Honest image-to-Base64 flow
Load an image file from your device and get a Base64 string — the encoding direction developers need for inline assets. Pix-8 does not decode pasted Base64 back into downloadable images.

What this tool does

- 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 string-to-image 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 exports a decoded image. Toggle the data URL prefix, review character and byte size, then copy in one step. It does not accept Base64 text input, batch-decode folders, or reconstruct images from clipboard strings.
Why use Base64 for images online in the browser?
Cloud Base64 tools often upload files before encoding or decoding. Pix-8 keeps image-to-Base64 conversion local — the practical fit when you need Base64 for images online without routing source files 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 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
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 an image file from your device. The browser reads it on-device and converts it to a Base64 string with an optional data URL prefix.
Step 3
Copy the encoded string
Review character and byte size, then copy the output — ready to embed in CSS, HTML, or email. Not a decode-to-image export.
Frequently asked questions
Is this a Base64 decoder that turns strings back into images?
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 file. If you need a Base64 string from a local image for CSS, HTML, or email, this tool encodes on-device without uploading to a server.
Does this Base64 tool upload my files 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 shown as a copy-ready string. It is never transmitted to Pix-8 or any third-party server.
What output can I copy from this online Base64 tool?
Base64 Encoder produces a Base64 string from a local image file — with an optional data:image/…;base64, prefix for inline CSS or HTML. Character and byte size are shown before you copy. It does not decode existing Base64 text, batch-process folders, or encode plain text.
