Frequently Asked Questions
Is Base64 an encryption method?
No, Base64 is only an encoding — anyone can reverse it without a password. Real encryption is needed for confidentiality.
Which file types can I upload?
Any file — images, PDFs, documents or any binary file.
Is my file uploaded anywhere?
No, the encoding happens entirely locally in your browser.
