Tools for Protium teams.

Fast, focused utilities that run entirely in your browser — your files never leave your device.

/

Code Genie

Format, validate, minify and compare code. JSON gets a tree view & JSONPath search, a two-pane diff, and HTML/CSS/JS get a live Simulate preview.

Documents & Diagrams

PDF & Image Tools

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

Delimiter Tool

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

Mermaid Studio

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.

Markdown Studio

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

Whiteboard

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

Calculators

Loan Calculators

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

Date & Time Calculators

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

Utilities

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