Is image to Base64 conversion private?

Encoding runs in your browser after you upload. HEIC files are decoded on the server first because browsers cannot read HEIC natively, then encoding continues locally.

Should I use a data URL or raw Base64?

APIs and HTML img src attributes often want a full data:image/…;base64,… URL. Raw Base64 is for JSON payloads that expect only the encoded string.

Can I decode Base64 here too?

Yes. Use the Base64 to Image tool on /base64-to-image to paste a string and download the decoded file.
