Frequently Asked Questions

What image formats are supported?
The tool supports JPEG, PNG, GIF, WebP, SVG, BMP, ICO, and TIFF formats. Each format has different size limits and compression options available.
How much does Base64 encoding increase file size?
Base64 encoding increases file size by approximately 33%. This is due to the encoding method that uses 4 characters to represent every 3 bytes of binary data.
When should I use Base64 images?
Use Base64 for small images (< 10KB), icons, or when you need self-contained HTML/CSS. For larger images, regular file serving is usually better for performance.
Can I compress images during conversion?
Yes, the tool can apply JPEG compression and resize images to reduce the final base64 size. This is especially useful for optimizing larger images.
Are there any limitations or browser support issues?
Base64 data URLs are well-supported in modern browsers. However, very large images may cause memory issues, and some older email clients have size limits.
