Bandwidth Calculator
Convert data units and estimate transfer time, website traffic or average bandwidth with explicit reporting periods and allowance formats.
Base64 Encode / Decode
Encode UTF-8 text as Base64 or decode Base64 locally in the browser, without treating the encoded output as encryption.
IP Subnet Calculator
Calculate IPv4 or IPv6 subnet ranges from CIDR prefixes, or validate a contiguous IPv4 dotted mask and its address capacity.
Random Password Generator
Generate passwords locally with cryptographic randomness, chosen character classes and optional unique-character constraints.
URL Encode / Decode
Percent-encode or decode a UTF-8 URL component locally, keeping component encoding distinct from encrypting or validating a full URL.
Understanding digital units and encodings
Digital tools handle several different kinds of information. Bandwidth calculations relate a data amount to a transfer rate, subnet tools divide address space, and encoders change how text or bytes are represented. Select the input format before pasting a value, especially when bits, bytes, or character encodings are involved.
Encoding is not encryption, and validly decoded text is not automatically trustworthy. Network arithmetic describes an address or transfer model without testing a live network. Check each tool's supported format and limitations before using its output in a system configuration.
