Drop any image (JPG, PNG, WebP, SVG, GIF, AVIF) and get a Base64 data URI ready to paste into CSS, HTML, JSON, or anywhere you need to embed image data inline. Includes the proper MIME type prefix (data:image/jpeg;base64,...) so the output is directly usable.
When to use this
Use when: embedding small images in CSS to avoid a network request, including images in HTML email bodies, inlining logos in CSP-strict environments, generating self-contained HTML reports with images, embedding tiny icons in JSON payloads.
Frequently Asked Questions
Should I always use Base64 for images?
No - Base64-encoded images are ~33% larger than the original binary. Use it for small images (icons, logos under 5 KB) where the network-request saving outweighs the size bloat. For large images (photos, hero images), a normal <img> with HTTP caching is much better.
Can I decode this back to an image?
Yes - any Base64 data URI can be decoded back to the original image. Use our Base64 Decoder, or just paste the data URI into any browser's address bar - it'll render the image directly. The decoded bytes are byte-identical to the original file.
