Zero uploads, ever
Every tool runs entirely in your browser using WebAssembly and modern browser APIs. There's no upload step โ it simply doesn't exist. Close the tab and every trace of your file is gone.
Built for India
Generic calculators don't know CGST vs IGST, old vs new tax regimes, PPF's 15-year lock-in, or TDS on FD interest. Ours do โ because that's what our users actually need to calculate.
Tested, not just shipped
Every tool is manually tested on Chrome, Firefox, Edge, and Safari before release โ and re-tested after every update.

Frequently asked questions
Are AWE-OS tools really free? What's the catch?
Most tools are completely free with no usage limits, no watermarks, and no signup. The site is supported by advertising, and a small number of advanced features (like AI-assisted tools) may require an account because they use paid AI services behind the scenes. Core PDF, calculator, and converter tools will stay free.
Do my files get uploaded to your servers?
No. Our file tools (PDF, image, CSV) process everything inside your browser using WebAssembly and browser file APIs. Your file never leaves your device โ you can verify this yourself by watching the Network tab in your browser's developer tools while using any tool. See our privacy policy for full details.
Do the tools work offline?
Many do. Once a browser-based tool has loaded, the processing needs no internet connection. Tools that fetch live data โ like the currency converter โ or that use AI need a connection to work.
Are the Indian tax and investment calculators up to date?
Yes. Tax slabs, GST rates, PPF interest rates, and similar figures are reviewed at every Union Budget and whenever rates change, and each calculator shows the financial year it applies to. If you spot an error, we correct it and log the correction on the affected page.
Is there a file size limit?
Because processing happens on your device, the practical limit is your device's memory rather than an arbitrary server cap. Most modern laptops handle PDFs of several hundred MB comfortably โ larger than most server-based free tools allow.
Who builds and maintains AWE-OS?
AWE-OS is built by a small independent team. Every tool is designed, tested, and maintained in-house, and every guide on the blog is written or reviewed by the team โ you can read more on our About page, including how we test tools and how the site is funded.
Can I request a new tool?
Yes โ and requests genuinely shape the roadmap. Several current tools, including the GST invoice generator, started as user requests. Contact us and we'll reply with whether and when it's planned.
How is my data handled by the AI tools?
AI tools (Resume Builder, Content Writer) are the exception to fully-local processing: your input text is sent to an AI provider to generate results, then discarded. We never use your content to train models, and we disclose exactly what's sent in each tool.
Built by a small team that got tired of "free" tools with catches
AWE-OS started with a simple frustration: every free PDF site wanted an upload, an email, or a subscription for the third file. Every EMI calculator was built for US mortgages. We believed everyday utilities should be genuinely free, genuinely private, and built for how people in India actually work.
Today AWE-OS offers 53 tools used by students, freelancers, and small businesses. We publish who we are, how tools are tested, how content is written and corrected, and how the site earns money โ because a tool you trust with your documents should have nothing to hide.
