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
About Base64 Encoder/Decoder
Hey devs! Welcome to the Base64 Encoder/Decoder on Random Fun Generator—your one-stop shop for encoding text or files (like images and PDFs) to Base64 or decoding them back. Whether you’re prepping data for APIs, embedding images in CSS, debugging JWTs, or just geeking out, this tool’s got you covered.
Base64 is like a universal translator for data—it takes text, images, or any binary file and turns it into a string of 64 safe ASCII characters (A-Z, a-z, 0-9, +, /). It’s not encryption, just a way to make data text-friendly for JSON, APIs, or email attachments. This tool lets you encode text or files up to 100MB and decode Base64 back to text or downloadable files.
Try it out: paste text like Hello, World! to get SGVsbG8sIFdvcmxkIQ==, or upload an image to encode it to Base64. Decoding works the same—paste a Base64 string, and get text or a file with a preview for images. You can copy results with one click, download decoded files, and check your history, all stored in your browser.
The UI’s slick with purple-indigo vibes, smooth animations, and tabs for encoding/decoding, built to run fast on Cloudflare Pages. It’s perfect for developers testing API payloads, embedding images in HTML, or learning Base64. For images, you’ll see a preview, and for files like PDFs, you can download the decoded result.
Security heads-up: Base64 isn’t encryption, so don’t encode sensitive data without encrypting it first. Check that your Base64 strings are valid (A-Z, a-z, 0-9, +, /, =) to avoid errors, and keep file sizes under 100MB. The tool validates inputs and shows clear error messages if something’s wrong.
Whether you’re a backend ninja, frontend wizard, or just curious, this tool’s your go-to for Base64 tasks. No logins, no server calls—just paste or upload, encode or decode, and copy or download. Share your results with the dev squad using the share button, and keep the web fun and functional!
