Honest encoding scope
Load an image file and get a Base64 string — the forward direction for inline assets. Pix-8 does not decode pasted Base64 back into text or downloadable images.

Decode Base64 to text — image encoding, not decoding
Searching to decode Base64 to text? Pix-8 Base64 Encoder converts image files to Base64 strings in your browser — no upload, no account, no cloud queue. Load a local image, generate a copy-ready string with an optional data URL prefix, and embed it in CSS or HTML — all on-device. This tool does not accept pasted Base64 and decode it back into plain text or image files.

What this tool does
- Load image files locally from your device
- Generate Base64 strings with optional data URL prefix
- Copy output ready for CSS, HTML, or email templates
- Character and byte size readout for the encoded output
- On-device processing — images never uploaded to a server
Image-to-Base64 — not Base64-to-text decoding
Pix-8 Base64 Encoder reads a local image file and outputs a Base64 string in the browser — not a decoder that ingests pasted Base64 and reveals plain text or exports a decoded file. Toggle the data URL prefix, review character and byte size, then copy in one step. It does not decode Base64 input, encode plain text, or batch-process folders.
Why use image-to-Base64 in the browser?
Cloud Base64 decoders often upload strings before processing. Pix-8 keeps image encoding local — the practical fit when you need to work with Base64 for images without sending source files or encoded strings through a remote server.
Client-side by default
Your image is read and encoded in the browser tab. Pix-8 never receives your pixel data or pasted Base64 strings during use.
Copy-ready output
Optional data:image/…;base64, prefix, character and byte readout, and one-click copy — formatted for CSS, HTML, or email templates.
How it works
Step 1
Open Base64 Encoder
Navigate to Pix-8 Base64 Encoder in your browser — no install, no account, and no upload dialog.
Step 2
Load an image file
Choose an image from your device. The browser encodes it on-device to a Base64 string — not a paste field for decoding existing Base64.
Step 3
Copy the encoded string
Review character and byte size, then copy the output for CSS, HTML, or email. Base64-to-text decoding is not supported.
Frequently asked questions
Can I decode Base64 to text with this tool?
No. Pix-8 Base64 Encoder converts image files into Base64 strings in your browser — it does not accept pasted Base64 input and decode it back into plain text or a downloadable image. If you need a Base64 string from a local image for CSS, HTML, or email, load the image file and copy the encoded output on-device.
Does decoding or encoding Base64 upload my data to a server?
No. Pix-8 Base64 Encoder runs entirely in your browser. Your image file is read locally via the FileReader API, encoded on-device, and displayed as a copy-ready string. It is never transmitted to Pix-8 or any third-party server.
What does Pix-8 Base64 Encoder actually do?
Base64 Encoder converts local image files into Base64 strings with an optional data:image/…;base64, prefix. Character and byte size are shown before you copy. It does not decode Base64 to text, decode Base64 to images, encode plain text, or batch-process folders.
