Frequently Asked Questions

Is Base64 encoding suitable for large images?

Base64 encoding increases file size by roughly 33% and is generally best suited for small images like icons rather than large photos.

Can I use the generated Base64 string directly in an tag?

Yes, you can use it in the format data:image/png;base64,... as the src attribute value in an HTML image tag.

Does converting to Base64 upload my image anywhere?

No, encoding happens locally in your browser using JavaScript, so your original image file isn't uploaded to any server.
