About Kritools
Free, fast, browser-based utilities for developers, writers, students, and anyone who just needs to get something done — with no account, no uploads, and no paywall.
What Kritools is
Kritools is a collection of small, focused web tools that solve specific everyday problems. Need to format a broken JSON response from an API? Convert a PNG to WebP? Generate a Wi-Fi QR code for your café? Count the words in a draft before submitting it? Each of those tasks has a dedicated tool here — and none of them require you to install software, create an account, or hand your data over to a server.
Everything on Kritools is designed around three principles: speed (tools open instantly, no loading spinners), privacy (processing happens on your own device), and accessibility (no sign-up walls, no paywalls, no "free trial" tricks).
What you'll find here
Kritools currently covers four main categories:
- Developer tools — JSON formatter & validator, Base64 encoder/decoder, UUID v4 generator.
- Image tools — convert between PNG, JPG, and WebP, or combine images into a single PDF.
- Text tools — a live word and character counter with reading time and keyword density.
- Productivity tools — password generator, date calculator, and QR code studio for URLs, Wi-Fi, UPI, contacts, and email.
Each tool is built to solve its problem cleanly. Where a bigger or more complex product would get in the way, we deliberately keep things simple.
Why Kritools is free
Kritools is supported by lightweight, non-intrusive advertising — the same way most free web tools are funded. There are no premium tiers, no features locked behind a subscription, and no "rate limits" that push you toward an upgrade. Every tool you see today works the same for every visitor.
Who builds Kritools
Kritools is built and maintained by a small team that got tired of watching useful online tools get buried behind logins, ads, and upsells. We build tools we use ourselves, keep them minimal, and fix things when users tell us they're broken. If you spot a bug or have an idea for a tool that would fit here, we'd genuinely like to hear about it.
Privacy and security
Because Kritools processes data locally in your browser, the privacy model is simple: your content stays with you. We don't ask for your name, email, or payment details to use any tool. Preferences like dark mode and recently used tools are stored in your browser's own storage — you can clear them at any time through your browser settings.

Frequently asked questions
Is Kritools really free to use?
Yes — every tool on the site is free, with no sign-up required, no premium tiers, and no usage caps. Kritools is funded through lightweight advertising rather than subscriptions.
Do I need an account to use the tools?
No. There is no account system at all. You can use every tool anonymously, and your preferences (like dark mode) are stored locally in your own browser.
Where does my data go when I use a tool?
Nowhere. Wherever technically possible, tools process your input locally in your browser. Files, text, and passwords are never uploaded to a Kritools server.
