Tools
Small browser utilities you can use right away.
Text Tools
Count characters and clean up text for everyday writing and pasting.
Character Count
Count total characters, characters without spaces, lines, words, and bytes for pasted text in one place. It works well for essays, profile text, contact forms, and social posts, and the text stays in your browser instead of being sent to a server.
Remove Line Breaks
Remove unwanted line breaks, replace them with spaces, or delete blank lines from text copied out of PDFs, emails, notes, and web pages. It helps turn broken text into readable paragraphs, and the pasted content is processed only in your browser.
Web
Handle URLs, QR codes, and login helpers for everyday web tasks.
QR Code Generator
Create QR codes from URLs or plain text, then adjust size, foreground color, background color, quiet zone, and error correction before downloading a PNG. It is useful for flyers, cards, posters, and web sharing, and everything runs locally in your browser.
URL Formatter
Complete, clean, encode, decode, sort query parameters, normalize trailing slashes, and remove tracking parameters from one or many URLs at once. It is designed for share-ready links and development checks, and it processes your input locally in the browser.
Password Generator
Generate secure random passwords in your browser with custom length, character types, presets, and copy-friendly output for one or many passwords at a time. Nothing is sent to a server, and generated values are not stored in cookies or shareable URLs.
Dates and Planning
Check deadlines, schedules, date differences, and business days.
Date Calculator
Calculate dates before or after a chosen day, measure the difference between two dates, and count business days while skipping weekends or Japanese public holidays from bundled data. It is useful for deadlines, contracts, travel planning, and quick schedule checks in the browser.
Age Calculator
Calculate full age from your date of birth in your browser, plus Japanese era names, a simple year-based zodiac animal, a star sign from month and day, child-style month counts under six, day-count milestones, days until a chosen adulthood age (18 or 20), and a multi-person table with copyable text. Nothing is sent to a server.
Western Year and Japanese Era Chart
Check Western years against Japanese era years across Reiwa, Heisei, Showa, Taisho, and Meiji in one quick reference chart. It is useful for forms, resumes, birth dates, and Japanese documents, and it also helps clarify transition years, first-year notation, and year-label lookups at a glance.
Age Chart
Quickly check ages by birth year for 2026, along with Japanese era labels and zodiac signs, in one readable chart. The displayed age is the age reached during 2026, so you subtract one before the birthday, and you can use the Age Calculator for an exact date-based result when you need more precision.
School Grade Chart
Pick a birth date and school year to estimate grade level and typical entrance and graduation years under Japan’s common April-start school-year rules. It is useful for school paperwork and quick checks, while intentionally excluding regional differences, repeat years, gap years, and non-Japanese systems or other exceptional paths.
Image Creation
Light image tasks such as resizing.
Money Calculators
Calculate tax, discounts, salary, savings, subscriptions, and splitting bills.
Tax-Included / Tax-Excluded Calculator
Calculate tax-inclusive prices, tax-exclusive prices, and tax amounts in either direction, with support for common tax rates and selectable rounding rules. It is helpful for quotes, shopping checks, invoices, and expense review when you need a quick browser-based estimate.
Discount Calculator
Calculate discounted prices, savings, discount rates, and reverse values for percentage discounts, fixed-amount discounts, and stacked offers. It also supports tax-inclusive or tax-exclusive views and rounding choices, making sale and coupon comparisons easier.
Hourly Wage Calculator
Estimate daily pay from hourly wage, work hours, breaks, overtime, late-night premiums, and commute pay, then extend the result into monthly and annual income estimates. It is useful for part-time work planning, shift comparison, and rough paycheck checks in the browser.
Monthly Salary / Annual Income Converter
Convert monthly salary, annual income, hourly wage, daily pay, and weekly pay into comparable gross income estimates, with optional bonus settings. It helps with job-offer comparison, income planning, and translating part-time pay into monthly or yearly figures.
Subscription Annual Cost Calculator
Convert subscription costs into yearly, monthly, and daily equivalents, track multiple services together, and review the longer-term cost of recurring payments. It is useful for trimming fixed expenses, checking cancellation candidates, and understanding how recurring services add up over time.
Savings Goal Calculator
Calculate how long it takes to reach a savings goal from your current amount, target amount, start date, deadline, and planned savings pace. It helps with travel funds, emergency savings, and purchase planning, and the numbers stay in your browser rather than being sent elsewhere.
Bill Split Calculator
Split a total amount by the number of people, adjust rounding by units such as 10, 100, or 500, and see how the rounding difference should be handled. It also supports organizer adjustments and uneven shares, making restaurant, trip, and event settlements easier.
