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 strings back into downloadable images.

Base64 string to image converter — image-to-Base64, not decoding
Searching for a Base64 string to image converter? Pix-8 Base64 Encoder converts image files to Base64 strings in your browser — no upload, no account, no cloud queue. Load a local PNG, JPEG, WebP, or GIF, 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 image files.

- Character and byte size readout for the encoded output
- On-device processing — images never uploaded to a server
Image-to-Base64 — not Base64 string to image decoding
Pix-8 Base64 Encoder reads a local image file and outputs a Base64 string in the browser — not a converter that ingests pasted Base64 and exports a decoded image. 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 converters often upload strings or files 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 via FileReader. 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 locally
Choose a PNG, JPEG, WebP, or GIF from your device. The browser reads the file on-device and encodes it to Base64 via FileReader.
Step 3
Copy the encoded string
Review character and byte size, toggle the data URL prefix if needed, then copy — ready for CSS, HTML, or email. Base64-to-image decoding is not supported.
Frequently asked questions
Can I convert a Base64 string to an image 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 a downloadable image or preview file. 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 converting Base64 to image 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 strings to images, decode Base64 to text, encode plain text, or batch-process folders.
