▶ About This Tool
YouTube to MP4 lets you save any YouTube video as a standard MP4 file on your device — to watch offline, share, archive, or use in a project. FormatSwitch uses yt-dlp, the most actively maintained YouTube downloader, to fetch the video stream and remux it to MP4.
Quality options range from 144p up to 4K (2160p) where available. The "Best available" option automatically selects the highest quality the video offers.
Common Use Cases
- 📴 Save videos to watch offline without an internet connection
- ✈️ Download travel guides, tutorials, or lectures before a flight
- 🎬 Archive a video you created or that you have permission to save
- 🎓 Download educational content for offline study sessions
Tips & Notes
- → Not all YouTube videos are available at every quality level — if 4K is selected but not available, yt-dlp falls back to the next best quality automatically.
- → Shorts and regular videos both work. Live streams and private/members-only videos cannot be downloaded.
- → If you only need audio, use YouTube to MP3 instead — it is faster as no video track needs to be processed.
- → Very long videos (2+ hours) take longer to process. The download link remains valid for 10 minutes after conversion.
- → MP4 is the most universally compatible video format — it plays on every phone, tablet, TV, and computer without additional codecs.

Format-Specific Tips
JSON → YAML
Great for Kubernetes configs and Docker Compose. FormatSwitch preserves array ordering and nested objects. Multi-line strings are automatically represented with YAML block scalars.
YAML → JSON
Useful when feeding config data into APIs or Node.js scripts. All YAML anchors and aliases are resolved before output.
CSV → JSON
The first row is treated as the header. Each subsequent row becomes a JSON object. Works with comma or semicolon delimiters.
JSON → XML
Array elements are wrapped in <item> tags. JSON keys become XML element names. Best for SOAP or legacy enterprise integrations.
Base64 Encode / Decode
Paste raw text or a data URI and toggle encode/decode. Useful for JWT payloads, email MIME parts, and CSS background images.
Markdown → HTML
Full CommonMark support: headings, bold, italic, links, images, code blocks, and tables. Output is clean, unstyled HTML ready to embed.
URL Encode / Decode
Encodes all reserved characters per RFC 3986. Useful for query strings, OAuth parameters, and debugging percent-encoded URLs.
Text ↔ HEX
Converts each character to its hexadecimal byte representation. Handy for inspecting binary protocols or generating CSS color values.
Case Conversion
Converts identifiers between camelCase, snake_case, PascalCase, kebab-case, UPPER_SNAKE, and lowercase. Handles multi-word phrases intelligently.
