Base64 Viewer Online: Decode and View Encoded Data Instantly
Have you ever come across a long string of letters and numbers in an API response or a log file and wondered what it meant? That's most likely Base64 encoded data, a format used to represent various files—from images and PDFs to text documents—as simple text. While it's great for data transfer, it's completely unreadable to the human eye.
Our free online Base64 Viewer is a simple and secure tool that instantly decodes any Base64 string. Just paste your text, and you'll get a clear, readable preview of the original content. It's the fastest way to get a glimpse of what's inside a Base64 string without writing a single line of code.

Frequently Asked Questions
-
Q: What kind of data can a Base64 string contain? A: A Base64 string can be used to encode any binary data, including images (JPG, PNG), documents (PDF), videos, audio, and even plain text. The viewer will attempt to show a preview of whatever the string represents.
-
Q: Is it safe to paste a Base64 string into an online tool? A: Yes, it is safe when using our tool. Because the processing is done entirely on your device, your data is never sent to our servers.
-
Q: Why is Base64 encoding used if it makes files larger? A: While Base64 strings are larger than their original files, they are used to ensure data integrity during transfer over text-only protocols like HTTP or in systems that only support text. This ensures the data is not corrupted.
