Convert text to Base64 and back, including full Unicode (emoji, non-Latin scripts). Drop a file to get its Base64 representation, or paste a Base64 data URI to preview it. Useful for data URIs, JWT inspection, API debugging, and embedding small assets in code.
Result appears here…This tool runs 100% in your browser. Nothing you paste, drop, or generate ever leaves your device - no analytics on your input, no uploads, no logs.
Base64 encodes binary data as ASCII text - useful for embedding images in HTML/CSS (data URIs), transferring binary in JSON, JWT payloads, and email attachments.
Standard Base64 uses '+' and '/' which conflict with URL syntax. URL-safe Base64 replaces them with '-' and '_' so the string can be passed in a URL or filename.
No. Base64 is encoding, not encryption - anyone can decode it. Don't use Base64 to protect secrets.
