About Image to Base64
Frequently Asked Questions
What is Base64 encoding?
Base64 is a way to represent binary data (like images) as text characters. It uses 64 safe ASCII characters to encode any type of data.
Why convert images to Base64?
To embed images directly in HTML/CSS/JS files, eliminate HTTP requests, create self-contained documents, or store images in text-based formats like JSON.
When should I use data URI prefix?
Include it when embedding in HTML/CSS (e.g., background-image, img src). Exclude it when storing pure Base64 or transmitting via certain APIs.
Are Base64 images larger than originals?
Yes, about 33% larger. Base64 trades file size for convenience. Best for small images where the extra size is offset by reducing HTTP requests.
What image formats are supported?
All common formats: PNG, JPG/JPEG, GIF, WebP, SVG, ICO, and BMP. The tool detects the format automatically from the file.
Can I convert animated GIFs?
Yes! The entire animated GIF including all frames is encoded. When decoded, the animation plays normally.
Is there a file size limit?
Browser memory is the only limit. However, Base64 is best for small images. Large files (over 100KB) may cause performance issues when embedded.
How do I use the result in CSS?
Use background-image: url('data:image/png;base64,YOUR_STRING_HERE'); – make sure to include the data URI prefix.
How do I use it in HTML?
Use <img src='data:image/png;base64,YOUR_STRING_HERE'> – again, include the data URI prefix for this to work.
Is my image data secure?
Completely. Everything processes locally in your browser. Images are never sent to any server, so your data stays private.
