Free tools · no server
Tools that run on your device
Every tool here works in the browser tab you already have. Nothing is uploaded, nothing is stored on a server, and most of them keep working with the network switched off. That is not a gimmick — it is the same way we build the software we sell.
Pick one
App development cost calculator
Platform and features in, a rupee range out — from the band we already publish, with a shareable link to your own estimate.
EMI calculator
Monthly EMI, total interest and what a little extra each month saves you — with a yearly schedule and CSV export.
Developer toolbox
JSON to TypeScript, JWT decode, cron, regex, diff, base64, hashing and UUIDs — eight tools that never send your input anywhere.
Image toolkit
Compress to an exact KB ceiling, resize, convert to WebP and strip camera metadata — entirely in the tab.
Token estimator
How many tokens is that prompt, and what will it cost? Paste the text, set your provider's rates, get dollars and rupees before you send anything.
JPG to PDF
Combine photos and scans into one PDF — any order, A4 or Letter, no watermark, no upload.
Why these are built this way
No upload.Your inputs never leave the tab. There is no API behind these tools, which is also why they cannot be slow or rate-limited.
No account.No email wall, no trial, no "unlock the full result". You get the whole answer the first time.
Works offline.Static pages with the logic in the browser. Load once, keep working on a train.
Honest numbers.Every range is anchored to something we already publish or a stated assumption — never a made-up precise figure.
