All tools

Every HandyTray tool in one place. They all work right in your browser — nothing to install, no account to create, and your files never leave your device.

QR codes

QR code scanner Read a QR code from an image, screenshot, or photo — or scan one live with your camera.

Images

HEIC to JPG converter Turn iPhone photos (HEIC) into JPG or PNG — several at once, zipped, right in your browser. WebP to JPG converter Convert WebP images to JPG or PNG (and back) — multiple files at once, no uploads. EXIF data viewer See what a photo reveals: date taken, camera, exposure, and the GPS location on a map. Photo metadata remover Strip EXIF data, GPS location, and other metadata from photos — with no quality loss.

Text

Morse code translator Translate English to Morse code and back — play it as audio or download a WAV file. Roman numeral converter Numbers to Roman numerals and back, dates in Roman numerals for tattoos, and a 1–100 chart.

Device tests

Mic test Check your microphone online — live sound wave and level, a too-quiet or too-loud warning, and playback. Reaction time test How fast do you react to green, a beep, or the F1 start lights? Average of 5 tries, ranks, and a leaderboard.

Developer tools

JSON formatter & validator Beautify, minify, and validate JSON — errors get an exact line and a plain-English fix, long IDs stay exact. JSON compare Compare two JSON files and see every added, removed, and changed value with its path — key order ignored. Base64 decode & encode Decode Base64 to text, images, or files and encode anything back — UTF-8 safe, JWT ready. UUID generator Random UUID v4 and GUID values, plus hex and Base64 secrets for developers.

Web & SEO

Open Graph checker Preview how a link will look on Facebook, WhatsApp, LinkedIn, or X — and test its og:image.
