(FAQ)
How to decode Base64 encoding?
To decode Base64 encoding, paste the encoded text into the Base64 Encoder Decoder tool and click the Decode button. The tool instantly converts the Base64 string back into readable text or data.
How to identify Base64 encoding?
Base64 encoded strings usually contain characters like:
A–Z, a–z, 0–9, +, /, and may end with = padding characters.
These patterns help identify base64 code in logs or data streams.
How to decode Base64 to image?
To base64 decode image, paste the encoded image string into the tool and click Decode. The decoded output can then be converted back into an image file format such as PNG or JPG.
How to encode Base64 manually?
Manual base 64 encoding involves converting binary data into ASCII text using a Base64 index table. Each group of 3 bytes becomes 4 encoded characters. However, using a base64 encode online tool is much faster and easier.
