The tools are organized into four categories: text for writing and document analysis, audio for converting between WAV, MP3, OGG, and AAC, video for converting between MP4, WebM, AVI, and MOV, and developer for encoding, decoding, and converting between JSON, XML, YAML, CSV, and TSV. Each category includes several focused tools. Below you will find a detailed overview of the main features in each area.
Text Tools
Our text tools help writers, students, and content creators work faster. Count words and characters, compare two versions of a document, analyze word frequency for SEO, or convert text case. All processing happens locally - paste your text and get instant results.
📝 Word Counter
The Word Counter counts words, characters, sentences, and paragraphs in real time. It also estimates reading time at 250 words per minute, shows readability grade using the Flesch formula, and displays character limits for Instagram, Twitter, LinkedIn, and meta descriptions. Students use it to hit essay word limits. Content writers use it to plan article length and optimize for SEO. Social media managers use it to stay within platform limits. No signup required - paste or type and watch the stats update as you edit.
🔄 Text Diff
The Text Diff tool compares two text blocks side by side and highlights exactly what changed. Use it for proofreading drafts, reviewing code or config changes, comparing contract versions, or spotting edits in any document. Paste the original and the modified version - the tool shows additions and deletions clearly. No file upload needed. Works with any length of text.
📊 Word Frequency Analyzer
The Word Frequency Analyzer shows which words appear most often in your text. Useful for SEO - identify overused keywords or find gaps in your vocabulary. Writers use it to spot repetitive phrasing. Researchers use it to analyze corpus patterns. Paste your text and get a sorted list of word counts. Helps you diversify your writing and improve clarity.
🔤 Case Converter
The Case Converter converts text to UPPERCASE, lowercase, Title Case, or sentence case. Fix accidentally caps-locked text, format headings consistently, or prepare text for APIs that expect a specific case. One click and the conversion is done. Handles large blocks of text.
Audio Tools
Convert audio files between WAV, MP3, OGG, AAC, and MP4. Musicians, podcasters, and content creators use these tools to prepare audio for sharing, editing, or playback.
🎵 WAV to MP3
The WAV to MP3 converter transforms uncompressed WAV audio into MP3 format. WAV files are large and lossless - ideal for editing but impractical for sharing. MP3 reduces file size by up to 90% while keeping sound quality suitable for music, podcasts, and voice. Export stems from your DAW as WAV, convert to MP3 for sharing demos or uploading to platforms. No desktop software needed.
🎧 MP3 to WAV
The MP3 to WAV converter does the reverse - converts MP3 back to uncompressed WAV. Use it when you need lossless audio for editing in a DAW, for archival, or for compatibility with legacy software. The output is standard WAV format, ready for professional use.
🎬 MP4 to MP3
The MP4 to MP3 converter extracts audio from video files. Have an MP4 with music or a voiceover? Get the audio as MP3 in seconds. Perfect for saving music from videos, extracting podcast audio from video recordings, or reducing file size when you only need the sound. Upload, convert, download.
🔊 MP3 to OGG
The MP3 to OGG converter converts MP3 to OGG Vorbis format. OGG offers better compression and quality at similar bitrates. It is open-source and widely supported in browsers and media players. Use it for web audio, game assets, or when you prefer an open format over MP3.
Video Tools
Convert video files between MP4, WebM, AVI, and MOV. No account needed. Works on desktop and mobile. Video creators, marketers, and anyone handling video files use these tools to ensure compatibility across devices and platforms.
📹 MP4 to WebM
The MP4 to WebM converter transforms MP4 video into WebM format. WebM uses VP8 or VP9 codecs and offers efficient compression with broad browser support. Use it when you need video for web playback - many sites and players handle WebM natively. Smaller file sizes and good quality make it ideal for embedding video on websites.
🎞️ MP4 to AVI
The MP4 to AVI converter converts MP4 to AVI format. AVI is widely supported by legacy software and older editing applications. If you need to open a video in an older program that does not support MP4, or if you are working with systems that expect AVI, this tool handles the conversion without installing extra software.
🔄 AVI to MP4
The AVI to MP4 converter transforms AVI files into MP4. MP4 is the standard for sharing and streaming - smaller file size, universal compatibility. Have old AVI footage from a camera or legacy export? Convert it to MP4 for easy sharing, uploading to social media, or streaming.
📱 MOV to MP4
The MOV to MP4 converter converts Apple MOV files to MP4. iPhone and Mac record in MOV by default. Many players and platforms prefer MP4. Convert your recordings to MP4 so they play on any device - Windows, Android, smart TVs, and more. No quality loss, just format change.
Developer Tools
Encode and decode Base64, convert between JSON, XML, YAML, CSV, and TSV, and format or minify HTML and JSON. All tools run client-side for maximum privacy. Developers, DevOps engineers, and data workers use these utilities daily for debugging, integration, and data transformation.
🔐 Base64 Encoder and Decoder
The Base64 Encoder converts plain text to Base64. The Base64 Decoder converts Base64 back to text. Use them for data URIs, API payloads, encoding binary data in text format, or debugging encoded strings. Paste and convert - no external service involved. Your data never leaves your browser.
📋 JSON Formatter
The JSON Formatter beautifies and validates JSON. Add indentation and line breaks for readability. Catch syntax errors before they cause problems in production. Paste minified JSON from an API response and get human-readable output. Also use it to minify JSON - remove whitespace for smaller payloads.
🔄 JSON to XML Converter
The JSON to XML converter transforms JSON data into XML format. Integrate with legacy systems that expect XML. Create config files. Transform API responses. We also offer XML to JSON, JSON to YAML, YAML to JSON, and conversions between CSV and TSV. All run in your browser - no server round-trip.
📊 Format Converters
Beyond JSON and XML, we support conversions between YAML, CSV, and TSV. Need to turn a spreadsheet export into JSON? Use CSV to JSON. Need to convert a config file from YAML to XML? We have that too. HTML prettifier and minifier round out the set for front-end work. Every conversion is instant and client-side.
