Base64 is an encoding method used to make data secure and readable in text form. Its primary purpose is to convert binary data into ASCII characters. Thanks to this method, emails, web API requests, JSON data, URL parameters, or images can be transmitted safely.
Simply put, Base64 encoding represents a file or text in a textual form, while Base64 decoding converts that encoded text back to its original state. This allows data to be transferred across the network without corruption or character loss.
The Base64 Encoder / Decoder tool on this page lets you convert any text or file to Base64 format or decode from Base64 back to original.
All operations occur directly in your browser — none of your uploaded data is stored on our servers. This guarantees 100% privacy and data security.
This tool is ideal for developers, designers, system administrators, and web users.
The Base64 format is widely used for embedding images in HTML or CSS, securely sending data in API requests, creating JWT (JSON Web Tokens), email attachments, or transporting text-based data.
Base64 makes your data UTF-8 compatible so it can be transferred across networks without corruption.
This eliminates issues caused by special characters, line breaks, or binary data.
Base64 is supported by almost all programming languages.
You can encode data in PHP, JavaScript, Python, C#, Java, Go, etc., and decode it accurately on any other platform.
Base64 is not an encryption method; it is a conversion algorithm.
No data is lost; every encoding operation produces the same result, and decoding restores it exactly.
Our tool converts your data into Base64 format in seconds.
If you have a Base64 string, paste it into the field to instantly retrieve the original content.
All of these operations work online and for free, locally on your device.
No plugins or extra software are required.
Base64 can be used in many areas — from software development and web design to data transfer and secure communication:
Web Development: Embed images in HTML/CSS as “data URI”
API Integrations: Send binary data inside JSON
Data Storage: Store data in text-based formats
Email Systems: Send attachments as text
Pre-Encryption Conversion: Convert binary data to text for secure transmission
No. Base64 is not an encryption algorithm; it is a data representation method.
It does not hide data; it only encodes it in a different form.
Therefore, when confidentiality is required, it should be used together with cryptographic methods such as AES, RSA, or SHA-256.
The purpose of Base64 is not to hide data but to increase portability and ensure character compatibility.

Base64 converts binary data into ASCII characters. This allows data to be safely transferred via email, APIs, or web applications.
Paste your Base64-encoded text or file string into the “Decoder” section to instantly get the original content.
Base64 ensures reliable data transfer, but it is not encryption.
Additional cryptographic methods must be used to ensure data privacy.
You can convert any text files (txt, json, html, csv) and images/documents (jpg, png, pdf) to and from Base64 format.
The Base64 Encoder / Decoder is a modern tool designed for developers, students, and technical users.
It converts and restores your data in seconds and lets you use it any way you need.
It runs entirely online without any installation, protects your privacy, and provides maximum speed.
If you want to perform Base64 operations safely, quickly, and easily — you’re in the right place.
