About Image to Base64 Converter

Convert images to Base64 encoded strings for embedding in HTML, CSS, or JSON.

Frequently Asked Questions

What is Base64 image encoding?
Base64 image encoding converts binary image data into an ASCII text string. This allows you to embed images directly in HTML, CSS, or JSON without needing a separate image file, which can reduce HTTP requests and simplify deployment.
Which image formats are supported?
This tool supports all common image formats including PNG, JPEG, GIF, SVG, WebP, and ICO. Simply drag and drop or browse to select any image file from your device.
When should I use Base64 encoded images?
Base64 encoding is ideal for small images like icons, logos, and thumbnails where reducing HTTP requests matters. For larger images, serving them as separate files is usually more efficient since Base64 increases the data size by approximately 33%.
Is my data safe?
Yes! All processing happens entirely in your browser. Your images are never uploaded to any server. No data is collected, stored, or transmitted.
Why is the Base64 output larger than the original file?
Base64 encoding represents binary data using 64 ASCII characters, which increases the size by roughly 33%. A 100KB image becomes about 133KB in Base64. This is a normal trade-off for the convenience of inline embedding.
