Frequently Asked Questions
Is encoding free?
Yes. No limits, accounts, or uploads — FileReader runs entirely in your browser.
Clipboard blocked?
Some browsers require a secure context (HTTPS) for navigator.clipboard. You can still select the text manually.
When use a Data URL?
Great for small inline images in HTML/CSS or quick prototypes. Large files bloat markup.
Why raw Base64?
APIs and JSON payloads often want only the encoded payload without the data: prefix.
Can I re-encode after changing format?
Change the radio option and add files again, or clear and re-drop to apply the new mode to a batch.
