UnitMaster.io
Hey everyone! π
I'm Tanmay, a solo developer. Like many of you, I'm tired of needing a monthly subscription just to do simple tasks like removing an image background or converting files.
In this era where everyone is slapping an "AI Tax" on basic utilities, I spent my weekends building UnitMaster to give these tools away for free.
What I built:
The Features: Privacy-first Image Tools (Remove BG, Passport Photo), Engineering-grade Unit Converters, and Financial Calculators.
The Promise: No signups, no paywalls, no data uploads (everything runs locally in your browser).
My Goal: To create the "Wikipedia of Utilities" β a polished, premium-feeling place where the tools just work, without the greed.
I need your help: I just launched on Product Hunt! If you believe in free, quality tools, I'd appreciate your support: π https://www.producthunt.com/products/unitmaster?utm_source=other&utm_medium=social
I take feedback very seriously (I literally pivot features based on Reddit comments). Let me know what you think!

π Launch Announcement: UnitMaster 2.0
Title: UnitMaster 2.0 - The Privacy-First Digital Swiss Army Knife
Hey Hunters / Everyone! π
I'm Tanmay, the maker behind UnitMaster.
Today I am pushing a massive update that transforms UnitMaster from a simple converter into a complete Digital Utility Belt for professionals, developers, and creators.
π‘ The Problem
We all have those 10 tabs open: one for converting PDF to JPG, one for formatting JSON, another for downloading a YouTube thumbnail, and a calculator for our taxes. Most of these sites are riddled with spammy ads, feel like they were built in 1999, and worst of allβthey upload your private data to their servers just to process it.
π‘οΈ My Promise: Privacy is Non-Negotiable
I am dead serious about this: Your data should never leave your device unless absolutely necessary. With UnitMaster, I have spent countless hours re-engineering standard tools to run 100% Client-Side using WebAssembly and advanced browser APIs.
PDF Tools? Processed locally. Your contracts never touch my cloud.
JWT Debugger? Decoded in your browser. Your secrets stay secret.
JSON Formatter? Validated right here, on your machine.
β¨ What's New in 2.0?
I didn't just want it to be safe; I wanted it to be beautiful. I've poured my heart into the UI to make it feel like a premium, native app.
1. Developer Utility Belt π οΈ Everything a dev needs in a pinch, without the data risk.
JWT Debugger: Inspect tokens securely.
JSON Validator: Beautify and minify code.
Base64 Converter: UTF-8 safe encoding.
QR Code Generator: High-res, customizable.
2. Creator Studio π¬ A new home for content creators.
Thumbnail Grabber: Get MaxRes thumbnails from any YouTube video instantly.
3. The Classics (Upgraded) π
PDF Workshop: Merge, Split, Compress, Sign.
Image Studio: Crop, Resize, Remove Background.
Financial Suite: ROI, Mortgage, and Tax calculators that actually look good.
π The Vision
I am building the last bookmark you will ever need. One clean, fast, privacy-focused interface for every digital task.
I would love your feedback. Does the "Glass" UI feel responsive? Are there tools you're dying to see added?
Let's build the best utility site on the web.
