Base64 Encoder/Decoder
Encode text or files (images, PDFs) to Base64 or decode Base64 to text or files. View, copy, or download results, and keep a history of your operations.
What is Base64?
Base64 is an encoding scheme that converts binary data (text, images, files) into an ASCII string format using 64 printable characters (A-Z, a-z, 0-9, +, /). It’s commonly used in APIs, emails, JWTs, or embedding images in HTML/CSS.
Encoding & Decoding
Encode text or files (e.g., images, PDFs) to Base64 for safe transmission, or decode Base64 back to text or files. For example, Hello, World! encodes to SGVsbG8sIFdvcmxkIQ==.
Base64 encoding uses a 64-character alphabet to represent binary data:
- Alphabet: A-Z, a-z, 0-9, +, /
- Padding: Uses = to pad the output to a multiple of 4 characters
- Use Cases: Embedding images, encoding JWT payloads, or storing files in text formats
Example: SGVsbG8sIFdvcmxkIQ==
- Ensure input for decoding is valid Base64 to avoid errors
- Use UTF-8 encoding for text to prevent corruption
- Check file sizes (max 100MB) to avoid performance issues
- Validate Base64 strings before processing in APIs
- Use Base64 for encoding, not encryption—encrypt sensitive data first

Get geeky with it — Base64 is your data playground!
Is Base64 encoding secure?
Nope, it's just encoding, not encryption. Encrypt sensitive data first!
What file types can I encode?
Images, PDFs, or any file up to 100MB — but previews work best for images.
Are my inputs saved?
Only in your browser's local storage — nothing goes to a server.
Can I decode any Base64 string?
Yep, as long as it's valid (A-Z, a-z, 0-9, +, /, =). Invalid strings will error.
Is it free to use?
100% free, no sign-ups, no ads. Just encode or decode away!
Alright, whether you're prepping data for APIs, embedding images, or just nerding out with Base64, the Encoder/Decoder is your trusty tool. Paste text, upload files, or decode strings, and get results fast with previews and downloads. Share your Base64 adventures with your dev crew and keep the data flowing!
