FAQ
Is the restored file identical to the original?
Yes. Base64 encoding and decoding is a lossless conversion. If the correct Base64 string is provided, the restored file will be 100% identical to the original.
How do I specify the file name?
After decoding, you can enter your desired file name and extension. Make sure to specify the correct extension (.png, .pdf, etc.) so the file opens properly.
