This is a growing collection of simple, practical utilities for developers, photographers, and anyone who spends time working with data. Every tool on this list runs entirely in your browser. Nothing is uploaded, nothing is tracked, and you will never be asked to create an account or start a free trial to copy a result.
Tools in this collection:
Whitespace Remover — Paste in messy text and strip it clean. Remove leading spaces, trailing spaces, extra spaces, blank lines, or flatten everything into a single readable format. The Clean & Readable mode is the one you’ll use most — it trims every line and adds consistent spacing so your text pastes nicely anywhere.
JSON Formatter — Paste raw or minified JSON and get it back pretty-printed with full syntax highlighting. Minify mode squashes it to a single line. Validate mode tells you instantly whether your JSON is valid and shows the exact error if it isn’t.
EXIF Reader — Drop in any photo and read all the data your camera embedded at the moment of capture. Camera, lens, shutter speed, aperture, ISO, focal length, date and time, GPS coordinates, and reverse-geocoded location. Your photo never leaves your computer.
UUID Generator — Generate one UUID or a hundred in a single click. Version 4 (random) or Version 1 (time-based), uppercase or lowercase, with or without hyphens. Uses cryptographically secure randomness built into your browser.
Hash Calculator & Validator — Compute MD5, SHA-1, SHA-256, SHA-384, or SHA-512 hashes from text or any file. Use the Validate tab to compare a computed hash against an expected checksum in one step — perfect for verifying downloads. Everything runs locally, nothing is ever uploaded.
List → CSV Converter — Paste in any list and convert it to CSV instantly. One item per line, space-separated numbers, tab-delimited, pipe-separated — pick your input format, pick your output separator, and the result updates as you type. Trim whitespace, remove duplicates, sort alphabetically, control how many items appear per row, and prefix every row with a command or argument for terminal use. Download as a .csv file or copy straight to your clipboard.
QR Code Generator — Generate a QR code for any URL, block of text, WiFi credentials, email address, SMS message, or contact card. Adjust the size, error correction level, foreground and background colors, and quiet zone margin. Download as PNG or SVG. Everything generates locally in your browser — no server, no account, no watermark.
