Frequently Asked Questions
What is Base64 encoding?
Base64 is a method of encoding binary data (like images) into ASCII text characters. This allows you to embed images directly in HTML, CSS, or JSON without needing a separate image file.
Does Base64 increase the file size?
Yes, Base64 encoding increases the data size by approximately 33%. A 100KB image will produce a Base64 string of about 133KB. It is best used for small images, icons, and thumbnails.
When should I use Base64 images?
Base64 is ideal for small images (under 10KB), email templates where external images may be blocked, single-page apps where you want to reduce HTTP requests, or CSS sprites and icons.
Is my image uploaded to a server?
No. The entire encoding process runs locally in your web browser. Your image file is read by the browser's FileReader API and never sent to any server.
