Base64 Encoder / Decoder
Why Use Base64?
Base64 encoding isn't for encryption, but Tooly finds it useful for:
- Data Transmission: Safely send binary data (like images or files) over mediums that only reliably support text (like JSON or XML).
- Embedding Data: Embed small binary data directly into URLs (Data URIs), HTML, or CSS without needing separate files.
- Obfuscation (Basic): Makes text non-human-readable at a glance, though easily reversible.
- Compatibility: Ensures data remains intact when passing through systems that might misinterpret certain characters.
Tooly handles the conversion reliably, supporting UTF-8 characters and URL-safe variants!
What is Base64 Encoding?
Base64 is a group of binary-to-text encoding schemes that represent binary data in an ASCII string format by translating it into a radix-64 representation.
It uses a set of 64 characters (A-Z, a-z, 0-9, +, /) to encode any sequence of bytes. Padding with `=` characters might be added at the end to ensure the output length is a multiple of 4.
The "URL and Filename Safe" variant replaces `+` with `-` and `/` with `_` to avoid conflicts in URLs and filenames, and often omits the padding.
How to Use Tooly's Base64 Tool
Enter Input
Paste the text you want to encode OR the Base64 string you want to decode into the input area.
Choose Action
Click "Encode to Base64" to convert plain text to Base64.
Or Decode
Click "Decode from Base64" to convert a Base64 string back to plain text.
URL Safe Option (Optional)
Check the "URL & Filename Safe" box *before* encoding if you need the output to be safe for URLs or filenames.
