Base64 Converter details

Encode and decode Base64 strings with UTF-8 support for developer payloads. Base64 Converter is now a native Toolars workspace for local UTF-8 encoding, decoding, and URL-safe payload cleanup.

Overview

Base64 Converter encodes UTF-8 text into standard or URL-safe Base64 and decodes pasted Base64 back into readable text. The workspace migrates the Aixtral source behavior into Toolars-native controls, adds normalization for common copy-paste issues such as missing padding, URL-safe alphabets, whitespace, and data URL prefixes, and keeps payloads local for API debugging, tokens, and configuration review.

How it works

1Paste payload textAdd plain UTF-8 text, a standard Base64 string, a URL-safe token, or a copied data URL directly in the local workspace.Input

2Choose conversion modeSwitch between encode and decode, then pick standard Base64 or URL-safe output for API, JWT, and query-string payloads.Mode

3Normalize safelyDecode flow strips whitespace, converts URL-safe characters, restores missing padding, and reports each cleanup step.Review

4Copy reviewed outputReview byte counts, output length, warnings, and normalized input before copying the converted payload.Output

Local Base64 conversion model

LocalText and Base64 payloads are converted in the browser and are not uploaded for processing.

ValidationMalformed Base64 and invalid UTF-8 are surfaced as explicit errors before the output can be reused.

PublicThis tool has a dedicated Toolars workspace, source-backed library implementation, and focused tests.
