Base64 Encoder / Decoder
Convert ordinary UTF-8 text to Base64, decode Base64 snippets, and copy the result without uploading raw payloads or storing them in custom analytics.
Encode quick text snippets for tests and decode Base64 samples while keeping the conversion inside the browser tool flow.
Result
How it works
Choose encode or decode intentionally
Use Encode for plain UTF-8 text and Decode only when you expect a Base64 value. Base64 is an encoding format, not encryption or access control.
Use harmless payloads
Work with sample text, fixtures, and documentation examples. Do not paste real passwords, bearer tokens, private keys, credentials, or regulated data.
Inspect decoded text before reuse
Read the decoded output before copying it into code, docs, tickets, or another tool because decoded text can reveal hidden identifiers or private values.
Examples
Encode a word
Input: hello -> Encode
Output: aGVsbG8=
Decode a word
Input: aGVsbG8= -> Decode
Output: hello
Unicode text
Input: 안녕 SOLVEOZA -> Encode
Output: 7JWI64WVIFNPTFZFT1pB
URL-safe input
Input: SGVsbG8td29ybGQ -> Decode
Output: Hello-world
Config sample
Input: api:test -> Encode
Output: YXBpOnRlc3Q=
HTTP Basic test value
Input: demo:password -> Encode
Output: A sample authorization value to inspect, not a production secret
Whitespace cleanup
Input: YQ== with spaces -> Decode
Output: a
Invalid Base64
Input: not valid *** -> Decode
Output: Safe validation message
FAQ
Does SOLVEOZA upload my Base64 text?
No. This Base64 tool runs in the browser tool flow and does not send raw payloads to a SOLVEOZA conversion server.
Does SOLVEOZA store decoded text or encoded output?
No. Custom analytics may record coarse tool events only, not raw payloads, decoded text, encoded output, filenames, keys, or values.
Can this decode URL-safe Base64?
Yes. Decode mode accepts standard Base64 and common URL-safe Base64 characters, then normalizes padding before decoding.
Can this encode Unicode text?
Yes. Encode mode converts UTF-8 text to Base64, so non-ASCII text can be encoded for quick development checks.
Should I paste secrets or tokens?
Avoid pasting API keys, access tokens, passwords, credentials, private URLs, regulated data, or confidential production values into any web tool unless your policy allows it.
Is Base64 encryption?
No. Base64 is encoding, not encryption. Anyone can decode it, so do not use Base64 alone to protect sensitive data.
Why does decoding fail?
The input may contain unsupported characters, broken padding, or bytes that are not valid UTF-8 text. The tool returns a generic error without echoing the private input.
Can I convert very large payloads?
Not in this first browser-safe slice. Input is capped at 512 KiB and converted output is capped at 2 MiB.
