Should I minify JSON before base64 encode json string for api?

Minified JSON is smaller; pretty JSON with spaces also encodes correctly but yields a longer Base64 string.

Does encoding change JSON semantics?

No. Decoding the Base64 output returns the exact UTF-8 bytes of your JSON text.

Use the JSON formatter pages to confirm syntax before copying into this encoder.

Some REST and gRPC gateways require JSON configuration or event bodies transported as a single Base64 field.

Paste minified or formatted JSON in encode mode to produce the Base64 representation your schema expects.

Integration developers align with webhook docs that describe base64-encoded JSON blobs without writing throwaway scripts.
