Converters tools
Instant unit and format converters — length, weight, temperature, colors, and more. Fast, accurate, and private, with most running right in your browser.
- Color Converter (HEX, RGB, HSL)
A color converter that reads hex, CSS names, rgb(), hsl() and oklch(), and writes each one back with CMYK and the nearest named color.
- CSV to XLSX Converter (and back)
CSV to XLSX or an Excel sheet back out as CSV, with the separator read from the data and a wrong split refused before it reaches a workbook. Every cell stays text.
- Currency Converter (ECB rates)
A currency converter built on the European Central Bank's daily reference rates: 30 currencies, cross-rated through the euro, with the publication date printed under every result.
- DOCX to HTML
DOCX to HTML with semantic tags and none of Word's span soup. Preview it, copy the markup, or save a styled standalone page.
- DOCX to Markdown
Convert DOCX to Markdown with ATX headings, hyphen bullets, working links and GFM pipe tables. Copy the output or save it as a .md file under the original name.
- DOCX to Text
Convert a .docx to text and keep only the words, with Word's fonts and spacing left behind. Copy the result or save a .txt that keeps the document's name.
- Excel to PDF
Excel to PDF for a workbook someone only needs to read: tick the sheets worth sending, choose A4 or US Letter, portrait or landscape, and each sheet lands as its own page of selectable text.
- Markdown to PDF
Markdown to PDF that keeps the text selectable and searchable. A4 pages, an 11pt body, code on a light grey panel, links still clickable.
- Markdown to Word (DOCX)
Markdown to Word, done properly: paste your notes and download a real .docx that Word, Google Docs or Pages will edit. Headings map onto Word's own Heading 1 to 6, code lands in Courier New.
- Morse Code Translator
Morse code translator that runs both ways, on 54 characters of the international table, with a Play button that beeps the result at 15 words per minute.
- Number Base Converter
Number base converter for binary, octal, decimal and hex, reading input written in any base from 2 to 36. BigInt math, so a 128-bit value converts exactly.
- PDF to Word
Convert a PDF to an editable Word .docx that keeps its columns, ruled tables, headings and pictures, or switch to Exact layout and pin every line to the coordinates the page gave it.
- Smart JSON to CSV Converter (and back)
JSON to CSV with the header row built from your keys, or CSV back to JSON with numbers, booleans and nested objects restored.
- Subtitle Converter & Sync Fixer
Convert SRT to VTT and back, retime cues that drift out of sync, and fix the wording in an editable table of every line.
- Unit Converter
A unit converter with 19 categories, from cm to inches and kg to lbs through pressure, torque and data rate. Pick two units and read the answer as you type.
- Word to PDF
Word to PDF without opening Office. Give it a .docx and you get back an A4 document with selectable text and links that still click.
- YAML to JSON Converter (and back)
Convert YAML to JSON, or JSON back to YAML. Output comes back pretty-printed at two-space indent, and a manifest that won't parse gets an error naming the line.
- Zip & Unzip Files
Zip files and folders into one archive with the subfolder paths kept, put an AES-256 password on it if it needs one, or open a .zip and pull out the entry you wanted.
These converters turn one unit or format into another instantly — length, weight, temperature, volume, area, speed, digital storage, and time units; colors between HEX, RGB, and HSL; numbers between binary, octal, decimal, and hexadecimal; and structured data between JSON, CSV, and YAML. Type a value and the result updates as you go.
Each runs entirely in your browser, so the data you paste — a config file, a spreadsheet column, a color value — stays on your device. Where it helps, conversions are shareable: the unit converter deep-links every pair, so the one you use often is a saved link away.
