The Problem

Online Base64 tools are ad-infested and have file size limits. No tool handles bulk encoding/decoding. Developers need API access for automation. Image-to-Base64 conversion requires separate tools. CLI tools lack visual feedback for debugging encoded data.

The Solution

Clean, fast Base64 encoder/decoder for text, files, and images — with batch processing, multiple encoding variants (URL-safe, MIME), and a developer API.

Target Audience

Developers encoding data for APIs and email, DevOps engineers working with certificates and configs, and QA engineers decoding Base64 payloads for testing
