About iToolMania
Built and operated by AdMatrix Media
iToolMania is 43 file and utility tools that run in a browser tab. There is no signup, no watermark, and no upload queue. It is built and operated by AdMatrix Media, a marketing agency founded by Narender Chaudhary, which also runs Job Result India.
Why the tools run on your device
Every tool here does its work inside your browser. Your file is read into your own device's memory, processed by engines the browser already ships, and handed straight back to you.
This is not a marketing angle bolted on afterwards; it decided the architecture. Every large competitor makes you upload the document first. That is a reasonable thing to accept for a holiday photo and an unreasonable thing to accept for a contract, a bank statement, a passport scan or a medical letter, which is exactly what people convert most. If the file never leaves your machine, there is no copy to leak, no retention policy to read, and nothing to hand over on request.
You can check this rather than believe it. Open your browser's developer tools, switch to the Network tab, and run any conversion: no request carries your file.
What we will not pretend
Running everything client-side has real costs, and we would rather say them than have you find out.
- Some tools are not possible this way. High-quality OCR and PDF-to-Word need serious processing. If we ever ship those, they will run on a server, that page will say so plainly, and this claim will not be made for them.
- Large files depend on your device. There is no server to offload to, so a 300-page PDF is limited by your own memory.
- We are not the biggest. 43tools, not 500. Everything listed works; nothing is a “coming soon” placeholder.
How the site makes money
The free tools cost us almost nothing to run precisely because your device does the work, so they can stay free without a catch. Paid plans exist for the things that genuinely cost money: batch work, very large files, and any future server-side tool. See pricing.
We do not sell your data. There is nothing to sell: your files never reach us, and the only thing an account stores is an email, a password hash, your plan, and a daily usage count. The privacy policy spells it out.
How the tools are built
The conversions use the browser's own canvas and crypto APIs plus established open-source libraries: pdf.js for reading PDFs, pdf-lib for writing them, JSZip for bundling multi-page output. Unit conversions use exact factors rather than rounded ones, which is why one stone comes out as exactly 14 pounds. Temperature uses proper offset maths rather than a scale factor, so −40 °C correctly equals −40 °F.
12 tools carry a written guide explaining the format trade-offs, because the useful thing is usually knowing whether to convert, not just how.
