Frequently Asked Questions

Everything you need to know about using JSON to YAML.

Is it safe to use JSON to YAML with confidential files?
Yes, absolutely. JSON to YAML processes everything locally inside your web browser. Your files are never uploaded to any external server. This client-side architecture ensures complete data privacy and makes the tool safe for handling sensitive, confidential, or proprietary content.
Does converting with JSON to YAML reduce quality?
The conversion process is designed to preserve maximum quality. For lossless formats like PNG, quality is identical to the original. For compressed formats like JPG, the tool uses optimized encoding to maintain visual fidelity while achieving efficient file sizes.
Is there a file size limit for JSON to YAML?
Since all processing happens in your browser, there are no server-imposed file size limits. The practical limit depends on your device's available memory (RAM). Most modern devices can handle files up to 100MB comfortably. For very large files, ensure you have sufficient free memory.
Can I convert multiple JSON files at once?
The tool supports batch processing for premium users. Free users can process files one at a time. Each file is converted independently, ensuring consistent quality across all your conversions. Simply upload additional files after each conversion completes.
Can I use JSON to YAML on my phone or tablet?
Yes, the tool is fully responsive and works on mobile browsers including Chrome, Safari, and Firefox on both Android and iOS devices. The interface adapts to your screen size for a comfortable experience. However, very large files may process more slowly on mobile devices compared to desktop computers.
How fast does JSON to YAML process files?
Processing speed depends on your file size and device capabilities. Small files typically complete in under 2 seconds. Larger files may take 5-15 seconds. Since everything runs locally, processing speed is not affected by your internet connection — it depends entirely on your device's processing power.
