Tools
Handy tools you can use without logging in. What you type is processed in your browser and is mostly never sent to the server.
No matching tool.
Images, QR & fun
Image Tools
Shrink, crop and adjust photos, paint with a brush, stack images as layers, and remove location data (EXIF). Also makes favicon sets, picks key colors and converts to Base64. Files never leave your browser.
QR Code Generator
Turn a link, text, Wi‑Fi login or contact (vCard) into a QR code and download it as PNG or SVG. No login needed, and what you type is not stored.
Metronome & Tuner
A metronome (BPM, time signature, tap tempo) and a tuner that reads the pitch of a sound through the microphone (guitar, ukulele and more). Sound is processed only on this device — never recorded or sent.
Ladder & Random Picker
Enter names to pick winners, split teams, play the ladder game, spin a roulette, flip cards or arrange seats. Dice, coin and lotto numbers too. Names never leave your browser and randomness comes from Web Crypto.
Sketchpad
A hand-drawing tool with a pen, highlighter, line, rectangle and ellipse; an eraser that removes whole strokes; and undo. Save as PNG or SVG — your drawing is never uploaded.
Voice & Screen Recorder
Record your microphone, screen or webcam right in the browser and save the file. Video and audio are processed only inside this browser and never sent to a server.
Magnifier
Use your phone camera to read tiny print: zoom in, raise the contrast and freeze the picture to read slowly. The video never leaves your device.
Keyboard test
Press keys to check that each one works. Supports Windows and Mac layouts and shows how many keys you hold at once and their key codes. Nothing is sent to the server.
Apple Wallet pass
Make a membership-card style Apple Wallet pass (.pkpass) and download it right away. Open the file on an iPhone to add it to Wallet.
LED banner
Turn your phone into an LED sign — show big scrolling, static or blinking text. For airport pickups, concerts and shop notices. Your text never goes to a server.
Audio Trimmer
Open an audio file, see its waveform, cut a section, apply fades, gain, normalization and mono, then save it as a WAV. The audio never leaves your browser.
Device Check
Test your camera, microphone, left/right speakers, keyboard input, and screen dead pixels and refresh rate right in the browser. Video and audio are never saved or sent to a server.
QR & Barcode Scanner
Read QR codes and barcodes from your camera or a photo, with the content classified and warning signs flagged. You can also make barcodes. Video and photos are never sent to a server.
PDF Tools
Merge PDFs, delete, rotate and reorder pages, save PDF pages as images, or bundle images into a PDF. Files are processed only in this browser and never uploaded.
Photo Text Reader (OCR)
Turn the text in photos and screenshots (Korean and English) into text you can copy. Photos are never uploaded; everything runs in this browser.
Use offline too
When turned on, tool pages and the files they need are saved on this device so the calculation and conversion tools work without internet. You can also install just the tools on your home screen.
Saving needs a few MB after you turn it on (large tools add more when used). Login information is never saved, and you can turn it off any time. Tools that need the server, such as the QR maker, web page checker, My IP and secret notes, do not work offline.
