General
Applies to every tool on AnyCalOnline.
Are AnyCalOnline's tools really free?

Is my data safe when I use these tools?

Are the results from these calculators 100% accurate?
Our tools use standard, well-established formulas and are built to be reliable for everyday use, but they're not a substitute for professional financial, medical, or legal advice.

Date & Time Tools
Days Between Dates · Age Calculator · Time Calculator · Time Zone Converter
Does the days between dates calculator count both dates?
By default it counts exclusively (a standard "days until" style count). Check the inclusive option if you want both the start and end date counted.
How is my age calculated down to the exact day?
The age calculator compares your birth date to today's date (or any target date) using calendar-aware math, so it correctly accounts for leap years and varying month lengths — not a flat 365-day estimate.
Can the time calculator subtract hours and minutes, not just add them?
Yes — you can add or subtract any combination of hours, minutes, and seconds from a starting time.
Does the time zone converter adjust for daylight saving time?
Yes, conversions automatically account for daylight saving time changes in each location, so the comparison stays accurate year-round.
Financial Tools
Currency Converter · Loan & EMI Calculator
How current are the exchange rates in the currency converter?
The converter uses live exchange rate data, so the conversion reflects current market rates rather than a fixed or outdated figure.
Does the loan/EMI calculator include interest?
Yes — enter your loan amount, interest rate, and term, and the calculator returns your monthly payment (EMI) along with total interest paid over the life of the loan.
Can I use the loan calculator for any type of loan?
Yes, it works for personal loans, auto loans, and similar fixed-rate, fixed-term loans. Mortgage-specific costs like property tax and insurance aren't included.
Files & Image Tools
Merge PDF · Compress Image · ResizeLab
Are my files uploaded to a server when I merge or compress them?
No — the PDF merger and image tools process your files directly in your browser. Your files are never uploaded to or stored on our servers.
Will compressing my image reduce its quality?
There's a quality-vs-size tradeoff, and the compressor lets you adjust the compression level so you can balance a smaller file size against visible quality loss.
What image formats does ResizeLab support?
ResizeLab works with common formats including JPG, PNG, and WebP, and lets you resize by exact dimensions or by percentage.
Is there a file size or page limit for merging PDFs?
The merger is designed for everyday use cases like combining a handful of documents; very large files or an unusually high page count may be slower to process since everything runs in your browser.
Utilities
Random Password Generator · QR Code Generator
How secure are the passwords from the generator?
Passwords are generated randomly in your browser using customizable length and character rules, and are never transmitted or stored anywhere.
Do QR codes generated on this site expire?
No — the QR codes are generated as static images that encode your data directly, so they don't expire or depend on our site staying online.
Can I customize the password generator's rules?
Yes, you can set the length and choose whether to include uppercase letters, numbers, and symbols.
Fitness & Health
Fitness Self-Assessment Quiz
Is the fitness quiz a substitute for a real fitness test?
No — it's a self-assessment tool, not a clinical or diagnostic test. For precise measurements like VO2 max or body composition, see a certified trainer or medical professional.
How is my fitness score calculated?
Each of the 10 answers is worth 1 to 4 points across cardio, strength, flexibility, and lifestyle habits, and your total score places you into one of four fitness tiers.
Can I retake the fitness quiz?
Yes — retaking it every 4 to 6 weeks is a good way to see whether your training and habits are actually moving your score.
