About Tool Kart

Tool Kart is a collection of fast, free online utility tools built around one simple idea: the tools you use every day should respect your privacy. Everything here runs entirely in your browser, so the files and values you work with never leave your device.

Why we built it

Many "free online tools" upload your files to a server to process them. That is slower, and it means handing your data to someone else. We take a different approach: modern browsers are powerful enough to compress images, generate QR codes and run calculations locally. No upload, no account, no clutter.

What you can do here

• Image Compressor — Compress and resize JPG, PNG and WebP images right in your browser. No upload, fully private.
• QR Code Generator — Create QR codes from any text or URL and download them as PNG or SVG. Free and instant.
• Age Calculator — Find your exact age in years, months and days, plus days until your next birthday.
• EMI Calculator — Calculate loan EMI, total interest and amortization for home, car and personal loans.
• Unit Converter — Convert length, weight, temperature and area units instantly, including sq ft to sq m.
• GST Calculator — Add or remove GST at 3%, 5%, 12%, 18% or 28% and see the CGST/SGST split instantly.
• SIP Calculator — Estimate the maturity value and returns of a monthly SIP mutual-fund investment.
• Percentage Calculator — Work out X% of a number, what percent one number is of another, and percentage change.
• Word & Character Counter — Count words, characters, sentences and paragraphs with an estimated reading time.
• Password Generator — Create strong, random passwords in your browser with length and character options.

How we keep it free
