About FormatSwitch — Free File & Format Converter
FormatSwitch is a free, browser-based conversion tool that supports over a dozen popular file and data formats. No account needed, no file size limits for text formats, and no data is retained after conversion.
📄 PDF to Word (DOC / DOCX)
Convert PDF files into fully editable Word documents online — no software needed. Preserves headings, paragraphs, and tables. Ideal for contracts, reports, and scanned text. Upload your PDF and download an editable DOCX in seconds.
📝 Word (DOCX) to PDF
Turn Word documents into polished, share-ready PDFs instantly. Perfect for protecting formatting across devices when printing or sending to clients. Works entirely in your browser with fast, server-side processing.
🔄 JSON ↔ YAML
Instantly switch between JSON and YAML — the two most popular data serialization formats used by developers. Perfect for Kubernetes manifests, Docker Compose files, CI/CD pipelines, and REST API development.
🔁 JSON ↔ XML
Convert JSON objects to valid, well-formed XML markup and back again. Useful for integrating with SOAP APIs, legacy enterprise systems, and transforming config files across formats.
📊 CSV ↔ JSON
Transform Excel exports and database CSV dumps into clean JSON arrays — or reverse the process. Great for ETL pipelines, front-end data tables, and feeding structured data into APIs.
🔐 Base64 Encoder / Decoder
Encode text, binary data, or images to Base64 and decode back to plaintext. Commonly used in JWT tokens, email MIME attachments, Data URIs, and embedding images directly into HTML or CSS.
🔗 URL Encoder / Decoder
Percent-encode special characters for safe use in URLs, query strings, and API parameters. Also decodes URL-encoded strings back to human-readable text — handy for debugging web requests.
🔒 Private & Secure
Text conversions are processed instantly without storing your data. File conversions (PDF/DOCX) are handled server-side over HTTPS and are never logged or shared. Your data stays yours.
Frequently Asked Questions
Is FormatSwitch completely free?
Yes — 100% free with no account, no subscription, and no hidden limits. The tool is supported by non-intrusive display advertising only.
Is my data safe and private?
Text conversions happen in PHP and are returned over HTTPS — nothing is written to a database or log. File uploads (PDF/DOCX) are processed ephemerally and deleted after delivery.
Which formats are supported?
JSON, YAML, XML, CSV, Excel CSV, TOML, Base64, URL encoding, Markdown → HTML, Text ↔ HEX, Case Conversion (camelCase, snake_case, PascalCase, kebab-case), and PDF ↔ DOCX.
Can I convert large files?
Text conversions handle large payloads efficiently. For files over 5 MB, a local CLI tool like jq, yq, or pandoc may perform better. PDF/DOCX conversions are limited to reasonable sizes.
Do I need to install anything?
No. FormatSwitch runs entirely in your browser (for text) and server-side (for files). There is nothing to install, configure, or sign up for.
Can I convert PDF to Word without losing formatting?
Our PDF to DOCX converter uses pdfplumber and python-docx to preserve paragraphs, headings, and tables as accurately as possible — no LibreOffice required.
