• JSON Validator — Use this free JSON Validator to validate JSON online and check whether a payload is syntactically correct before it reaches your app, API, or config. It helps catch invalid JSON in request bodies, webhook payloads, config files, copied logs, exported data, and browser-copied snippets. Paste raw JSON to check it quickly and spot common problems such as trailing commas, missing double quotes, broken brackets, single quotes, or incomplete objects.
• JSON Minifier — Use this free JSON Minifier to compress JSON into a compact one-line format by removing spaces, indentation, and line breaks. It is useful when you need smaller payloads for transport, storage, embedding, logging, testing, or copy-pasting into systems that expect compact JSON. Paste valid JSON to minify it quickly without changing the underlying data structure.
• Base64 Encoder — Use this free Base64 Encoder to convert plain text into Base64 instantly. It is useful when working with API payloads, authentication headers, test strings, encoded data transfer, JSON fields, and developer debugging tasks. Paste readable text and get a Base64-encoded result that is easy to copy into scripts, requests, configs, or tools that expect encoded input.
• URL Encoder — Use this free URL Encoder to convert unsafe characters into percent-encoded text for URLs, query parameters, redirects, and request values. It is useful when preparing links, encoding spaces and symbols, building tracking URLs, debugging API calls, and making sure special characters are transmitted safely inside web addresses. Paste text or a full URL to encode it instantly in the browser.
• URL Decoder — Use this free URL Decoder to convert percent-encoded URL text back into readable form. It is useful for inspecting query parameters, debugging redirects, reading encoded API request values, checking tracking links, and understanding what an encoded URL or parameter actually contains. Paste encoded text or a full encoded URL to decode it instantly in the browser.

Network Tools

IP, DNS, ping, port, and other networking tools.

• IP Lookup — Use this IP lookup tool to inspect basic information about an IP address directly in the browser. It is useful for checking whether an address looks valid, reviewing IP-related details during troubleshooting, and quickly inspecting an IP before using it in networking, DNS, or connectivity work.
• DNS Lookup — Use this free DNS Lookup tool to check DNS records for a domain, including common records such as A, AAAA, MX, TXT, NS, and CNAME when available. It is useful for troubleshooting domain resolution, checking whether DNS changes propagated correctly, reviewing mail and nameserver setup, and understanding how a domain is configured before making infrastructure or hosting changes.
• Ping Test — Use this ping test tool to check whether a host appears reachable and to estimate basic response time. It is useful when troubleshooting connectivity, comparing host responsiveness, or checking whether a device or site responds before moving on to DNS or port-related checks.
• Port Checker — Use this port checker to test whether a target host is listening on a specific port. It is useful for troubleshooting service availability, confirming whether a firewall may be blocking access, checking whether an app is exposed on the expected port, and verifying connectivity to common TCP services.
• IPv4 Validator — Use this IPv4 validator to quickly test whether an address matches valid IPv4 format and range rules. It is useful for network configs, scripts, forms, debugging, documentation, and any workflow where an invalid IP address can cause errors or wasted troubleshooting time.
• IPv6 Validator — Use this IPv6 validator to test whether an address matches valid IPv6 structure. It is useful for modern network configs, scripts, forms, troubleshooting, and documentation where compressed hexadecimal IPv6 syntax can be harder to verify manually than IPv4.

Text Tools

Word count, line count, text cleanup, text converters, and other text tools.

• Word Counter — Use this free Word Counter to count words, characters, characters without spaces, and lines instantly. It is useful for essays, blog posts, article drafts, meta descriptions, social captions, forms with text limits, and general content editing. Paste any text to get a fast length overview and understand whether your writing fits the target limit before publishing, submitting, or reusing it elsewhere.
• Character Counter — Use this free Character Counter to check total character count instantly, including both characters with spaces and characters without spaces. It is useful for social media captions, meta descriptions, titles, form fields, SMS drafts, UI copy, product descriptions, and any text where exact length matters more than word count. Paste your text to measure it quickly before publishing, submitting, or reusing it elsewhere.
• Remove Extra Spaces — Use this tool to remove extra spaces from text and make copied content cleaner and easier to reuse. It is useful for text pasted from PDFs, websites, spreadsheets, emails, or documents where repeated spaces make the content harder to read or process.
• Text Case Converter — Use this text case converter to quickly change how text is capitalized. It is useful for headings, content cleanup, code-related text handling, CMS entry work, and rewriting copied text that is all uppercase, all lowercase, or inconsistently formatted.
• Text Reverser — Use this text reverser to flip text character by character in a single step. It is useful for fun text transformations, quick formatting experiments, puzzle-style text work, testing string handling, and any case where you want to see the input written in reverse order.
• Lowercase Converter — Use this lowercase converter to change uppercase or mixed-case text into lowercase instantly. It is useful for content cleanup, normalization, CMS work, copy editing, and any task where text should follow a consistent lowercase style.

Converters

Timestamp, bytes, and other simple online converters.

View all converters

• Timestamp Converter — Use this timestamp converter to turn Unix epoch values into readable date and time output. It is useful for logs, APIs, databases, developer tools, and debugging workflows where raw numeric timestamps need to be understood as actual calendar dates.
• Bytes to MB Converter — Use this bytes to MB converter to turn raw byte values into readable megabytes. It is useful when checking file sizes, storage limits, upload restrictions, API responses, logs, or technical data where bytes are too large to read comfortably in raw form.
• Bytes to KB Converter — Use this bytes to KB converter to turn raw byte values into readable kilobytes. It is useful for file sizes, upload limits, logs, storage metrics, API responses, and technical data where a raw byte count is too small or awkward to read directly.
• KB to MB Converter — Use this KB to MB converter to turn kilobyte values into more readable megabytes. It is useful for file sizes, storage checks, upload limits, exports, and any technical workflow where KB values are easier to compare once converted into MB.
• HEX to RGB — Use this HEX to RGB converter to turn hex color codes such as #FF5733 into RGB values. It is useful for CSS editing, design handoff, theme work, UI styling, and any workflow where a color must be translated from hex notation into red, green, and blue values.
• RGB to HEX — Use this RGB to HEX converter to turn red, green, and blue values into a hex color code. It is useful for CSS styling, UI design, theme work, color matching, and any workflow where an RGB color must become a web-friendly hex value.
