Choose the right tool for the task
Use the five generation tools to create passwords, identifiers, fake identities, or synthetic test data. Use the four validation tools to inspect supplied IP addresses, URLs, UUIDs, or Base64 values. URL Encoder / Decoder transforms URL text, while Remove Non-Printable Characters cleans supported control characters from text.
- Password Generator and Random String Generator create configurable character strings.
- UUID Generator creates version 4 UUIDs. Fake Identity Generator creates country-based identity records.
- Random Data Generator creates values through separate tabs, including synthetic test data.
- IP Address Validator, URL Validator, UUID Validator, and Base64 Validator check supplied values.
Choose a generator when you need new fixture data. Choose a validator when you already have a value and need to inspect its format. A validation result does not prove that a destination, system, credential, or workflow is safe.
Generate passwords, identifiers, and test data
Open the generator that matches the output you need, set its visible controls, then use its copy or download action where available.
- Password Generator: Choose Random or Memorable. In Random mode, set Length from 6 to 128 and Count from 1 to 20, then select Uppercase (A-Z), Lowercase (a-z), Digits (0-9), Symbols (!@#$...), and Exclude ambiguous. In Memorable mode, set Words from 3 to 8, choose a Separator, set Count from 1 to 10, and optionally use Capitalise first letter or Append random number (0-99).
- UUID Generator: Enter a Count from 1 to 10,000. Select Lowercase, Uppercase, or Braces, then use Copy or Download. This generator creates RFC 4122 version 4 UUIDs only.
- Random String Generator: Set Length from 1 to 512 and Count from 1 to 1,000. Choose Uppercase letters, Digits, Symbols, and Exclude ambiguous chars, then use Copy or Download.
- Fake Identity Generator: Choose a country and quantity, generate the records, then use Copy All as JSON or Download JSON. This is separate from the synthetic test-data workflow.
- Random Data Generator: Choose the Password, String, Number, UUID, or Test Data tab. In Test Data, select fields, set Quantity from 1 to 1,000, optionally enter a Seed, choose JSON or CSV in Format, select Generate Test Data, and use Download. The result is synthetic test data, not a fake identity record.
Validate IPs, URLs, UUIDs, and Base64 values
Use a single-value tab for one check or a bulk tab for several values. For bulk input, enter one value per line or separate values with commas, then retrieve the CSV results with the available actions.
- IP Address Validator: Use Single IP or Multiple IPs. The multiple-input view accepts line-separated or comma-separated IP addresses and provides Copy CSV and Download CSV.
- URL Validator: Use Single URL or Multiple URLs. The single view shows validation status and a component breakdown. The multiple view accepts line-separated or comma-separated URLs and provides Copy CSV and Download CSV.
- UUID Validator: Use Single UUID or Multiple UUIDs. Bulk input accepts one UUID per line or comma-separated UUIDs, with Copy CSV and Download CSV. Single results include version, variant, structure, and timestamp information where applicable.
- Base64 Validator: Use Validate for one value or Bulk Validate for line-separated or comma-separated values. Use Copy CSV or Download CSV for bulk results. This tool validates and reports structure-related details; it does not expose a Decode control.
Encode, decode, or clean text
- URL Encoder / Decoder: Paste text into the input area, choose Auto-detect, Encode, or Decode, and use Copy or Download. Use Upload to load input or Magic Un-Mess to process URL tracking parameters supported by the tool.
- Remove Non-Printable Characters: Enter or upload text, review the output, and use Copy or Download. Use Keep tabs and Keep newlines to control whether those characters remain. The confirmed behavior concerns the tool's supported ASCII/control-character cleanup; it does not establish broad Unicode cleanup or deployment safety.
Use the tools with their confirmed limits
UUID generation here is version 4 only; it does not provide UUID versions v1 through v7. Reusing the same Seed, selected fields, and Quantity in Random Data Generator's Test Data workflow makes the generated result deterministic.
These interfaces generate, transform, clean, or check supplied values. They do not confirm that a password is suitable for a production secret, that a URL destination is safe, or that cleaned text is safe for database insertion or code deployment. The collection page also includes analytics and a separate subscription form; tool-processing behavior should not be treated as a claim about those page interactions.
Frequently asked questions
Which tool should I use for a UUID?
Use UUID Generator to create version 4 UUIDs, or UUID Validator to inspect supplied UUIDs in single or bulk mode.
Does the UUID Generator support versions other than version 4?
No. The linked generator creates RFC 4122 version 4 UUIDs and formats them as Lowercase, Uppercase, or Braces.
How do I validate multiple values?
Open the relevant bulk tab, enter one value per line or separate values with commas, then use Copy CSV or Download CSV where shown.
Can the Base64 Validator decode a value?
No Decode control is exposed. It validates Base64 input and reports structure-related details. Use a confirmed encoder/decoder tool when you need decoding.
What does the Random Data Generator Seed field do?
In the Test Data tab, reusing the same Seed, selected fields, and Quantity makes the generated result deterministic.
What do Keep tabs and Keep newlines control?
They control whether tab and newline characters are retained when Remove Non-Printable Characters processes the input.
