GST, EMI, word counting, age & date math, QR codes, and resume building — six tools, 100% free, no signup, no ads on the calculators themselves. Everything runs in your browser.
Most "free" tools online cap something — a daily limit, a watermark, a signup wall three clicks in. The tools on this page do not. Each one below started as a focused calculator or generator, built to be genuinely complete rather than a teaser for a paid version. Whether you need to work out GST on an invoice, compare loan offers, tidy up a block of text, generate a UPI payment QR, or put together a resume that actually gets past applicant tracking software, jump to the section below and use it directly — no account, no export limit, no catch.
Add or remove GST on any amount with an automatic CGST/SGST/IGST split, then generate a GST-compliant tax invoice or quotation with your logo, or look up the GST rate for a product or service by HSN/SAC code.
Work out your monthly EMI for a home, personal, or car loan, see how much a prepayment saves you, compare offers from up to four lenders side by side, and project SIP, lumpsum, FD, RD, and PPF returns.
Count words, characters, sentences, and reading time as you type, check your text against every major platform character limit, convert between Title Case and snake_case, clean up messy text, and find your most repeated keywords.
Calculate exact age in years, months, and days as of any date, find the gap between two dates in days and weeks, or add and subtract days, weeks, months, and years from a date — with leap years and month lengths handled correctly.
Generate a scannable QR code for any text, URL, WiFi network, or contact card, or build a UPI payment QR with a fixed amount and note so customers can pay by scanning. Download the result as a PNG.
Build a single-column resume — contact details, summary, work experience, education, and skills — formatted specifically to parse correctly through applicant tracking systems, then print it or save it as a PDF.
