Frequently Asked Questions
Do I need to upload my file to use these converters?
No. All conversions run in your browser using JavaScript. Your files and text never leave your device.
Can I convert large files?
Browser-based tools work well for most use cases. Very large files (over a few MB) may be slower depending on your device, but there is no hard size limit imposed by the server.
Which Base64 variant do the tools use?
Standard RFC 4648 Base64 with the = padding character. The URL-safe variant (using - and _ instead of + and /) can be toggled in the Base64 Converter tool.
