Frequently Asked Questions
When should I use Base64 encoded images?
Base64 images are perfect for small icons, logos, or when you need to embed images directly in CSS, HTML, or JSON without external file dependencies.
Why does Base64 make files larger?
Base64 encoding represents binary data using text characters, which increases size by about 33%. This trade-off eliminates separate HTTP requests.
What image formats are supported?
All common web image formats are supported: PNG, JPG/JPEG, WebP, GIF, SVG, and more.
Is there a file size limit?
Yes, files are limited to 5MB to ensure good performance. Very large Base64 strings can impact page load times.
