What is Base64 Image Encoding?
Base64 is a binary-to-text encoding scheme that translates raw image bytes into a sequence of 64 ASCII characters. By converting an image to Base64, you can embed icons, logos, and graphics directly into HTML files, CSS stylesheets, or JSON API payloads without triggering extra HTTP network requests.
When should you use Base64?
- Small UI Icons & Badges: Eliminates network latency for critical above-the-fold icons.
- Email Templates: Embed small logos directly into HTML newsletters to ensure they load offline.
- Single-File Webpages: Create completely self-contained HTML documents that require no external image hosting.
Frequently asked questions
Does Base64 increase file size?
Yes. Base64 strings are approximately 33% larger than raw binary images due to 6-bit to 8-bit ASCII representation. For large photos, normal JPG/PNG files are recommended.
Is it safe to paste private images?
Yes. The encoding and decoding run 100% in your local browser sandbox.
