Tools for Protium teams.

Combine, compress, split and convert PDFs; crop, resize, convert and shrink images — all on your machine.

Turn a column or list into a delimited, quoted list — dedupe, sort, wrap and more.

Convert CSV to JSON and back with a proper parser, or paste CSV into a clean, dedupe-able table — all in your browser.

Build diagrams as code — flowcharts, sequence, ER, class, state, gantt and more. Live preview with pan & zoom, open .mmd/.md files, export SVG / PNG / PDF.

Write Markdown, see it beautifully rendered, and copy it as rich text into Teams, Confluence or Outlook — or export HTML/PDF.

A free-form infinite canvas — sketch boxes, arrows and notes, then export to PNG/SVG. Autosaved on your device; nothing is uploaded.

EMI (home / personal / car), loan eligibility, flat ↔ reducing rate, simple & compound interest, and amount-in-words.

Epoch/Unix converter, world clock, age, date difference, add/subtract, time duration and time zones.

Plan and read experiments: required sample size, statistical significance, confidence intervals, and a safe way to peek early.

Pixel-perfect inspection — color picker, zoom and HEX/RGB/HSL.

Base64 / URL / Hex encode & decode, MD5 & SHA hashes, and a JWT decoder that reads claims and expiry — all on your device.

Change case, clean & trim, sort and dedupe lines, find & replace (regex), and count words, lines and characters.

Generate single or bulk universally-unique identifiers.

Create secure, unpredictable passwords instantly.

A full-screen white / black / colour screen — clean your monitor, hunt dead & stuck pixels, use it as a lightbox, or run colour, gradient and checkerboard test patterns.
