Base64 Encoding utility

Last updated: 7/25/2025

This online utility converts various file types into Base64 encoded strings right in the browser. This allows you to embed various types of files directly into your HTML document using Base64 encoding and the data URI scheme. This means the browser doesn't have to make separate HTTP requests to fetch these resources, potentially improving page load times for smaller files, and the HTML file can be self-contained.

This utility creates fully functional HTML snippets which can be inserted into your HTML document.

Supported file types include:

• PNG, JPG, JPEG, GIF, SVG, WEBP, APNG image files
• MP3, OGG, WAV audio files
• MP4, OGV, WEBM video files
