  • Load image files locally from your device

  • On-device processing — images never uploaded to a server

Image-to-Base64 — not a human-readable text encoder

Pix-8 Base64 Encoder reads a local image file and outputs a Base64 string in the browser — not a text field that converts human-readable strings or paragraphs to Base64. Toggle the data URL prefix, review character and byte size, then copy in one step. It does not encode plain text, batch-process folders, or decode Base64 back to images.

Why use image-to-Base64 in the browser?

Generic human-readable to Base64 converters often run in the cloud and mix text and file workflows in one form. Pix-8 keeps image encoding local — the practical fit when you need to convert visual assets to Base64 for inline CSS or HTML without routing image files through a remote server.

Clear scope: image files

Load a PNG, JPEG, WebP, or GIF from your device and get a Base64 string — the workflow for embedding icons and small graphics. Pix-8 does not encode human-readable text input.

Client-side by default

Your image is read and encoded in the browser tab via FileReader. Pix-8 never receives your pixel data during encoding or copy.

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

  1. Step 1

    Open Base64 Encoder

    Navigate to Pix-8 Base64 Encoder in your browser — no install, no account, and no upload dialog.

  2. 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.

  3. 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. Plain-text encoding is not supported.

Frequently asked questions

Can I convert human-readable text to Base64 with this tool?

No. Pix-8 Base64 Encoder converts image files from your device into Base64 strings — it does not accept typed, pasted, or human-readable plain text and encode it to Base64. If you need a Base64 string from a local PNG, JPEG, WebP, or GIF for CSS or HTML, load the image file and copy the encoded output on-device.

Does converting human-readable content to Base64 upload 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 can this human-readable to Base64 converter actually encode?

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 encode human-readable text, batch-process folders, decode Base64 back to images, or convert video files.
