Compress PDF files to reduce size while preserving readability. Placeholder — full compression needs pdf-lib WASM integration (coming soon).

Convert any browser-decodable audio format (MP3, M4A, OGG, FLAC, AAC, OPUS, WEBM) to universal 16-bit PCM WAV. Works with every audio editor and DAW.

Concatenate multiple audio files into one continuous WAV. Reorder tracks before merging, drop in MP3/OGG/WAV/FLAC/M4A. 100% browser-based.

Cut the start and end of any audio file in your browser. Millisecond precision, supports MP3, WAV, OGG, FLAC, M4A. Nothing uploads.

Convert MP3 (or M4A, OGG, FLAC, AAC, OPUS) to uncompressed 16-bit PCM WAV. Decode and re-encode happen entirely in your browser — audio never uploads.

Paste a shortened link (TinyURL, bit.ly, t.co, buff.ly, etc.) and see the full redirect chain + final destination before you click. SSRF-protected server-side fetch.

Remove EXIF, GPS, camera info, and all other metadata from images before sharing. Re-encodes images in your browser using the canvas API — the file never leaves your device.

Convert TOML configuration files to JSON instantly. Supports tables, nested tables, arrays, inline tables, arrays of tables, strings, numbers, booleans, and ISO datetimes. 100% browser-based.

Lint your Dockerfile against production best practices. Catches insecure defaults (root user, :latest tags), wasteful patterns, and missing directives (HEALTHCHECK, USER, WORKDIR) with a 0-100 quality score.

Parse .env files, catch syntax errors before deploy, and export to JSON, YAML, or shell exports. Auto-detects and masks sensitive keys (API keys, tokens, passwords).

Generate memorable passphrases using random dictionary words — 4-8 word combinations that are easy to remember but hard to crack.

Calculate perceived brightness (luminance) of any color — determine if text should be black or white on a given background for optimal readability.

Minify JavaScript code by removing whitespace, comments, and unnecessary characters — reduce file size for faster page loads.

Convert HTML markup to clean Markdown — headings, links, lists, bold, italic, code blocks all converted automatically.

Convert JSON objects to YAML format instantly — paste JSON and get clean, indented YAML output ready for config files and Docker Compose.

Generate CSS filter effects (blur, brightness, contrast, grayscale, hue-rotate, sepia) with sliders and live preview.

Create CSS text-shadow effects visually — adjust horizontal offset, vertical offset, blur radius, and color with live preview.

Generate SHA-512 cryptographic hash — 128-character hex output, the strongest standard hash function for maximum collision resistance.

Convert text to hexadecimal encoding and back — see every character as its hex code for debugging network protocols and binary data.

Encode and decode text using the ROT13 substitution cipher — each letter shifts 13 positions. Apply twice to get the original.

Strip all HTML tags from text and extract only readable content — clean text from web pages, emails, and CMS output.

Remove extra spaces, tabs, trailing whitespace, and blank lines from messy text — clean up text copied from PDFs and emails.

Reverse text character by character or word by word — useful for palindrome checking, encoding, and puzzle games.

Remove duplicate lines from text while preserving order — works with CSV data, log files, and any line-based text.
