FAQ
Base64 Encoder FAQ
Common questions answered about this free tool.
What is Base64 used for?
Encoding binary data for email attachments (MIME), embedding images in HTML/CSS as data URIs, storing binary data in JSON, and transmitting data in APIs.
Does Base64 increase file size?
Yes. Base64 encoding increases data size by approximately 33%. Use it for small data or when necessary for transmission.
Are these developer tools free?
Yes, all our developer tools are completely free with no usage limits. Use them as much as you need for your development work.
Do you store my code or data?
No. All processing happens client-side in your browser. Your code and data never leave your device.
What is the maximum input size?
Most tools handle inputs up to several megabytes. For JSON formatter and validators, very large files (over 10MB) may cause slower performance.
Can I use these tools in my CI/CD pipeline?
These tools are designed for browser use. For programmatic access, we recommend using dedicated CLI tools or libraries.
Are the formatters configurable?
Yes, formatters typically include indentation settings (spaces vs tabs). JSON formatter supports different indentation levels.
What encoding standards are supported?
Base64 encoder/decoder supports standard Base64 with padding. URL encoder follows RFC 3986 encoding standards.
Can I validate JSON against a schema?
The JSON Validator checks syntax validity and structure. For JSON Schema validation, you would need specialized tools.
Are the CSS generators production-ready?
Yes, all generated CSS follows W3C standards and works in all modern browsers. Browser prefixes are included where needed.
