How to Parse a URL Into Its Components
Enter address text, submit it, and review the returned scheme, host, path, query, fragment, port, and related fields. The parser examines supplied text without retrieving the referenced resource, so the result concerns structure rather than destination content.
-
How to Extract URLs from Text
Paste text containing lowercase HTTP or HTTPS URL-like matches, choose how repeated matches should be handled, and run the extraction. The result provides the found matches and their total, subject to the tool’s matching boundary.
-
How to URL-Encode Text for a Query Parameter
Enter nonempty text, choose standard or query-style encoding, optionally list characters to preserve, and run the tool. The result is encoded text for URL use, not a validation of a complete URL.
-
How to Decode Percent-Encoded URL Text
Paste the percent-encoded text into URL Decode and run it to obtain decoded text. Then inspect the second-pass indication to learn whether decoding the first result changed it again.
-
How to Construct URLs from Components
Enter the address components, review the assembled result, and inspect the structured query information. The tool constructs and parses your entries, but it does not determine whether the resulting address can be reached.
-
How to Calculate Price per Unit
Enter a price, quantity, and unit label, then submit the calculation. The tool returns a formatted price per that unit, applying its input defaults and normalization rules.
-
How to use Unicode Inspector to inspect text
Enter text to inspect each processed character, its code-point details, UTF-8 bytes, and broad category label. Unicode Inspector also reports the processed-character count and combined UTF-8 byte total.
-
How to Generate One or More ULIDs
Enter an optional count, run the generator, and review the returned ULID strings. The default is one identifier, and the applied count is constrained to the range of 1 through 100.
-
How to Test Your Typing Speed and Accuracy
Enter reference text, a non-empty typed passage, and elapsed time in seconds, then run the calculation. You receive character-based typing speed, character accuracy, and an accuracy-adjusted speed.

How to Generate Twitter Card Meta Tags
Enter a non-empty title, add optional card details when needed, and generate the HTML Twitter Card meta-tag markup. The card type starts as `summary_large_image`, while an empty title produces no markup or metadata entries.
-
How to Format a Short Post and Check Its Character Count
Enter optional post text and comma-separated hashtags, then review the generated character count, remaining capacity, and validity. The tool applies a 280-character threshold to the resulting text.

How to Use a Triangle Calculator for Sides, Angles, Area, and Perimeter
Enter the available numeric side or angle measurements, submit them, and review the returned triangle properties. Insufficient or invalid entries produce an error result instead of calculated values.
