What can this Base64 converter do?

It encodes/decodes Base64 for text, converts files/images to Base64, generates Data URIs, and can decode Base64 back into a downloadable file.

Is there a file size limit?

Yes. The File tab supports up to 10MB per file (the limit is enforced in the browser).

After encoding a file or image, use the Data URI option to copy a string like data: ;base64, .

Paste a Base64 string (optionally with a data: ;base64, prefix), enter a filename, then click Decode to File.

No. All conversions run locally in your browser.
