Frequently Asked Questions
Is Base64 encryption?
No. Base64 is an encoding scheme, not encryption. It can be easily reversed by anyone and provides no security or privacy for your data. Do not use it for sensitive information like passwords.
Why use Base64 for images?
Encoding small images as Base64 allows you to include them directly in your HTML or CSS, reducing the number of HTTP requests a browser needs to make to load your page.
Are there size limits?
Base64 encoding increases the file size by about 33%. For very large files, this can lead to performance issues. We recommend using it for small icons, snippets, or temporary data transfers.
