About

Tiny tools for everyday file headaches.

Kodotools is a growing collection of free, browser-based utilities for image tasks, passport photos, loan calculators, QR codes, and CVs. No uploads, no signups, no tracking — just simple tools that respect your time and your privacy.

The problem

Most online file tools are bloated, ad-heavy, and quietly upload your files to someone else's servers. They make you sign up, throttle you behind a paywall, or stamp watermarks on free output. For something as simple as compressing a photo for a job application, that's overkill.

Worse: when you're uploading a passport photo, an ID document, or a personal screenshot, you usually have no idea where that file ends up — or how long it stays there.

Our approach

Every Kodotools utility follows the same rules:

  1. Runs entirely in your browser. Your file is processed on your device using JavaScript. Nothing is uploaded, logged, or stored anywhere.
  2. Does one job, well. Each tool focuses on a single, specific task — like compressing an image to an exact KB target — and aims to be the best at that one thing.
  3. Free and unlimited. No accounts, no usage caps, no watermarks. Use it for as many files as you need.

What's in the toolkit

We're starting small and adding tools one at a time. Here's what's available now and what's on the way:

  • LIVE Image Compressor — shrink JPG, PNG, WebP, or HEIC photos to a precise KB size for forms with strict limits.
  • LIVE Image Resizer — resize, crop, or fit images for social platforms, forms, and profile photos.
  • LIVE Passport Photo Maker — crop passport photos with country, size, and custom pixel presets, use guide bands, adjust background fill, and export JPG.
  • LIVE Finance Calculators — calculate loan payments, EMI, auto loan payments, car payments, total interest, and amortization schedules with clean PDF reports and Excel exports. Also try the EMI calculator, auto loan calculator, car payment calculator, and amortization calculator.
  • LIVE Image Converter — convert JPG, PNG, WebP, HEIC, SVG, BMP, AVIF, GIF, and TIFF in your browser with batch downloads.
  • LIVE QR Code Generator — create QR codes for links, WiFi, WhatsApp, vCards, PDFs, locations, and more.
  • LIVE CV Maker — build a free, ATS-friendly resume with live preview, custom social links, and instant PDF download. No signup, no watermark.
  • SOON PDF tools — PDF conversion, compression, and document helpers.
  • SOON PDF to Excel — extract tables from PDFs into spreadsheets.

Finance tools, same privacy rule

The loan calculator, EMI calculator, and amortization calculator follow the same browser-first approach as the file tools. You can estimate payments, compare interest, add extra payments, print a polished PDF report, or export an Excel workbook with the full schedule.

Finance results are estimates for planning only, not financial advice. We include inputs, assumptions, notes, rounded values, and the full month-by-month schedule so the export is useful outside the page too.

What's free, what's funded

Every tool is free for everyone, forever. We make money from non-intrusive Google AdSense ads on the page — that's it. We don't sell data, because we never collect any in the first place.
