Frequently Asked Questions
Can this tool decode any file type?
Yes, Base64 is a generic binary-to-text encoding. As long as you provide valid Base64 data representing a file, this tool can decode it back to the original binary file.
Is there a size limit?
Since the processing runs in your browser, the limit depends on your device's memory and browser capabilities. Very large strings (hundreds of MBs) might cause the browser to slow down.
Is it secure?
Yes, completely secure. The decoding logic runs client-side in your browser, so your private data never leaves your computer.
