💡 Frequently Asked Questions (FAQ)
How does the online image compressor work?
Our image compression tool loads your image file into local browser memory, draws it onto an offscreen canvas at updated resolution scales, and converts it into compressed JPEG/WebP formats using specific quality values. Everything is processed locally in-browser with zero uploads.
Are my images or documents uploaded to a server?
No! All tools inside Arcade Hub's Utility Hub are 100% client-side. Processing occurs entirely in-memory on your local browser. Your data is never transmitted across the network, making it completely private and secure.
How do I scan a QR code from a saved image file?
Switch to the "Scan Image" sub-panel in the QR Code tab, drop or select your QR image file. The client-side parser scans the image pixel grid to find and decode the QR metadata directly, rendering the result text instantly without camera permissions.
How are word and character statistics calculated?
Our word counter scans the text input area, filters out punctuation marks, splits blocks by whitespace, and counts matches. Reading duration is estimated using a standard reading rate of 200 words per minute. The density parser counts repeating words to show top SEO search terms.
How is the Loan EMI amortization repayment computed?
Repayment is computed using standard loan amortization formulas: \[EMI = \frac{P \cdot r \cdot (1+r)^n}{(1+r)^n - 1}\] where \(P\) is the Principal loan amount, \(r\) is the monthly interest rate, and \(n\) is the duration in months.
How is my exact age calculated?
The age calculator compares the millisecond timestamp of your birth date to the current system clock time, breaking down the difference into years, months, and days, and computes the millisecond difference to the next annual birthday.
