IrisTool is a free, privacy-first collection of text, developer, image, SEO tools and calculators. Every tool runs entirely on your device — this site has no backend and no database, so nothing you type or upload is ever saved or sent anywhere.
Built for people who work with words, code, pixels and numbers.
Writers & Editors
Count, clean, restructure and polish any copy in seconds — from word counts and reading time to duplicate removal and case conversion.
Developers & Engineers
Format, validate, minify, encode and decode without leaving your tab. JSON, XML, JWT, Base64, hashes, regex, cron — the daily toolkit, instant.
Designers & Creatives
Resize, convert and compress images on-device, pick colors from anything, generate gradients and palettes — no uploads to unknown servers.
Marketers & SEO Specialists
Generate meta tags, schemas, sitemaps and UTM links, preview SERP snippets and social cards, and audit keyword density — a full SEO bench.
Students & Everyone Else
GPA and grade math, loans and tips, unit conversions, random pickers, dice, QR codes — practical utilities for everyday decisions.
Nothing you type here ever leaves this page.
IrisTool has no database and no backend — literally. Every tool is plain JavaScript running inside your browser tab. There is nothing to hack, nothing to leak and nothing to delete, because we never receive your data in the first place. Close the tab and it's gone.

Is IrisTool really free?
Yes. All 278 tools are free with no signup, no usage limits and no premium tier. There are no servers to pay for per request, so there is nothing to charge you for.
Is my data safe here?
Completely. The site has no backend and no database — every tool runs entirely in your browser. Text you paste and images you open are never transmitted, logged or stored anywhere.
Do I need to create an account?
No account, no email, no tracking cookies. Open any tool and use it immediately — that's the whole idea.
Does it work offline?
Once the page has loaded, most tools keep working offline because all the logic runs locally in your browser.
