Frequently Asked Questions

What is Base64?

Base64 is a method that turns an image (a binary file) into text made only of letters and numbers. That text can then be placed directly inside HTML, CSS or an email, without a separate image file.

Is my photo uploaded anywhere?

No. The conversion happens inside your browser — no server, no upload. Your photo never leaves your device.

Why is the Base64 code bigger than the original?

In Base64 encoding, every 3 bytes become 4 characters, so the code is about 33% bigger than the file. For large photos, reduce the size first with the Image Compressor.
