How do I generate secure Base64 secrets for API keys?

Use our 'Generate Secret' feature to create cryptographically secure random Base64 strings. Choose your desired length (recommended: 32+ characters for API keys, 64+ for encryption keys). Each secret uses crypto.getRandomValues() for true randomness.

Can I encode files to Base64?

Yes! Upload any file up to 5MB and get its Base64 representation. This is perfect for embedding images in CSS/HTML (data URIs), encoding binary data for APIs, or including files in JSON payloads. Large files are processed in chunks for efficiency.

What's URL-safe Base64 encoding?

URL-safe Base64 replaces '+' with '-' and '/' with '_', and removes padding '=' characters. This prevents issues when Base64 data is used in URLs or filenames. Our tool can convert between standard and URL-safe Base64 automatically.

How do I encode text with different character encodings?

Select from UTF-8 (default), UTF-16, ASCII, or Latin-1 encoding options before converting. This is crucial when working with international text or legacy systems. The decoder auto-detects the encoding when possible.
