How to Use the Image to Base64 Converter

  1. Drag and drop an image into the upload area, or click browse files to select one from your device.
  2. The Base64 data URI appears automatically as soon as the file loads.
  3. Pick Data URI (full) for a copy-paste-ready string, or Base64 only for just the encoded payload.
  4. Click Copy to Clipboard to copy the string, or Download .TXT to save it as a text file.

Privacy and Client-Side Security

Privacy Guarantee: All conversion occurs locally inside your browser. Your files and data are never transmitted, stored, or recorded on remote servers.

Many online Base64 converters ask you to upload your image before processing. That creates privacy risk for personal or work images. TinyToolzz takes a different approach: the Image to Base64 conversion happens entirely on your device using the FileReader API.

The Base64 string and the preview are both produced in your browser memory. Nothing is sent over the network, stored, logged, or shared. When you leave the page or click Reset, the image data is released from memory.

Frequently Asked Questions

What is a Base64 image?
A Base64 image is a text representation of an image file that uses only ASCII characters. It is often used as a data URI in CSS or HTML to embed images directly into the source code, reducing the number of HTTP requests.
What image formats can I convert?
You can convert any image format that your browser can read, including JPG, PNG, GIF, WebP, SVG, AVIF, HEIC, and BMP. The tool encodes the raw file bytes directly with the FileReader API, so no format is re-encoded or altered.
Is my image uploaded to a server?
No. The entire conversion happens inside your browser using the FileReader API. The image is never transmitted to any server, so your data stays completely private.
How long is the Base64 string?
The length depends on the image size and format. Typically, the Base64 string is about 33% larger than the original binary file. The tool displays the exact character count after conversion.
How do I use the Base64 string?
Paste the data URI directly into CSS (e.g. background-image: url('data:image/png;base64,...')), into HTML <img src="data:image/png;base64,...">, or into JavaScript to embed an image dynamically. The tool gives you a ready-to-copy string.
Why would I need to convert an image to Base64?
Using Base64 images eliminates external image files, which reduces the number of HTTP requests and can speed up page loads for small images. It's also useful when you want to embed an image in a single HTML file or email.
