📋

Copy or Download

One click to copy the output, download as .txt, or generate a data URI for embedding.

◻ Applications

Who Uses It

Used by developers, designers, and security engineers daily.

Frontend

Inline Assets

Convert images to Base64 data URIs to embed directly in HTML/CSS without separate HTTP requests.

Backend

API Payloads

Encode binary data for safe transmission in JSON, XML, or any text-based protocol.

Security

Token Inspection

Decode JWT tokens, OAuth credentials, and auth headers to inspect their payload instantly.

DevOps

Config & Secrets

Encode/decode secrets stored in environment variables, Kubernetes secrets, or .env files.

QA

Hash Verification

Generate SHA-256 checksums to verify file integrity or compare content without running code locally.

Email

MIME Encoding

❓ Questions

Frequently Asked

Everything about Base64 Encoder & Dev Tools.

What is Base64 encoding?⌄
Base64 is an encoding scheme that converts binary data into ASCII text using 64 printable characters. It's commonly used to embed binary data (images, files) inside text formats like HTML, CSS, JSON, and email.
Does this tool send my data anywhere?⌄
Never. All encoding, decoding, and hashing happens entirely in your browser using native JavaScript APIs (btoa, atob, TextEncoder, SubtleCrypto). Nothing is sent to any server.
What's the difference between URL-safe and standard Base64?⌄
Standard Base64 uses + and / which are special characters in URLs. URL-safe Base64 replaces + with - and / with _ so the output can be used in URLs, query strings, and filenames without percent-encoding.
What hash algorithms are supported?⌄
MD5 (pure JavaScript), SHA-1, SHA-256, SHA-384, and SHA-512 (all via the browser's built-in SubtleCrypto API). SHA-256 is recommended for most use cases.
Can I encode images and files?⌄
Yes. The Image and File tabs let you drag-and-drop or select any file up to 10MB. You get the raw Base64 output or a complete data URI that can be embedded directly in HTML or CSS.
What are the extra encoding tools?⌄
Beyond Base64, you can URL-encode/decode, HTML-entity encode/decode, convert text to hexadecimal, convert text to binary, and generate cryptographic hashes — all zero-API, browser-native.
