Frequently Asked Questions
Are my files uploaded to a server?
No! All file conversions happen directly in your browser. Your files never leave your device, ensuring complete privacy and security. This also means conversions work offline once the page is loaded.
Is there a file size limit?
Since processing happens in your browser, the limit depends on your device's memory. Most modern devices can handle files up to 50-100MB without issues. For very large files, processing may take longer.
What file formats are supported?
We support popular data formats like JSON, CSV, YAML, and XML, as well as modern image formats like HEIC, WebP, AVIF, and SVG. We're constantly adding new format converters based on user demand.
Do I need to create an account?
No account or signup is required. All tools are completely free to use with no limits on the number of conversions. Just open the tool and start converting.
Will the conversion add watermarks to my files?
Never. All conversions are clean with no watermarks, branding, or modifications beyond the format conversion itself. You get exactly what you expect.
