Date & Time Studio — Unix Timestamp & Time Zone Converter
Paste a Unix timestamp or almost any date string — the unit and format are detected automatically and shown in 15 formats and multiple time zones. DST gaps, month ends and Japanese era boundaries are handled precisely.
Encode / Decode Studio — Base64, URL, JWT & more
Paste %E3%81%82, an eyJ… token or any encoded string — the format is detected and decoded instantly. Errors say exactly which character is wrong and why, and nothing leaves your browser.
Markdown Studio — Live Editor & Preview
A split-view Markdown editor with instant GFM preview, a table formatter that aligns pipes, an automatic table of contents and HTML export. Output is always sanitized and external images load only when you allow them.
Text Studio — Character Counter & Text Cleaner
Paste text to see characters, words, lines and bytes instantly, then clean it up in one click — change case, remove duplicate or blank lines, sort naturally, convert line breaks. Every action reports what changed and can be undone.
Unicode Inspector — Character & Invisible Text Analyzer
Paste text to break it into characters with U+ codes, byte sequences and categories. Hidden zero-width spaces, BOMs, bidi controls and look-alike letters are detected and can be removed in one click.
IT Calculator (Storage, Transfer, Uptime, RAID)
Convert storage units (SI GB vs IEC GiB), estimate transfer time from file size and line speed, turn an uptime percentage into allowed downtime, and size RAID arrays, all with the formula shown. Type values with units, like “1.5GB” or “100Mbps”.
MIME & Content-Type Studio
Search extensions and MIME types both ways, get problems in a Content-Type header pointed out, and compare a dropped file’s extension, browser file.type and real content. Server config drafts are generated too.
QR Code & Barcode Reader
Drop an image or point your camera to read QR codes and barcodes. URLs are never opened automatically — you see the real destination domain and phishing warnings first. Everything runs on your device.
QR & Barcode Studio
Build QR codes from templates for Wi-Fi, contacts, events and more, and barcodes such as EAN or Code 128 with automatic check digits. Export PNG or SVG, or batch-create one code per line.
