GST, EMI, word counting, age & date math, QR codes and resumes, plus SEO, Google Ads and social media ad tools for marketers. 100% free, no signup, no ads on the tools 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, put together a resume that actually gets past applicant tracking software, preview your Google snippet, write a search ad, or resize an image for an Instagram ad, 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. A UPI Link Generator tab gives you shareable GPay, PhonePe, and Paytm links too. Download the QR 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.
Preview exactly how your page will look in Google on desktop and mobile, with pixel-accurate title and description truncation. Generate meta and Open Graph tags, JSON-LD schema markup, a robots.txt file (with AI-crawler blocking), and clean URL slugs.
Write responsive search ads with live character counters, a Google-style preview and an ad checklist, then export them to Google Ads Editor. Format keywords into match types, mix keyword lists, grab starter negative keyword lists, plan budget and break-even ROAS, and tag URLs with ValueTrack UTMs.
