What is Base64 decoding?

Base64 decoding is the process of translating a Base64-encoded ASCII string back into its original binary representation or readable text format. It takes groups of four 6-bit characters and reconstructs the original 8-bit bytes.

How do I decode Base64 to readable text?

Paste your Base64 string into the input box. The tool automatically processes the string in real time, converting encoded characters into UTF-8 text or binary content.

Can I decode Base64 online for free?

Yes. This online Base64 decoder runs directly inside any modern web browser without requiring software installations, subscriptions, or account creation.

Is my data uploaded to an external server?

No. All encoding and decoding operations execute strictly client-side within your browser using JavaScript Web APIs. Your input strings and converted files are never transmitted to any external server or stored anywhere.

What is the difference between Base64 and Base64URL?

Standard Base64 uses '+' and '/' characters with optional '=' padding, which can conflict with URL query strings. Base64URL replaces '+' with '-' and '/' with '_', and omits trailing '=' padding for safe web tokens and JWTs.

How to Calculate Tip: Easy Formula & Steps

Calculating a tip manually is straightforward. Simply multiply your pre-tax bill amount by your desired tip percentage expressed as a decimal:

Tip Amount = Bill Amount × (Tip Percentage ÷ 100)
Total Amount = Bill Amount + Tip Amount

Mental Math Trick for 15% & 20%:

To calculate 20%: Move the decimal point one place to the left to find 10%, then double that number. (e.g. For a $64 bill, 10% is $6.40; double is $12.80).
To calculate 15%: Find 10% by moving the decimal point one place left, divide that in half to get 5%, and add the two numbers together. (e.g. On a $60 bill, 10% is $6.00 and 5% is $3.00, totaling $9.00).

How to Split a Restaurant Bill Fairly

Dining out with friends should be relaxing, not a math headache. When splitting a bill:

Equal Split: Ideal when everyone ordered approximately similar mains and drinks. Divide the grand total (including tip) equally.
Itemized Split: If one person had expensive wine or multiple courses while another had an appetizer, calculate each diner’s base cost and apply an equal 18%–20% tip factor to their portion.
One Payer + Transfers: Have one person pay on their card and others reimburse them via Venmo, Zelle, or Cash App immediately using the calculated per-person numbers above.

Tip Calculator FAQs

Clear, concise answers to common questions about Base64 decoding, encoding, and specifications.

To calculate a tip, multiply the bill total by the tip percentage divided by 100. For example, for a $50 bill with an 18% tip: $50 × 0.18 = $9.00 tip. The total amount to pay would be $50 + $9 = $59.00.
