy Policy for cookie and opt-out details.
